Users Manual

Operation

The Product is easy to use. The rotary dial clearly indicates the selected

function. Push buttons help you to quickly modify the test settings. The

large display with backlight shows the test results in clear symbols on a

one-level menu.

Safety Features

Safety and performance are two of the most critical requirements for any

electrical system. Good quality insulation, a properly working grounding

system, and active protection assure the safety of people, electrical

systems and buildings. These factors protect them against electrocution,

fire, and other equipment damage.

Touch Pad

The  button is surrounded by a touch pad (see Table 6). The touch pad

measures the potential between the operator and the PE terminal on the

Tester. If the touch pad potential exceeds 100 V, the W symbol above the

touch pad is lit, the PE annunciator in the display is lit, and the beeper

sounds.

Live Circuit Detection

For continuity and insulation resistance measurements, the Product inhibits

the test if the terminal voltage detected is >30 volts ac/dc before the test

starts. The beeper sounds continuously if this voltage is present.

Earth Resistance Measurement

The Product inhibits the test if >10 volts is detected between the test rods.

More information about Earth Resistance measurements is on page 55.

Safety Pretest

The 1664 FC model includes a Safety Pretest feature that detects any

appliances connected to the circuit under test. The Safety Pretest gives

you a warning before you start a test and prevents damage to appliances

from the test voltage. More information about Safety Pretest is on page 26.

Electrical Installation Tester

How to Zero the Test Leads

XW Warning

To prevent possible electrical shock, fire, or personal injury,

do not use in CAT III or CAT IV environments without the

protective cap installed. The protective cap decreases the

exposed probe metal to <4 mm. This decreases the

possibility of arc flash from short circuits.

Test leads have a small amount of inherent resistance that can affect a

measurement. Before you do continuity or loop impedance tests, use the

zero adapter to compensate for, or zero, the test leads or the mains cord.

See Figure 2 and Figure 3 for more information about the zero adapter.

Electrical Installation Tester

Operation

The Tester maintains a separate zero value for each continuity range and

loop impedance tests. A unique zero is stored for each lead combination in

each function that allows the zero mode. The  annunciator indicates

when a zero value is stored for the selected lead combination. For each

continuity range, zeros are valid for both polarities.

To zero:

1. Turn the rotary dial to the , , or  position.

2. For RLO, use  to select 10 mA or 250 mA range. A separate zero

value is retained for each range.

3. Connect the mains line cord (or the test leads) to the Tester and the

zero adapter. You can zero two or three test leads in the RLO function.

4. Press and hold  for 2 seconds to 6 seconds until the  annunciator

and the offset value show in the primary display. The beeper sounds

with each completed zero value.

The Tester measures the lead resistance, stores the value, and

subtracts it from readings. The resistance value is retained when the

power is turned off. If the Tester is the same function with the same

test leads or mains cord, you do not need to repeat the zero operation.

Loop/Line Impedance Measurements

Loop Impedance (Line to Protective Earth L-PE)

Loop impedance is source impedance measured between Line (L) and

Protective Earth (PE). You can determine the Prospective Earth Fault Current

(PEFC). PEFC is the current that could potentially flow if the phase conductor is

shorted to the protective earth conductor. The Tester calculates the PEFC as

the measured mains voltage divided by the loop impedance. The loop

impedance function applies a test current that flows to earth. If RCDs are

present in the circuit, they may trip. To avoid tripping, use the  function

on the rotary dial. The no trip test applies a special test that prevents RCDs in

the system from tripping. If you are certain no RCDs are in the circuit, you can

use the ZI High-Current function for a faster, less noisy test.

Note

If the L and N terminals are reversed, the Tester will auto-swap

them internally and continue the test. This condition is indicated

by arrows above or below the terminal indicator symbol (b).

If the Tester is configured for UK operation, L and N will not

auto-swap and the test stops.

Tips:

• Use the  position for loop measurements.

• Preload conditions can cause the RCD to trip.

• An RCD with a nominal fault current of 10 mA will trip.

• To test loop impedance in a circuit with a 10 mA RCD, see the Applications

section.

RCD Tripping Time Measurements

In this test, a calibrated fault current is induced into the circuit to cause the RCD

to trip. The meter measures and shows the time required for the RCD to trip.

You can do this test with test leads or the mains cord. The test is done with a

live circuit.

You can use the Tester to do the RCD tripping time test in Auto Start, which

makes it easier for one person to do the test. If the RCD has a special nominal

current setting other than the standard options, 10, 30, 100, 300, and 500, or

1000 mA, you can use a custom setting with the Var mode.

Note

When you make trip time measurements for any type of RCD,

the Tester first determines if the actual test will cause a fault

voltage exceeding the limit (25 V or 50 V). If yes,  shows

on the display.

To avoid having an inaccurate trip time for S type (time delay)

RCDs, a 30 second delay is activated between the pretest and

the actual test. This RCD type needs a delay because it

contains RC circuits that are required to settle before applying

the full test.

Electrical Installation Tester

Measurements

RCD type B, B+ (.) or S-type B, B+ (. G) are actually two RCDs, one with

type A/AC behavior and one with type B. The type B RCD is correctly tested

only with the trip current (ramp) test. For trip time measurements, even with

type B selected, the ac part of the RCD might cause the tripping because of the

initial step of the test current. Fluke recommends that you do a trip current test

with type B and a test with type A/AC waveform.

XW Warning

To prevent possible electrical shock, fire, or personal injury:

• Test the connection between the N-conductor and earth

before you start the test. A voltage between the N-conductor

and earth may influence the test.

• Leakage currents in the circuit that follow the residual

current protection device may influence measurements.

• The displayed fault voltage relates to the rated residual

current of the RCD.

• Potential fields of other earthing installations may influence

the measurement.

• Equipment (motors, capacitors) connected downstream of

the RCD may cause considerable extension of the tripping

time.

Note

If the L and N terminals are reversed, the Tester will

automatically swap them internally and continue tests. If the

Tester is configured for UK operation, tests will stop and you

will need to determine why the L and N are swapped. This

condition is indicated by arrows above the terminal indicator

symbol (b).

Type A and type B RCDs do not have the 1000 mA option

available. Type B RCDs do not have the Var option available.

When testing under a condition that would trip an RCD, but

does not (for example, reading is >310 ms), check the

connections, leads and fuses.

To measure RCD tripping time:

XW Warning

To prevent possible electrical shock, fire, or personal injury:

• Test the connection between the N-conductor and earth

before you start the test. A voltage between the N-conductor

and earth may influence the test.

• Leakage currents in the circuit that follow the residual

current protection device may influence measurements.

• The displayed fault voltage relates to the rated residual

current of the RCD.

• Potential fields of other earthing installations may influence

the measurement.

If the L and N terminals are reversed, the Tester will automatically swap them

internally and continue tests. If the Tester is configured for UK operation, tests

stop and you will need to determine why the L and N are swapped. This

The test current flows through the upper side of the RCD, into the L terminal,

and returns through the PE terminal.

To test an RCD at the mains socket, put the Tester into the IT mode (Power-on

option:  + ). In this mode the Tester accepts any voltage between N and

PE. The precondition for trip time and current measurements is that the

resistance of the earth ground system is low enough to allow the test current

flow.

How to Test a Mains Socket and Ring Installation

The mains socket test checks that the mains voltage is present, the frequency

is 50 Hz/60 Hz, and the wiring of the mains socket is correct.

For a valid socket test:

• connect all test leads (phase, neutral, and protective earth) to the mains

socket

• the mains line cord provides a quick connection to the socket

• always contact the touch pad around the test button

When a high voltage is measured between two wires,  shows on the display:

• If the PE wire is live and you contact the touch pad, the W above the touch

pad is lit, the PE annunciator in the display is lit, and the beeper sounds.

• If the L and N terminals are reversed, the Tester shows an arrow above the

terminal indicator symbol. The Tester automatically reverses these

internally and allows the test. When configured for UK operation, the

Tester inhibits the test.

• If the L and PE terminals are reversed, the Tester shows an arrow below

the terminal indicator symbol and inhibits the test.

• If the N, PE, or installation wire is open or broken, the Tester shows the

terminal as a crossed circle. The test can start if the wire is not required for

this test.

• If the trip time meets the appropriate standard of the RCD, the RCD 

indicator shows. For more information, see the RCD Tripping Time table in

the Specifications section of this manual.

Earth Resistance Test by Loop Method

You can also use the Tester to measure the earth resistance component of the

total loop resistance. Check your local regulations to determine if this method is

acceptable in your area. You can use three leads or the mains test cord to do

this test. Use the connection shown in Figure 13 when you make a 3-wire

connection for earth resistance loop test. Zero the test leads before the test

Zmax

Zmax compares multiple line/loop impedances and retains the maximum

impedance. Sockets on a circuit can be tested consecutively and the maximum

impedance value retained and stored to memory.

There are two types of Zmax values: Zmax (L-PE) and ZI Zmax (L-N). The input

selection determines which Zmax value is in use:

• Z

L No Trip

- L-N: ZI Zmax is in use

- L-PE: both ZI Zmax and Zmax are in use

• Z

L Hi Current

- L-N: ZI Zmax is in use

- L-PE: Zmax is in use

The Zmax values are retained when you switch between ZL No Trip and

ZL Hi Current. Zmax values are saved with the test result to memory. If you

change the location fields a, b, or c before you save, the actual test result is the

new Zmax.

Loop Impedance Test with 10 mA RCD

For a Loop impedance measurement in a 10 mA RCD circuit, the tripping time

RCD test is recommended. Use a nominal test current of 10 mA and the factor

x ½ for this test.

If the fault voltage is <25 V or 50 V, dependent on the local requirement, the

loop is good. To calculate the loop impedance, divide the fault voltage by 10

mA (Loop impedance = fault voltage x 100).

Auto Test Sequence (1664 FC)

The 1664 FC includes the Auto Test feature. Auto Test allows you to start

multiple tests with one press of :

• Line test (L-N)

• NoTrip Loop test (L-PE)

• RCD test:

o Ramp test (type A or type AC, 30 mA, 100 mA, 300 mA)

-or-

o Auto RCD test (type A or type AC, 30 mA, 100 mA)

• Insulation tests:

o L-PE, 50 V to 1000 V

o L-N, 50 V to 1000 V

o N-PE, 50 V to 1000 V

The Tester starts with the Line/Loop test, then it tests the RCD. After the RCD

has tripped, it proceeds with insulation tests. The insulation Safety Pretest and

the Zmax are always active.

This test sequence is intended to be done at a mains socket with the mains test

cord at circuits that are protected by an RCD with a nominal fault current of

≥30 mA.

Note

The automatic test sequence will trip an RCD. Because an

insulation test is part of the sequence, make sure that no

appliances are connected to the circuit under test.

If the L and N terminals are reversed, the Tester will auto-swap

them internally and continue the tests. If the Tester is configured

in L-n mode (no auto lead swap), tests are stopped. This

condition is indicated by arrows above the terminal indicator

symbol (b).
