How to Make Measurements
AC Voltage
The sections that follow tell how to make measurements
with the Meter.
Switch Box
To connect the test leads to the circuit or device, connect
the common (COM) test lead first. To remove the test
leads, remove the common test lead last.
AC and DC Voltage Measurements
The voltage ranges are 600.0 mV, 6.000 V, 60.00 V,
600.0 V, and 1000 V. To set the 600.0 mV dc or ac range,
turn the function switch to . Millivolts ac is set first.
Push to switch to millivolts dc.
Refer to Figure 1 to measure ac or dc voltage.
For voltage measurements, the Meter puts approximately
10 MΩ (10,000,000 Ω) in parallel with the circuit. This load
can cause measurement errors in high-impedance circuits.
In most cases, the error is negligible (0.1 % or less) if the
circuit impedance is 10 kΩ (10,000 Ω) or less.

before resistance measurements.
current in the next higher range. If the value is higher,
use the higher value. Refer to the Input Parameters
table in the specifications section for typical shortcircuit currents.
The Meter sends a small current through the circuit for
resistance measurements. Because this current flows
through all possible paths between the probes, the
resistance measured is the total resistance of all paths
between the probes.
The resistance ranges are 600.0 Ω, 6.000 kΩ, 60.00 kΩ,
600.0 kΩ, 6.000 MΩ, and 40.00 MΩ.
Set the Meter as shown in Figure 2 to measure resistance.
Below are some hints for resistance measurements:
•
The measured value of a resistor in a circuit is
frequently different from the specified resistor value.
•
The test leads can add 0.1 Ω to 0.2 Ω of error to
resistance measurements. To measure test lead
resistance, touch the probe points together and read
the resistance.
•
The resistance function uses sufficient voltage to
forward-bias silicon diode or transistor junctions, and
cause current to flow. If you think current flows
through the junction, push to apply a lower

Temperature Measurements
The Meter measures the temperature of a type-K
thermocouple (included). Choose between degrees
Celsius (°C) or degrees Fahrenheit (°F) by pushing
C.
W Caution
To prevent possible damage to the Meter or
other equipment, use a thermocouple rated
for the temperatures to be measured. The
Meter is rated for -40.0 °C to +400.0 °C and
-40.0 °F to 752 °F, but the included type-K
thermocouple is rated to 260 °C.
Continuity Tests
WCaution
To prevent possible damage to the Meter or
the equipment under test, disconnect power
and discharge all high-voltage capacitors
before a continuity test.
The continuity test uses a beeper that sounds when a
closed circuit is sensed. The beeper lets you do continuity
tests without the necessity to look at the display.
To do a continuity test, set up the Meter as shown in
Figure 3.
The temperature ranges are -40.0 °C to +400 °C and
-40.0 °F to 752 °F. All other temperatures show on the
display. When there is no thermocouple connected, the
display shows .
To measure temperature:
1.
Connect a type-K thermocouple to the COM and
terminals of the Meter.
2.
Turn the function switch to .
3.

Diode Tests
WCaution
To prevent possible damage to the Meter or
to the equipment under test, disconnect
power and discharge all high-voltage
capacitors before a diode test.
Do a diode test on diodes, transistors, silicon controlled
rectifiers (SCRs), and other semiconductor devices. This
function sends a current through the semiconductor
junction and then measures the voltage drop across the
junction. A good silicon junction drops between 0.5 V and
0.8 V.
To do a diode test on a diode out of a circuit, set up the
Meter as shown in Figure 4. For forward-bias
measurements on a semiconductor component, put the
red test lead on the positive terminal of the component
and put the black test lead on the negative terminal of the
component.
In a circuit, a good diode has a forward-bias
measurement of 0.5 V to 0.8 V. A reverse-bias
measurement includes the resistance of other pathways
between the probes.
A short beep sounds if the diode is good (<0.85 V). A
continuous beep sounds if the measurement is ≤0.100 V
or short circuit. The display shows “” if the diode is
open.

AC and DC Current Measurements
XWWarning
To prevent possible electrical shock or
personal injury, do not make an in-circuit
current measurement where the open-circuit
potential to earth is >1000 V. Meter damage
or injury can occur if the fuse blows during
such a measurement.
WCaution
To prevent possible damage to the Meter or
to the equipment under test:
•
Do a fuse test before current
measurements.
•
Use the correct terminals, function, and
range for all measurements.
•
Do not put the probes across (in parallel
with) a circuit or component when the
test leads are connected to the current
terminals.
To measure current, you must break the test circuit, then
put the Meter in series with the circuit.
24
The current ranges are 6.000 A, and 10.00 A. AC current
is shown as an rms value.
To measure current (see Figure 6):
1.
Remove power from the circuit. Discharge all highvoltage capacitors.
2.
Put the black test lead into the COM terminal. Put the
red test lead into the A terminal.
3.
Set the function switch to for ac current or for
dc current.

Frequency Measurements
A frequency measurement is a count of the number of
times an ac voltage or current signal crosses a threshold
point each second.
To make a frequency measurement:
1.
Set the function switch to for voltage or for
current.
2.
Connect the Meter to the signal source.
3. Push .
The Meter autoranges to one of four frequency ranges:
99.99 Hz, 999.9 Hz, 9.999 kHz, and 50 kHz.
Below are some hints for frequency measurements:
•
If a measurement shows as 0 Hz or is not stable, the
input signal can be below or near the trigger level. A
lower range increases the sensitivity of the Meter and
can usually repair these problems.
•
An input signal with distortion can cause a frequency
measurement to be higher than usual. The distortion
can cause multiple triggerings of the frequency
counter. A higher voltage range decreases the input
sensitivity and can correct this problem. In general,
the lowest frequency is the correct one.
26
Remote Operation
The Meter uses low-power 802.15.4 wireless technology
to allow the display module to operate in a different
location than the Meter base. Although there is control of
some Meter functions (Hold, MIN MAX AVG, Range, and
Backlight), complete remote control of the Meter is not
available through the display module.
The wireless radio does not interfere with meter
measurements. Usually, the radio is off when the display
module is docked on the Meter base. It is possible for the
radio to be on when the display module is docked and the
function switch is set to OFF. To make sure that the radio
is off, remove the batteries from the Meter base and
display module.
The display module is synchronized with a Meter base
when it is docked on the Meter base and turned on.
Different display modules can be synchronized with a
Meter base but, only one display module can be
synchronized to a Meter base at the same time.

Remote Operation
Remove the Display Module
To remove the display module (see Figure 7):
1.
Push in on the latches on the sides of the display
module.
2.
Pull the display module off of the top end of the
Meter base.
The Meter base and display module can be a maximum
of 10 Meters (30 feet) from each other before the radio
connection is broken. This distance can change if
obstacles are between the Meter base and the display
module. There is a radio connection between the display
module and Meter base when shows in the display.
When the display module and Meter base lose the radio
connection, the display shows dashes and blinks.
Possible causes for this loss are the distance is too far for
the environment or the batteries in the Meter base are
dead. To reconnect, decrease the distance between the
display module and Meter base.
