Protective earth resistance meter RMO60E

 Lightweight – only 7,5 kg

 Powerful 10 A – 60 A DC

 Measuring range 100 µΩ – 999,9 m

 Resolution to 0,1 

 SINGLE / CONTIN Mode

 Mechanical protection IP43

Description

RMO60E is ideal for testing the protective

bonding (grounding) of equipment following

the standard 61010-1 IEC 2001.This standard

specifies for plug connected equipment and for

permanently connected equipment the following

requirements:

The protective earth resistance should be below

0,1Ω or voltage between the protective

conductor terminal and each accessible

conductive part for which protective bonding is

required not to exceed 10V.

Conformity is checked by applying a test current

for 1 minute and then calculating impedance, or

measuring the voltage between the protective

conductor terminal and each accessible

conductive part for which protective bonding is

required.

The test current should be greater of 25A or

twice the rated current for plug connected

equipment, or twice the value of the overcurrent

protection for the permanently connected

equipment.

For both of these applications RMO60E can

provide the right tool for verification of the

conformity. Applying current up to the value of

60A and the ability of RMO60E to provide in the

Contin menu (continuous operation) test current

for the pre-set test duration (equal or exceeding

1 min) - gives an user possibility to easily

check the protective bonding/grounding of the

equipment. The full load voltage of 12V assures

that the measurement is executed properly and

that the result obtained (pass fail classification)

is accurate.

RMO60E generates true DC current with

automatically regulated test ramps. During the

test RMO60E ramps with increasing current

before measuring and decreasing current after

the measurement. This eliminates magnetic

transients. After the test current has been set,

the automatic test procedure is started by

pressing the Ω-button.

The RMO60E instrument can store up to 500

measurements. All measurements are time and

date stamped. Using DV-Win software a test can

be performed from a PC, and the results can be

obtained directly at a PC Communication

between RMO60E and PC is through USB or

RS232 cable. Using DV-Win the result can be

arranged as an Excel spread sheet which can

be later shown as a diagram and printed for a

report.

The set is equipped with thermal and

overcurrent protection. The RMO60E has very

high ability to cancel electrostatic and

electromagnetic interference in HV electric

fields. It is achieved by very efficient filtration.

The filtration is made utilizing proprietary

hardware and software.

CONTIN Mode

RMO60E can generate a DC current

continuously using the CONTIN menu. In this

menu the current can be chosen the same way

as in the SINGLE menu, but the duration of the

test can be preset. The test is started pressing

the Ω-button. During the test, a new result is

shown on the display and stored into the PC

(DV-Win) each second. Using DV-Win the result

can be arranged as an Excel spreadsheet which

can be later shown as a diagram and printed for

a report.

Application
