RMO600 non
Micro OhmMeter
RMO600
High DC current reslstance meter
Micro OhmMeter
Description
Applications
Typical application is measuring resistance of:
n High, middle and low voltage circuit breakers
n High, middle and low voltage disconnecting switches
n High-current bus bar joints
n Cable splices
n Welding joints.
Description
RMO600 is a micro-ohmmeter based on state of the art technology, using the most
advanced switch mode technique available today. RMO600 generates true DC current
with automatically regulated test ramps. During the test RMO600 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 -button.
The RMO600 instrument can store up to 500 measurements. All measurements are time
and date stamped. Using RMOWin-V2 software a test can be performed from a PC, and
the results can be obtained directly at a PC. Using RMOWin-V2 the result can be arranged
as an Excel spreadsheet which can be later shown as a diagram and printed for a report.
The set is equipped with thermal and overcurrent protection. The RMO600 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.
Output Ratings
The full output is available from the RMO600 at 230V or 115V Mains Supply. A reduced
output is available from lower supply voltages.
Supply Voltage Output Current Full Load Voltage
230V AC 600A DC smoothed 5,0V DC
300A DC smoothed 6,0V DC
115V AC 600A DC smoothed 3,0V DC
300A DC smoothed 5,0V DC
Output current is filtered and has a ripple of less then 1%. The RMO600 current output
is rated 600A for 1 minute, at 300A for 2 minutes and 200A continuously at 25
.
C ambient.
CONT Mode
RMO600 can generate DC current continuously using the CONT menu. In this menu the
current can be chosen the same way like in the SINGLE menu, but the duration of the
test can be preset.
The test is started pressing the -button. During the test, a new result is shown on the
display and stored into the PC (RMOWin-V2) each second. Using RMOWin-V2 the result
can be arranged as an Excel spreadsheet which can be later shown as a diagram and
printed for a report.
