RMO200D Getting Started
6 Getting Started
6.1 Connecting a Test Object to RMO200D
Before you connect a test object to RMO200D, make sure that:
• the test object is disconnected or separated from its circuit in accordance with the national safety
regulations,
• the test object is properly grounded to protective earth (PE),
• RMO200D itself is properly grounded. To do so, connect the grounding screw on the back of
RMO200D
‟s to PE using a grounding cable.
To maximize accuracy and measurement repeatability; make sure that all clamps have a good connection to
the test object and avoid any connection between Sense and Current clamps.
On/Off
Connect the earth/ground lead first before doing any connections to the test object.
Connect the mains lead to a mains outlet 100 V
– 240 V AC and turn on RMO200D with the power switch
on the test set. The first shown on the display is the name of the product followed by the instrument model
type and the internal firmware version.
6.2 Setting the Measurement Parameters
Single Test
Turn on RMO200D with the power switch on the test set. The display shows the Single menu and the green
LED lights up.

With RMO200D turned off, connect
RMO200D to the test object (R
X
) in
such a way that the measuring cables
from the "Voltage Sense" sockets are
attached as close as possible to R
X
,
and in between the current feeding
cables. That way, resistance of both
cables
and clamps is almost
completely excluded from the
resistance measurement.
Pay attention to polarity while
connecting
measuring cables.
Measuring results will be incorrect
as a consequence of error.
