D) Measuring Resistance "200 Kω; Hold Function - VOLTCRAFT ET-02 Bedienungsanleitung

d) Measuring resistance "200kW"
Make sure that all the circuit parts, switches and components and other objects of
measurement are disconnected from the voltage and discharged.
The alligator clip leads supplied can be used for resistance measurements. The alligator clips are
nonetheless large and it is recommended that you use optional measuring leads with testing probes. The
description as follows is given under the assumption of use of such optional measuring leads with testing
probes.
Proceed as follows to measure the resistance:
- Turn the DMM on and select measuring range "200 kW".
- Plug the red measuring lead into the Ω measuring socket
(10) and the black measuring lead into the COM measuring
socket (11).
- Check the measuring leads for continuity by connecting both
measuring probes with one another. The resistance value must
set to approximately 0 - 0.5 Ohm (inherent resistance of the
measuring leads) accompanied by a beep tone.
- Connect the measuring probes to the object to be measured.
As long as the object to be measured is not high-Ohm or inter-
rupted, the measured value will be indicated on the display.
Wait until the displayed value has stabilised.
- If "OL" (overload) appears on the display, you have exceeded
the measuring range or the measuring circuit has been broken.
- After measuring, remove the measuring leads from the measured object and turn the DMM off.
If you carry out a resistance measurement, make sure that the measuring points which you
contact with the measuring probes are free from dirt, oil, soldering paint or similar. An incor-
rect measurement may result under such circumstances.

HOLD Function

The HOLD function freezes the currently indicated measured value to allow you to read it or to take the
record without rushing.
If you test live wires make sure that this function is deactivated before the measure-
ment starts. Otherwise, the measurement will be false!
To switch on the HOLD function press the "HOLD" button (3); "HOLD" appears on the display.
