- Now connect the two measuring prods to the object to be measured (generator,
switching etc.).
- The measuring value is indicated on the display
- After measuring, remove the measuring leads from the measuring object and
turn the meter off. Turn the rotary switch to „OFF“.
c) Resistance measurement
ƽ
Make sure that all the circuit parts, switches and components
and other objects of measurement are disconnected from the
voltage at all times.
Proceed as follows to measure resistances:
- Turn the meter on at the rotary switch and select measuring range „Ω“.
- Plug the red measuring lead into the Ω-measuring socket (11) and the black
measuring lead into the COM measuring socket (10).
- Check the measuring leads for continuity by connecting both measuring prods to
one another. After that the resistance value must be approximately 0.5 Ohm
(inherent resistance of the measuring leads).
- Press the button „REL“ (8) to not let the inherent resistance of the measuring leads
to affect the following resistance measuring. The display shows 0 Ohm
- Now connect the measuring prods to the object to be measured. As long as the
object to be measured is not high-resistive or interrupted, the measured value
will be indicated on the display. Wait until the display has stabilised. With resis-
tances of >1 MΩ , this may take a few seconds.
- As soon as „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 measuring object and
turn the meter off. Turn the rotary switch to „OFF“.
☞
If you carry out a resistance measurement, make sure that the mea-
suring points which you contact with the test prods are free from dirt,
oil, solderable lacquer or the like. An incorrect measurement may
result under such circumstances.
