e) Continuity test
1. Turn the DMM on and select measuring range
2. Insert the red measuring lead into the
COM socket (9).
3. Check the measuring leads for continuity by connecting both measuring prods to one another.
After that the value must be approximately 0 V. An acoustic signal can be heard.
4. Now connect the two measuring prods to the two contact points for checking continuity.
5. The display shows the continuity voltage in volt (V).
6. If "1" (towards the left side of the display) is shown, the two contact points are not in a closed circuit.
If the two end points are in a closed circuit, the resistant is less than 10 Ω, an acoustic signal
can be heard.
7. After measuring, remove the measuring leads from the measuring object and turn the DMM
off. Turn the rotary switch (5) to the position "OFF" .
f) Non contact voltage test "NCV"
Make sure that all measuring sockets are unoccupied. Please remove all
measuring leads and adapters from the measuring device.
This function only serves as aid. Prior to performing work on these cables,
you have to perform contact measuring operations to check for the absence
of voltage.
1. Turn the DMM on and select measuring range "NCV" with the rotary switch (5). You will see
the word "NCV" on the display (4).
2. Test this function beforehand on a known AC voltage source.
3. Guide the measuring device with the sensor area (3) towards to position to be tested at a
distance of max. 5 mm. In case of twisted cables, it is recommended to check the cable at a
length of approx. 20 to 30 cm.
4. In case voltage is detected, the will be an acoustic signal.
5. After you finish measuring, turn the DMM off. Turn the rotary switch to the position "OFF".
