VOLTCRAFT VC-539 Mode D'emploi page 36

Resistance
1. Connect the test prods to the object under test.
Make sure that the object under test is free of dirt, oil, soldering varnish, etc. as the presence
of such residue may falsify readings.
2. The reading is shown on the LC display (10). Wait until the reading stabilizes.
If the LC display shows OL (overload), the measurement range was exceeded or the
measuring circuit interrupted.
3. Remove the test leads from the object under test after measurement and turn off the current
clamp.
Diode test
1. Connect the test prods to the diode under test.
2. The forward voltage is shown in volt (V) on the LC display (10). The value should be between
0.4 V and 0.7 V.
If the LC display shows OL (overload), the diode is being measured in the reverse direction or
is defective. For checking purposes, conduct a measurement on the opposing poles.
3. Remove the test leads from the object under test after measurement and turn off the current
clamp.
Continuity test
1. Connect the test prods to the object under test.
2. An acoustic signal sounds for resistances <150 Ω.
If the LC display shows OL (overload), the measurement range was exceeded or the
measuring circuit interrupted.
3. Remove the test leads from the object under test after measurement and turn off the current
clamp.
