Diode Test; Continuity Check - VOLTCRAFT CT-3 Notice D'emploi

d) Diode test
Make sure that all the circuit parts, switches and components and
other objects of measurement are disconnected from the voltage
at all times.
Select measuring range
- The display indicates the diode symbol.
- Check the measuring leads for continuity by
connecting both measuring prods to one
another. After that the value must be approxi-
mately 0 V.
- Now connect the two measuring prods with
the object to be measured (diode).
- The display shows the continuity voltage in V.
If „OL" is indicated, the diode is measured in
reverse direction or the diode is faulty (inter-
ruption).
e) Continuity check
Make sure that all the circuit
parts, switches and components and other objects of measure-
ment are disconnected from the voltage at all times.
Select measuring range
To activate the acoustic continuity tester function, press the button „MODE" (3). If
you press the button again, the device switches back to the diode test mode, etc.
The „continuity check" symbol appears on the display.
- A measuring value of less than 150 Ohm is identified as continuity; in this case a
beep sounds.
- As soon as „OL." (overflow) appears on the display, you have exceeded the mea-
suring range or the measuring circuit has been interrupted.
