d) Diode test
ƽ
Make sure that all the circuit parts, switches and components
and other objects of measurement are disconnected from the
voltage at all times.
- Turn the meter on at the rotary switch and select measuring range Ω/.
- Insert the measuring leads to the measuring instrument in the same way as for
resistance measurement.
- Select the diode test function with the MODE key (7).
- The display indicates the diode symbol.
- Now connect the two measuring prods with the object to be measured (diode).
- The display shows the continuity voltage in volt (V). If „OL“ is indicated, the diode
is measured in reverse direction or the diode is faulty (interruption). Perform a
counter-pole measuring for control reasons.
- After measuring, remove the measuring leads from the measuring object and
turn the meter off. Turn the rotary switch to „OFF“.
e) Continuity check
ƽ
Make sure that all the circuit parts, switches and components
and other objects of measurement are disconnected from the
voltage and discharged.
- Turn the meter on at the rotary switch and select the measuring range.
- Insert the measuring leads to the measuring instrument in the same way as for
resistance measurement.
- To activate the acoustic continuity test function, press the „MODE“ key (7) twice.
- The display indicates the symbol „Continuity test“.
- A measuring value of less than 100 Ohm is identified as continuity; in this case a
beep sounds.
- As soon as „OL“ (overload) appears on the display, you have exceeded the
measuring range or the measuring circuit has been broken.
