- 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 measuring device off. Turn the rotary switch to „OFF“.
☞
If you carry out a resistance measurement, make sure that the measur-
ing points which you contact with the test prods are free from dirt, oil, sol-
derable lacquer or the like. An incorrect measurement may result under
such circumstances.
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.
- Turn the measuring device on at the rotary switch and select measuring range
.
- Plug the measuring lines into the measuring device as specified under Item Resis-
tance measurement.
- Select the diode test function with the MODE button (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 measuring device off. Turn the rotary switch to „OFF“.
