Operation
Please Notice:
•
When taking measurements in the range under 2 M Ω it can take several
seconds before a stable value is reached.
•
If the measuring range is exceeded, a “1” is displayed as overflow
indicator.
•
Keep the measuring tips clean to ensure a good connection.
Accuracy
Range Resolution Accuracy
20 K Ω 1 Ω ± 1 % of Measured Value + 1 Digit
2 M Ω 100 Ω ± 1 % of Measured Value + 1 Digit
Diode Test Function
With this function you can test diodes and other semiconductors for continuity
and blocking function. The continuity current is 1.2 mA.
Attention!
•
Never connect the measuring tips with a power source while using this
function; this can lead to the destruction of the unit.
•
Only take measurements on circuitry which is disconnected from all power
sources and additionally make sure all capacitors are discharged.
Measuring Procedure
•
Connect the black measuring cable to the COM input (7) and the red
measuring cable to the V/ Ω input (6).
•
Set the rotary function switch (4) to .
•
Connect the measuring cables to the component you intend to check and
read the value from the display.
Please Notice:
•
Connect the red measuring cable to the anode (The end of the diode not
marked with a ring) and the black measuring cable to the cathode.
