4. Once the reading stabilizes, read the value. If the polarity is twisted a "Minus
sign" is displayed. Use the HOLD function if the reading is difficult to read.
5. If the resistance is less than about 150Ω, you hear an audible signal. If the
circuit is open, the display shows "OL".
Contactless voltage detector
1. This feature is available in each switch position.
2. Hold the upper part of the instrument as close as possible to the power
source.
3. If a voltage is applied, the red LED lights on top of the screen.
Diode testing
Set the rotary switch to the - Position.
1.
2. Attach the pin-plug of the black test lead to the COM-jack and the pin-plug of
the red test lead to the V-, A-, Ω-jack.
3. Touch the diode to be tested with the probes. The forward voltage shows 400
to 700mV. The counter voltage shows „OL". Defective devices show a value
about 0 mV or „OL" in both polarities.
HOLD Function
If the reading could not be read during measurement due to difficult operation the
„HOLD"-button could be pressed to freeze the display reading.
1. Press the „HOLD"-button to freeze the display reading.
2. The display shows the „HOLD"-symbol to indicate the activated HOLD function.
3. Press the „HOLD"-button again to return to standard operation.
