4. If the resistance is less than approx 150 Ω, the audible
signal will sound. If the circuit is open, the display will
indicate “OL”.
5.8. Diode Measurement
1. Set the function switch to the Ω / /
°
))) position.
2. Press the MODE-button to indicate on the display.
3. Touch the test probes to the diode under test. Forward
voltage will typically indicate 0,400 to 0,700 V. Reverse
voltage will indicate “OL”. Shorted devices will indicate near
0 V and an open device will indicate “OL” in both polarities.
Note:
1. When the input is not connected, i. e. at open circuit, the
figure "OL" will be displayed for the overrange condition.
2. There is 1 mA Current flow through the device under test.
3. The meter displays the forward voltage drop in millivolts and
over-load when the diode is reversed.
5.9. MAX Hold button
To hold the highest reading on the LCD:
1. Press the MAX hold button. The meter reading will not
change as readings change
2. Press the MAX hold button again to return to normal
operation.
