4.
If the resistance is less than approx 150
, the audible signal will
sound. If the circuit is open, th
e display will indicate “OL”.
5.10. Diode Measurement
1.
Set the function switch to the
/
/
°
))) 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 in
dicate 0,400 to 0,700V. Reverse voltage will indicate “OL”.
Shorted devices will indicate near 0V 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.
5.11. HOLD-Button
The DATA-HOLD func
tion allows the meter to “freeze” a measurement for
later reference.
1.
Press the “HOLD”-button to freeze the display, the “HOLD” indicator
will appear.
2.
Press the “HOLD”-button to return to normal operation.
5.12. Flashlight
Press and hold the “
“-button to turn the flashlight on. Release the button
to turn the flashlight off.
