When you use this function, through the testing element circulates a
1mA current, approximately.
The voltage in direct polarization is displayed in mV, in inverted
polarization the LCD screen will display “1”.
Transistor measurement –hFE-
1.-
Set the dial to the hFE range.
2.-
Determine if the transistor is NPN or PNP and localize the emitter, base,
and collector.
3.-
The meter will show the approximate hFE value with base current condi-
tion of 10 uA and VCE 2.8 V.
Measuring audible continuity
To avoid tester’s or proof devices’ damage, disconnect circuit’s power and
discharge all high voltage capacitors before continuity test.
1.- Connect the red testing point in the jack signaled VΩmA and the black
testing point in the jack signaled COM.
2.- Set the dial to
.
3.- Connect the testing points on the circuit to be measured.
4.- The measured value will show on the screen.
5.- If the resistance is less than 30 Ω the meter will sound.
