3. Open the circuit to be measured, and connect test leads IN SERIES
with the load in which current is to be measured.
4. Read current value on Digital Display.
RESISTANCE MEASUREMENT
1. Red lead to "V
Ω
mA". Black lead to "COM".
2. RANGE switch to desired
Ω
Position.
3. If the resistance being measured is connected to a circuit, turn off
power and discharge all capacitors before measurement.
4. Connect test leads to circuit being measured.
5. Read resistance value on Digital Display.
DIODE MEASUREMENT
1. Red lead to "V
Ω
mA". Black lead to "COM".
2. RANGE switch to position.
3. Connect the red test lead to the anode of the diode to be measured
and the black test lead to the cathode.
4. The forward voltage drop in mV will be displayed. If the diode is
reversed, figure "1" will be shown.
TRANSISTOR hFE MEASUREMENT
1. RANGE switch to the hFE position.
2. Determine whether the transistor is NPN or PNP type and locate the
Emitter, Base and Collector leads. Insert the leads into the proper holes
of the hFE Socket on the front panel.
3. The meter will display the approximate hFE value at the condition of
base current 10
μ
A and VCE 2.8V.
TEMPERATURE MEASUREMENT
1. Connect the K type thermocouple to "V
Ω
mA" and "COM".
2. RANGE switch to TEMP position.
3. The display will read the temperature value
℃
.
AUDIBLE CONTINUITY TEST
1. Red lead to "V
Ω
mA". Black lead to "COM".
2. RANGE switch to
