DC & AC Voltage Measurement
1. Set Function switch to (DCV) or (ACV), and the rotary switch to desired VOLTAGE range, if the voltage to be measured is not
known beforehand, set switch to the highest range and reduce it until satisfactory reading is obtained.
2. Connect test leads to device or circuit being measured.
3. Turn on power of the device or circuit being measured voltage value will appear on Digital Display along with the voltage polarity.
DC Current Measurement
1. Set Function switch to , and the rotary switch to 200mA.
2. Connect the test leads in series with the test load whose current is to be measured.
3. Read the current value on Digital Display.
Resistance Measurement
1. Set Function switch to Ω, and the rotary switch to desired OHM range.
2. If the resistance being measured is connected to a circuit, turn off power and discharge all capacitors before measurement.
3. Connect test leads to circuit being measured.
4. Read the resistance value on Digital Display.
Diode Measurement
1. Set Function switch to Ω, and the rotary switch to .
2. Connect the red test lead to the anode of the diode to be measured and black test lead to cathode.
3. The forward voltage drop in mV will be displayed. If the diode in reverse polarity, the screen will display “1”.
Audible Continuity Test
1. Set Function switch to Ω, and the rotary switch to .
2. Connect test leads to two points of the circuit to be tested. If the resistance is lower than 30Ω±20Ω, the buzzer will sound.
