OPERATION INSTRUCTIONS
WARNING
1. To avoid electrical shock hazard and / or damage of the instrument, do not measure voltages that
might exceed 250V above earth ground.
2. Before the use of instrument, inspect test leads, connectors and probes for cracks, breaks, or
crazes in the insulation.
DC VOLTAGE MEASUREMENT
1. Connect red test lead to «V Ω mA» jack. Black lead to «COM» jack.
2. Set RANGE switch to desired DCV position. If the voltage to be measured is not known beforehand,
set switch to the highest range and reduce it until satisfactory reading is obtained.
3. Connect test leads to device or circuit being measured.
4. Turn on power of the device or circuit being measured, voltage value will appear on Digital Display
along with the voltage polarity.
AC VOLTAGE MEASUREMENT
1. Red lead to «V Ω mA» jack . Black lead to «COM» jack.
2. RANGE switch to desired ACV position.
3. Connect test leads to device or circuit being tested.
4. Read voltage value on Digital Display.
DC CURRENT MEASUREMENT
1. Red lead to «V Ω mA» jack. Black lead to «COM» jack. (For measurements between 200mA and 10A
connect red lead to «10A» jack with fully depressed.)
2. RANGE switch to desired DCA position.
3. Open the circuit to be measured, and connect test leads INSERIES with the load in which current is
to be measured.
4. Read current value on Digital Display
*In 10A range, measure time can’t exceed 10 second.
RESISTANCE MEASUREMENT
1. Red lead to «V Ω mA» jack. Black lead to «COM» jack
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
