damage of the instrument, do not
measure voltages that might exceed 500V
above earth ground.
Before the use of instrument, inspect test
leads, connectors and probes for cracks,
breaks, or crazes in the insulation.
DC & AC VOLTAGE MEASUREMENT
1. Connect red test lead to “V Ω mA” jack, Black
lead to “COM” jack.
2. Set RANGE switch to desired VOLTAGE
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.
DC CURRENT MEASUREMENT
1. Red lead to “V Ω mA”. Black lead to “COM”
(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
