OPERATING INSTRUCTION
Voltage Measurement
1. Set rotary switch to the V range.
2. Press the
SELECT key to select DCV or ACV measuring mode.
3. Connect the black and red test leads to the circuit being measured
4. Read the displayed value. The polarity of red test lead connection
will be indicated when making a DCV measurement.
Current Measurement
1. Turn off power to the circuit. Discharge all high voltage capacitors.
2. Set the rotary switch to the mA range.
3. Press the
SELECT key to select DCA or ACA measuring mode.
4. Break the circuit path to be tested.
Touch the black probe to the more negative side of the break; touch
the red probe to the more positive side of the break. (Reversing the
leads will give a negative reading, but will not damage the Meter.)
6. Turn on power to the circuit; then read the display.
7. Turn off power to the circuit and discharge all high voltage capacitors.
Remove the Meter and restore the circuit to normal operation.
Capacitance Measurement
1. Set the rotary switch to range.
2. Connect the test leads to the capacitor being measured and read
the displayed value.
