capacitors.
l Open-circuit voltage of continuity
measurement is about 3V.
l When continuity testing has been
completed, disconnect the connection
between the testing leads and the circuit
under test.
F. Power Voltage measurement(see figure 8)
Warning
To avoid damage to the inside fuse and the
Meter, please do not attempt using battery
and power of any other specification to
measure except prescribed as Note.
The measure the power voltage, connect the
Meter as follows:
1. Insert the red test lead into theµA
mA terminal and the black test lead
into the COM terminal.
2. Set the rotary switch to , place the red test
lead on the anode of the power under test
and place the black test lead on the cathode
of the power under test.
3. The measured value shows on the display.
Note
l The range of 1.5V only fit for the measure
of 1.5V Battery, inside load resistance is
38O.
