Battery Measurement; Battery And Fuse Replacement - General DMM20 Manual De Usuario

3. If the resistor to be measured is connected to a circuit,
disconnect circuit power and discharge all capacitors
before measuring resistance.
4. Connect the test leads across the resistor to be
measured and read the resistance value on the LCD
display.
DIODE & CONTINUITY MEASUREMENT
1. Connect the red test lead to the "V
black test lead to the "COM" jack.
2. Set the range switch to the
3. Connect the red test lead to the anode of the diode to
be tested and the black test lead to the cathode of the
diode.
4. The approximate forward voltage drop of the diode will
be displayed in mV. If the connection is reversed, only
figure "1" will be shown on the LCD.
5. Connect the test leads to the two terminal of the circuit
to be tested. If the resistance is lower than about 50 ,
the built-in buzzer will sound.

BATTERY MEASUREMENT

1. Set the range switch to the desired "BATT" range
(1.5V or 9V).
2. Connect the red lest lead to the "V
black test lead to the "COM" jack. Connect the test
leads to the two terminals of the battery to be
measured and read the value on the LCD display.

BATTERY AND FUSE REPLACEMENT

If the sign "BAT" or "
indicates that the battery should be replaced. If the error
of the reading is too much, it also indicates that the
battery should be replaced. To replace the battery, loosen
the screws on the back cover and open the case. Replace
the exhausted battery with a new one of the same type.
The fuse rarely needs to be replaced and is blown as a
