Built-In Buzzer
1. When you press a button, the built-in buzzer will sound a beep if the
press is effective.
2. The buzzer will sound several short beeps about one minute before
the meter turns off automatically and sound long beep before the
meter turns off automatically.
3. The buzzer will sound and the display will show "OL" in one of the
following conditions:
a. The AC voltage under measurement is more than about 600V ac
when the meter is in the highest AC voltage range.
b. The DC voltage under measurement is more than about 600V dc
when the meter is in the highest DC voltage range.
c. The DC current under measurement is more than about 10A dc
when the meter is in the highest DC current range.
d. The AC current under measurement is more than about 10A ac
when the meter is in the highest AC current range.
Measuring DC or AC Voltage
1. Connect the black test lead to the "COM" terminal and the red test
lead to the "
2. Set the range switch to the "
measurement or to the "
3. Select autorange mode or manual range mode with the "RANGE"
button.
If you use manual range mode and don't know the magnitude of the
voltage to be measured beforehand, select the highest range and then
reduce it range by range until satisfactory resolution is obtained.
4. Connect the test leads across the source or circuit to be measured.
5. Read the output on the display. For DC voltage measurements, the
polarity of red lead connection will be indicated as well.
Note: To avoid electric shock to you or damages to the meter, never
apply a voltage higher than 600V between the terminals.
Measuring DC or AC Current
1. Connect the black test lead to the "COM" terminal. If the current to
be measured is less than 400mA, connect the red test lead to the "µA/
mA" terminal. If the current is between 400mA and 10A, connect the
red test lead to the "10A" terminal instead.
2. Set the range switch to desired
3. Press the "S" button to select DC current or AC current
measurement, the display will show the corresponding symbol.
4. Turn off power to the circuit which you want to measure. Then
discharge all high voltage capacitors.
5. Break the circuit path to be measured, then connect the test leads in
series with the circuit.
6. Turn on power to the circuit, then read the display. For DC current
measurements, the polarity of the red test lead connection will be
indicated as well.
Note: If the magnitude of the current to be measured is not known
beforehand, select the highest range and then reduce it range by
