Warning
Do not exceed the meter's voltage or current limits.
Use caution when testing voltages higher than
50VAC or 110VDC.
Do not use if the meter or test leads are damaged.
Remove test leads before replacing the battery
or fuse.

Operating Instructions

Controls

The 'ON/OFF' switch is used to turn the meter
'ON'. To conserve battery power, always turn the
meter 'OFF' when not in use.
The parameter to be measured is selected using the
rotary 'Function' switch.
For accuracy make sure the correct range is used.
When the display shows '1' this indicates an
over-range reading, use the next highest range.

Connecting Test Leads

There are three connection jacks, marked:
1. 10ADC
2. VΩmA
3. COM
The BLACK test lead should be placed in the
'COM' jack.
For most measurements, except current over
200mA the RED test lead should be placed in
the 'VΩmA' jack.
For current over 200mA but less than 10A the RED
test lead should be placed in the '10ADC' jack.

Measuring DC Voltage

1.Connect the RED test lead to the 'VΩmA'
jack and the BLACK test lead to the 'COM' jack
2.Set the Function switch to the correct
'DCV' range.
3.Turn the meter 'ON'
4.Connect the test probes across the Voltage
to be measured.
