INTRODUCTION
This meter is a compact 3 3/4-digit digital automotive multimeter. In addition to the features ofa normal multimeter, it can also be
used to measure RPM, dwell angle, duty cycle, internal resistance of vehicle battery, temperature °C/°F, and etc. It is a useful, ideal
measurement tool for automotive repair and service.
It can be used to measure :
1. RPM of engine
2. Dwell angle
3. Internal resistance of vehicle battery
4. Duty cycle
5. DC and AC voltage
6. DC and AC current
SAFETY INFORMATION
This meter has been designed according to IEC-61010 concerning electronic measuring instruments with a measurement category
(CAT III 600V) and Pollution degree 2.
Warning
To avoid possible electric shock or personal injury, followthese guidelines:
Do not use the meter if it is damaged. Before you use the meter, inspect the case. Pay particular attention to the insulation surrounding
●
the connectors.
Inspect the test leads for damaged insulation or exposed metal. Check the test leads for continuity. Replace damaged test leads before
●
you use the meter.
Do not use the meter if it operates abnormally. Protection may be impaired. When in doubt, have the meter serviced.
●
Do not operate the meter around explosive gas, vapor, or dust. Don't use it under wet condition.
●
Do not apply more than the rated voltage, as marked on the meter, between terminals or between any terminal and earth ground.
●
Before use, verify the meter's operation by measuring a known voltage.
●
When measuring current, turn off circuit power before connecting the meter in the circuit. Remember to place the meter in series with
●
the circuit.
When servicing the meter, use only specified replacement parts.
●
Use caution when working with voltage above 30V ac rms, 42V peak, or 60V dc. Such voltages pose a shock hazard.
●
When using the probes, keep your fingers behind the finger guards on the probes.
●
When making connections, connect the common test lead before you connect the live test lead. When you disconnect test leads,
●
disconnect the live test lead first.
Remove the test leads from the meter before you open the battery cover or the case.
●
Do not operate the meter with the battery cover or portions of the case removed or loosened.
