OPERATION MANUAL

1. SAFETY INFORMATION

The following safety information must be observed to insure
maximum personal safety during the operation at this meter.
1.1 Do not operate the meter if the body of meter or the test lead
look broken.
1.2 Check the main function dial and make sure it is at the correct
position before each measurement.
1.3 Do not perform resistance, temperature, diode and continuity
test on a live power system.
1.4 Do not apply voltage between the test terminals and test
terminal to ground that exceed the maximum limit
this manual.
1.5 Exercise extreme caution when measuring live system with
voltage greater than 60V DC or 30V AC.
1.6 Keep the fingers after the protection ring when measuring
through the test lead.
1.7 Change the battery when the symbol appears to avoid incorrect
data.
