IV. Electrical Symbols
1. Before use, please check if there is any item which is damaged or behaving
abnormally. If any abnormal item (such as bare test lead, damaged meter
casing, broken LCD, etc.) is found, or if the meter is considered to be
malfunctioning, please do not continue to use the meter.
2. Do not use the meter if the rear cover or the battery cover is not completely
covered up, it may pose a shock hazard!
3. When using the meter, keep fingers behind the finger guards of the test leads,
and do not touch exposed wires, connectors, unused inputs, or circuits being
measured to prevent electric shock.
4. The function dial should be placed in the correct position before measurement.
5. Do not apply voltage over 1000V between any meter terminal and earth ground
to prevent electric shock or damage to the meter.
6. Use caution when working with voltage above AC 30Vrms, 42Vpeak or DC
60V. Such voltages pose a shock hazard.
7. Never input voltage or current which exceeds the specified limit. If the range
of the measured value is unknown, the maximum range should be selected.
8. Before measuring the resistance, diode and continuity , switch off the power
supply of the circuit, and fully discharge all capacitors to avoid inaccurate
measurement.
9. When the “ ” symbol appears on the LCD, please replace the batteries in
time to ensure measurement accuracy. If the meter is not in use for a long
time, please remove the batteries.
10.Do not change the internal circuit of the meter to avoid damage to the meter
and user!
11.Do not use or store the meter in high temperature, high humidity, flammable,
explosive or strong magnetic field environments.
12.Clean the meter casing with a soft cloth and mild detergent. Do not use
abrasives or solvents!

AC Current Measurement
1)
2)
Turn the function dial to A~ position.
Press the trigger to open clamp jaws and fully enclose one conductor (only
one conductor can be measured at a time). For optimum results, center the
conductor in the jaws.
Current Frequency Measurement
1) When the function dial is in the AC current position, short press the Hz button
to enter the frequency measurement mode.
2) Short press the Hz button again to exit the frequency measurement mode.
