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 use the meter.
Do notusethemeteriftherearcoverorthebatterycoverisnot

Keep fingersbehind the fingerguardsand awayfromthe metal
probe contacts when making measurements.
The function switch should be placed in the correct position before
measurement. It is forbidden to change the position during
measurement to avoid damage to the meter!
Do not apply voltage over 600V between any meter terminal and
earth ground to prevent electric shock or damage to the meter.
Use caution when working with voltages above AC 30Vr.m.s,
42Vpeak or DC 60V. Such voltages pose a shock hazard.
Never input voltage or current which exceeds the specified limit.
Maximum range should be selected if measured value is unknown.

9.5 NCV AC Electric Field Sensing (Picture 6a)
The electric field sensing sensitivity is divided into two levels
(“EFHI” and “EFLo”). The meter defaults to “EFHI”. Users can select
different sensitivity levels according to the intensity of the measured
electric field. Select "EFHI" of NCV when electric field is around 220V

field (socket, insulated wire, etc.). The LCD will display the segment

frequency of buzzer beeps and LED flashes. Select “EFLo” when the
electric field is around 110V
Caution:
Use the NCV sensing end to approach measured electric field,
otherwise the measurement sensitivity will be affected. When the

9.6 Others
Auto power off: The meter will automatically power off to save power
if there is no operation for 15 min. You can wake it up by pressing
any button or restart it after turning the switch to OFF.
Press and hold the SELECT button in off state and then turn on the
meter again to disable the auto power off function. Restart the meter
after shut it down to resume this function.
Buzzer: When any button is pressed or the function switch is turned,
if it is valid, the buzzer will make one beep (about 0.25s). The buzzer
will also beep intermittently to indicate the over range during the
voltage or current measurement.
Low battery detection: The battery voltage will be automatically
detected as long as the meter is on. If it is lower than 2.6V, the LCD
will display the “ ” symbol.
Low battery shutdown function: When the battery voltage is lower
than 2.5V, the LCD displays the “ ” symbol, the “Lo.bt” interface
appears and lasts for about 10s, the buzzer makes consecutive
beeps 3 times, and then the meter automatically shuts down (no

11.1 General Maintenance
Clean the meter casing with a soft cloth and mild detergent. Do
not use abrasives or solvents!
Do not use the tester or test leads if they appear to have any
abnormality.
The maintenance and service must be implemented by qualified
professionals or designated departments.
11.2 Battery Replacement (Picture 7)
When the “ ” symbol appears on the LCD, please replace the
batteries in time to ensure measurement accuracy. Batteries
specification:
2 standard AAA 1.5V batteries.
Operation
Turn off the meter and remove the test leads from the input terminals.
Unscrew the screw of the battery compartment, remove the battery
cover, and take out the used batteries as shown.
Replace the 2 standard AAA batteries according to the polarity
indication.

TESTING IN CAT III MEASUREMENT LOCATIONS
Ensure the test lead shield pressed firmly in place. Failure to use
the CAT III shield increases arc-flash risk.
TESTING IN CAT II MEASUREMENT LOCATIONS
CAT III shields may be removed for CAT II locations. This will allow
testing on recessed conductors such as standard wall outlets.
Take care not to lose the shields.
