Shock or damage of clamp meter.
6. To operate the instrument carefully under DC 60V
or AC 30V to avoid electric shock.
7. Do not measure voltage or current which is more
than permissible input value. Be sure to place
function range switch to the maximum range
position if scope of measured value cannot be
determined. Be sure to cut off circuit power and
discharge all capacitors before ON/OFF
measurement of online resistance, diode or
circuit. To disconnect probe and measured circuit
then remove probe from input end of clamp meter
and cut off power after measurement.
8. To replace battery in a timely manner during
display of LCD display to guarantee high
measurement precision. To take battery out if
clamp meter has not been used for a long time.
9. Please do not alter internal wiring of clamp meter
randomly to avoid instrument damage and safety
danger.
10.Do not store or use clamp meter in environment
in high-temperature, high-humidity, combustible,
explosive and strong current magnetic environment.
11.Please clean the instrument shell by soft cloth
and neutral detergent during maintenance. Do
not use abrasive or solvent to avoid shell
corrosion which may cause instrument damage
and safety danger.

1. Input end;
2. LCD digit display;
3. Function key: To select basic functions;
4. Measurement function knob: White mark is
initially set value; Blue mark is validated after
selecting blue key;
5. Clamp head trigger: To press the trigger to
loosen clamp head. Clamp head will be tightened
again locally if loosening the trigger;
6. Hand protection: It is designed to guarantee
safety when hand of users touching dangerous
zone;
7. Clamp head: It is a device to measure AC/DC
current to convert current to voltage. Single
conductor of measured current must pass through
center of clamp head perpendicularly;
