1. SUMMARY
This 3 5/6 Digit Highly Stable clamp meter uses two AAA (1.5V) batteries. It has a LCD with 18mm
digit display, which makes the reading clearer and the operation more convenient. It can test DCV, ACV,
DCA, ACA, resistance, capacitance, frequency, temperature, diode, continuity, as well as non-contact
AC voltage test. It is equipped with clamp jaw lighting, Backlight, unit symbol display, True RMS, data
hold function, Relative measurement, auto power off and warning functions. It works in both auto range
and manual range. To assure high accuracy and resolution, it adopts a micro-processor which drives the
LCD directly and a dual integral A/D converter IC. It is an ideal tool for labs, factories radio-technology
and household.
2. SAFETY NOTICE
The instrument is designed according to IEC1010-1 standard (safety standard issued by International
Electro technical Committee), CAT III 600V and UL3111-1. Please read the followings carefully before
any operation.

battery indication.
2. Notice:
(1) Please disconnect any signal and pluck out the test leads before opening the outside cover.
(2) To avoid electric shock and damage to the meter, water should not be leaked inside.
(3) DO NOT use this meter to do any test if the case hasn't finished installation and its screws haven't
been tightened.
(4) DO NOT input the value higher than the limit at every range.
(5) Please don't input voltage in resistance terminal.
(6) Please turn the power switch to OFF after the test.
(7) To avoid the damage of battery leakage to the meter, please remove the battery for long-term storage.
(8) To avoid electric shock and damage to the meter, do not input voltage higher than DC 60V or AC
36V during the measurement.
(9) To avoid electric shock, please be seriously careful when nipping the bus bar or something insulated.
