3.Safety Operation Specification Warning: To avoid such possible safety accidents as electric shock or bodily injury, please strictly observe the following guidelines: Prior to the use of the instrument, please carefully read the manual, and pay special attention to the related safety warning information herein. The instrument shall be used in stringent conformity to the instructions contained herein, or else the protection function supplied by the instrument may be impaired or damaged.
To make measurement, connect the zero line or ground line, and then the firing line; to finish measurement, disconnect the firing line, and then the zero line and ground line. Before opening the outer casing or battery cover, remove the pen from the instrument.
CAT IV measurement is applicable for testing and CAT IV measuring circuits connecting to the distribution section 600V of building low voltage power supply. 5.Overview This instrument is a smart digital flexible clamp meter. It can be used for measuring the direct voltage, alternating voltage, alternating current, frequency, resistance and connectivity.
Power off: with the device in the on state, press the button, and keep it pressed, until the buzzer produces the sound “di”. Auto Shut-down Function If no button is pressed, and no signal is input, the device will turn off automatically within five minutes.
AC Current Measurement 1) Press the power button to turn on the device; 2) Release the flexible clamp bonnet lock, allow the flexible clamp to go round the tested wire or conductor, insert the flexible clamp into the bonnet lock, and lock the bonnet lock (see the figure below);...

Minimum AC voltage measurement: 0.5V (AC); Input impedance: 2MΩ; Maximum input voltage: 600V DC or AC effective value; Frequency domain: 40Hz~2000Hz, true RMS. Other frequencies are not validated yet. Position Error of Flexible Clamp The precision and position error refers to the error of measurement taken at the best measuring position, within the range of working temperature and humidity, in the absence of interference from external electric field or magnetic field.
