1.Safety Information
Be sure to read the safety information before using this product.
General Safety Requirements
Before any operations, please read the following safety precautions to avoid any possible bodily injury and prevent this product or any other products connected from damage. In order to avoid any contingent danger, this product is only used within the range specified. Limit operation to the specified measurement category, voltage, or amperage ratings. Do not use the digital clamp meter if it is damaged. Before you use the digital clamp meter, inspect the case. Look for cracks or missing plastic. Pay particular attention to the insulation surrounding the connectors. Do not use the test leads provided for other products. Use only the certified test leads specified for this product. Inspect the test leads for damaged insulation or exposed metal. Before use, verify the digital clamp meter’s operation by measuring a known voltage. Only the qualified technicians can implement the maintenance. Always use the specified battery type. The power for the digital clamp meter is supplied with a battery. Observe the correct polarity markings before you insert the batteries to ensure proper insertion of the batteries in the digital clamp meter. Check all Terminal Ratings. To avoid fire or shock hazard, check all ratings and markers of this product. Refer to the user’s manual for more information about ratings before connecting to the digital clamp meter. Do not operate the digital clamp meter with the cover or portions of the cover removed or loosened. Do not operate if in any doubt. If you suspect damage occurs to the digital clamp meter, have it inspected by qualified service personnel before further operations. Do not operate this product in wet or damp conditions.

1.Safety Information
Do not operate in an explosive atmosphere. Keep product surfaces clean and dry. Do not apply more than the rated voltage (as marked on the digital clamp
meter) between terminals, or between terminal and earth ground. When measuring current, turn off the circuit power before connecting the
digital clamp meter in the circuit. Remember to place the digital clamp meter in series with the circuit. When servicing the digital clamp meter, use only the specified replacement parts. Use caution when working above 60 V DC, 30 V AC RMS, or 42.4 V peak. Such voltages pose a shock hazard. When using the test leads, keep your fingers behind the finger guards on the test leads. Remove the test leads from the digital clamp meter before you open the battery cover. To avoid false readings, which may lead to possible electric shock or personal injury, replace the battery as soon as the low battery indicator appears and flashes. Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, diodes, or capacitance. Use the proper terminals, function, and range for your measurements. When the range of the value to be measured is unknown, set the rotary switch position as the highest range, or choose the auto ranging mode. To avoid damages to the digital clamp meter, do not exceed the maximum limits of the input values shown in the technical specification tables. Connect the common test lead before you connect the live test lead. When you disconnect the leads, disconnect the live test lead first. Before changing functions, disconnect the test leads from the circuit under test.

1.Safety Information
Measurement Category
The digital clamp meter has a safety rating of 1000 V,CAT III and 600V,CAT IV.
Measurement category definition
Measurement CAT I applies to measurements performed on circuits not directly connected to the AC mains. Examples are measurements on circuits not derived from the AC mains and specially protected (internal) mainsderived circuits.
Measurement CAT II applies to protect against transients from energy-consuming equipment supplied from the fixed installation, such as TVs, PCs, portable tools, and other household circuits.
Measurement CAT III applies to protect against transients in equipment in fixed equipment installations, such as distribution panels, feeders and short branch circuits, and lighting systems in large buildings.
Measurement CAT IV applies to measurements performed at the source of the low-voltage installation. Examples are electricity meters and measurements on primary over current protection devices and ripple control units.

3.Appendix
Charging and Replacement of Battery
During the long-term storage of the device, the battery may be too low due to the self-discharge of the lithium battery and the device cannot be turned on. T his is a normal phenomenon. Please use the attached adapter to pre-charge the device for 0.5 to 1 hour ( depending on the storage time) before turning it on. In addition, if the device is not used for a long time, it is recommended to charge it at regular intervals to avoid over-discharge of the lithium battery.
Battery Charging The lithium battery may not be fully charged when delivered. To make the battery be charged,this device has an approximate charging time of 8 hours and a peak discharge battery life of about 18.5 hours.The power supply and battery indicator symbols in the upper right corner of the screen are explained as follows: symbol indicates the power-on charging status; symbol indicates battery power supply; symbol indicates that there is only about five minutes of use time left.
Please charge as soon as possible according to the relevant tips to avoid damage to the battery.
Charging Method
Connect the digital clamp meter to a computer or other equipment through a USB data cable for charging (pay attention to the load capacity of the power supply equipment to avoid abnormal operation of the equipment). Note
To avoid overheating of the battery during charging, the ambient temperature must not exceed the allowable value given in the technical specifications.
Replacement of Lithium Battery
Generally, the battery does not need to be replaced. However, when necessary, it can only be replaced by qualified personnel, and only lithium batteries of the same specification can be used.
