HEALTH & SAFETY INFORMATION

This instrument complies with IEC1010 (International Electrotechnical Commission promulgated safety standards). Design and production with an over- voltage category (CAT III) and using the pollution level 2 safety requirements.

Warning

To avoid electrical shock or personal injury. Please read the safety information and “warnings and precautions” before use. When measuring voltage above 30V, current above 10ma, AC power with an inductive load. Use caution not to touch exposed contacts due to the risk of electric shock, only use approved probes or clamps.

1. Before measuring, check whether the measurement function switch is in the correct position, check whether the test probe is connected correctly to avoid electric shock.
2. The meter is only to be used in conjunction with the supplied test leads to comply with safety standards.
3. If the test leads are broken or damaged, replace the test leads of the same type or the same electrical specifications.
4. Do not use an unapproved fuse to replace the fuse inside the meter.
5. Only replace with the same model or the same specifications of the fuse.
6. Before changing, remove the test leads to ensure that there is no signal input.
7. Do not use unapproved batteries to replace the battery inside the meter.
8. Replace only with the same model or the same electrical specifications of the battery.
9. DO NOT mix new and old batteries and do not use re-chargeable batteries.
10. Before changing, remove the test leads to ensure that there is no signal input.
11. During electrical measurements, the body must not be directly in contact with the earth, use insulating materials to keep your body insulated from the earth.
12. Do not store or use in high temperature, high humidity, flammable, explosive and strong magnetic field environments.
13. Measurements exceeding the limit values of the instrument may damage the instrument and endanger the safety of the operator.
14. Do not attempt to calibrate or service the instrument.
