Safety & Warnings
The manual includes several safety warnings and precautions:
1. Do not exceed the specified input ratings to prevent personal injury or damage to the instrument.
2. Never use the clamp meter unless the battery compartment is closed.
3. Remove test leads before replacing the battery.
4. Always remove test leads when they are not in use to avoid danger.
5. Use only the safety type test leads supplied with the clamp meter.
6. Turn off equipment while making test connections in high voltage circuits and discharge high voltage capacitors after removing power.
7. For safe voltage measurement in high voltage equipment, do not touch equipment, meter, or test leads while power is applied.
8. Familiarize yourself with the equipment or system being tested and the location of its high voltage areas.
9. Use an insulated floor material or floor mat to stand on, ensuring surfaces are not damp or wet.
10. Keep one hand in the pocket while handling an instrument probe to avoid contact with nearby metal objects that could provide a ground return path.
11. When using a probe, touch only the insulated portion and never the exposed tip.
12. Never assume connections designated as “neutral” are at ground potential.
13. Ensure any ground is acceptable before relying on it.
14. Never assume circuit power is off until certain.
15. Never work alone; someone should be nearby to render aid if necessary, with training in CPR and first aid highly recommended.
