Safety & Warnings
An electrical shock causing 10 milliamps of current to pass through the heart will stop most human heartbeats. Voltage as low as 35 volts DC or AC rms should be considered dangerous and hazardous since it can produce a lethal current under certain conditions. Higher voltages are even more dangerous. Observe the following safety precautions:
1. Never exceed the following input ratings to avoid the possibility of personal injury and/or damage to the instrument:
– DC VOLTS 1000V DC
– AC VOLTS 750V rms
– AMPS 1000A DC or AC rms
– OHMS, FREQ., CAP, DIODE TEST 500V DC or AC rms
2. Before using the clamp meter, verify that the battery compartment of the instrument is intact. Never use it with this compartment open.
3. Before taking measurements, inspect the meter, test leads, and any accessories to make sure they are in good condition. Replace any defective items. Only use safety type test leads.
4. When using a probe, touch only the insulated portion. Never touch the exposed tip.
5. For your safety when making high voltage measurements while the power is on, never touch the equipment, meter, or test leads.
6. The insulation rating of the clamp is 500V. Do not clamp around conductors at higher voltages.
7. Use the time-proven “one hand in the pocket” technique while handling an instrument probe. Be very careful to avoid contacting a nearby metal object that could provide a good ground return path. Never ground yourself when taking a measurement.
8. If possible, familiarize yourself with the equipment being tested and the location of its high voltage points. Remember that high voltage may appear at unexpected points in defective equipment.
9. Never try to service this meter unless you have been properly trained. Service must only be carried out by qualified and trained technicians.
10. Before replacing batteries, make sure that the input leads are disconnected from any voltage points and removed from the meter.
11. Never work alone. Someone should be nearby to render aid if necessary. Training in CPR (cardio-pulmonary resuscitation) first aid is highly recommended.
