• When working above 30 V
poses a shock hazard.
• Do not measure more than the rated current and voltage (as marked on the
clamp meter).
• Ensure the test leads are disconnected from the input terminals when
measuring current with the clamp meter. Keep your fingers behind the hand
guard when performing measurements.
• When connecting probes, always connect the common test probe first. When
disconnecting probes, always disconnect the live test probe first.
• Detach test probes from the clamp meter before you open the battery cover.
• Do not use the clamp meter with the battery cover or part of the cover removed
or loose.
• Replace the battery as soon as the low battery indicator is shown on the
annunciator display. This is to avoid false readings, which may lead to possible
electric shock or personal injury.
• When measuring temperature, keep the thermocouple probe as close to the
meter as possible, and avoid contact with surface above 30 V
as this will pose shock hazard.
• Do not operate the product in an explosive atmosphere or in the presence of
flammable gases or fumes.
• Inspect the case for cracks or missing plastic. Pay extra attention to the
insulation surrounding the connectors. Do not use the clamp meter if it is
damaged.
• Inspect the test probes for damaged insulation or exposed metal, and check for
continuity. Do not use the test probe if it is damaged.
• Do not service or perform adjustments alone. Under certain condition,
hazardous voltages may exist, even with the equipment switched off. To avoid
dangerous electric shock, service personnel must not attempt internal service
or adjustment unless another person, capable of rendering resuscitation or first
aid, is present.
