beyond a CAUTION notice until the indicated conditions are fully understood and met.
Use the meter only as specified in this guide. Otherwise, the protection provided by the meter may be impaired.
Refer to the safety information below:
• When working above 70V DC, 33 V AC RMS or 46.7 V peak, exercise caution – such range pose a shock
hazard.
• Do not measure more than the rated voltage (as marked on the meter) between terminals, or between terminal
and earth ground.
• Double-check the meter’s operation by measuring a known voltage.
• For current measurement, turn off circuit power before connecting the meter to the circuit. Always place the
meter in series with the circuit.
• 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 meter before you open the battery cover.
• Do not use the meter with the battery cover or part of the cover removed or loose.
• Replace the battery as soon as the low battery indicator flashes on screen. This is to avoid false readings,
which may lead to possible electric shock or personal injury.
• Do not operate the product in an explosive atmosphere or in the presence of flammable gases or fumes.
