Safety Information
WARNING
Understand and follow operating instructions carefully.
• Remove test lead from Meter before opening the battery
door or Meter case.
protection by the Meter might be impaired.
• Always use proper terminals, switch position, and range
for measurements.
• Never attempt a voltage measurement with the test lead
inserted into the A input terminal.
• Verify the Meter’s operation by measuring a knownvoltage.
If in doubt, have the Meter serviced.
• Do not apply more than the rated voltage, as marked on
Meter, between terminals or between any terminal and
earth ground.
• Do not attempt a current measurement when the open
voltage is above the fuse protection rating.Suspected
open circuit voltage can be checked with voltage function.
• Only replace the blown fuse with the proper rating as
• Use caution with voltages above 30 Vac rms, 42 Vac peak
or 60 Vdc. These voltages pose a shock hazard.
• To avoid false readings that can lead to electric shock and
injury, replace battery as soon as low battery indicator <appears.
• Disconnect circuit power and discharge all highvoltage
capacitors before testing resistance, continuity, diodes, or
capacitance.
• Do not use Meter around explosive gas or vapor.
