Never apply a voltage to the multimeter that exceeds 1000VDC or 700VAC rms between an input jack and
ground.
•
Use extreme caution when working with voltages above 60VDC or 30VAC rms.
•
Always discharge the filter capacitors in the power supply circuit under test before attaching the test leads.
•
Never connect a voltage source to the DVM830L when the device is in the DCA, ACA, resistance continuity
mode.
•
Always turn off the power and disconnect the test leads before replacing the battery or fuse.
•
Never operate the multimeter unless the battery cover is in place and fully closed.
When carrying out measurements on TV's or switching power circuits, always remember that there may be high
amplitude voltage pulses at test points which may damage the meter.
