WARNING
• The maximum rated voltage between input terminals
and the ground is as follows;
(CAT II): 300 V rms
(CAT III): 150 V rms
(CAT IV): 100 V rms
Attempting to measure voltages exceeding this
level with respect to ground could damage the
instrument and result in personal injury.
• To avoid electric shock, be careful to avoid shorting
live lines with the test leads.
