2.2 Voltage Measurement
• The maximum input voltage is 1000 VDC,
1000 Vrms, or 10
7
V•Hz.
Attempting to measure voltage in excess
of the maximum input could destroy the
product and result in personal injure or
death.
• To avoid electrical shock, be careful to
avoid shorting live lines with the test leads.
• For safety, test lead connections must
always be made at the secondary side of a
circuit breaker.
• The maximum rated voltage between input
terminals and ground is 1000 VDC/AC (CAT-
III), 600 VDC/AC (CATIV), or 10
7
V•Hz.
Attempting to measure voltages exceeding
this limit with respect to ground could dam-
age the product and result in personal
injury.
