2.1 Voltage Measurement
• The maximum input voltage is 1000 VDC,
1000 Vrms, or 10
7
V•Hz.
However, for CATIII circuits, the maximum
voltage is 600 Vrms. Attempting to mea-
sure voltage in excess of the maximum
input could destroy the product and result
in personal injury 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 V DC/AC
(CATII), 600 V DC/AC(CATIII), 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.
DC Voltage
Measurement
1. Move the functio
n
selector to the
V
position for AC mode o
r
to the V position fo
r
DC mode (in eithe
r
case, “V” lights up).
2. Connect the red tes
t
lead to terminal V.Ω
,
and the black test lea
d
to terminal COM.
