Resistancr Ranges
The
maximum sfe
input voltage is
!1200
volts
(dc
+
peak
ac) between
the
+
and COM
inputs or between
the
+
input and
chasis.
The
maximum
COM
floating
voltage is
!500
volts
(dc
+
peak
ac)
to
chassr.s.
The DM44
may
be
damaged
if it is operating
in the
resistance mode
(OHMS
function
selected)
and
a
volt-
age
exceeding 120
volts rms is applied between
the
+
and COM
leads.
lf the
readout exceeds
1200
volts
or
the
readout
blinks
(indicating
overrange),
immediately disconnect
the
+
lead
to
prevent possible
instrument damage.
1.
Press
both
the
VOLTS FUNCTION
push
button and
the
1.2
kV RANGE
push
button
(see
Figure
g).
2. Connect
the COM
lead
to the
reference
point
(usually
a
ground
or
test
point)
and the
HIGH
lead to the
unknown
voltage to be measured.
