Installing or Replacing the Battery
Replace the battery when the
red LED
lights, or when both
red and
green
LEDs are off when the probe is turned on.
Warning
To avoid electrical shock, disconnect the differential
voltage probe from any conductor, and disconnect
the ScopeMeter
®
test tool or oscilloscope before
replacing the battery.
Follow the procedure (steps 1 to 5) to install or replace the battery.
Characteristics
FLUKE guarantees the properties expressed in numerical values
with the stated tolerance. Specified non-tolerance numerical values
indicate those that could be nominally expected from the mean of a
range of identical differential voltage probes.
Input Characteristics
Input Probe Tip Style:
Shrouded banana probe tip
Probe Cable Length:
1.5 meter (60 inch)
Maximum Input Voltage to Ground:
600V CAT III
1000V CAT II
Installation Category III refers to distribution level and fixed
installation circuits inside a building. Installation Category II refers
to local level, which is applicable for appliances, and portable
equipment.
Maximum Differential Input Voltage:
1000 VDC, or
1000 Vrms, or
1200V (DC+AC peak)
Note
(DC+AC peak) limit is determined by the point at which
the differential voltage probe starts clipping.
For derating of each input probe (red or black), see figure below.
