Open Lead Detection
The 7
00
Series
Handheld
Bond
M
eters
feature open
lead detection for all ranges. This
feature monitors the test current across the leads
on each channel
.
A small current is
sourced between the Kelvin connection of each channel’s test leads.
Th
is
detection is
independent of whether a DUT
is
or is
not connected.
If the unit detects
a
n
open
circuit in either channel it will illuminate the OPEN annunciator
along with the channel(s) the unit has detected an
open
circuit in.
When using the unit
with MKP, BKP, and MCP probes, the OPEN
and channel
annunciators will be illuminated when not connected to a DUT.
Battery Indicator
The battery voltage indicator provides a visual representation of approximate remaining
battery life. It is located at the top
-
right of the
display.
The battery voltage indicator uses three bars
to represent remaining battery life
.
Figure 4
shows the approximate battery life for each
bar.
At zero (0) bars, the instrument will
momentarily display
Lo
bATT
and initiate a
shutdown sequence. To prevent disruption of
the measurement process, the batteries
should be replaced before the battery voltage
indicator reaches zero (0) bars.
