WARNING
Do not remove the BITE 2/2P transmitter current source
leads from the battery until the transmitter is powered
off. Always disconnect the current source leads from the
battery before removing them from the J2 connector on
the transmitter. Do not leave the BITE 2/2P connected to
the battery when not in use.
If the LCD displays "Lo_A", refer to page 88 under
"Maintenance and Troubleshooting."
The wire for the
current source
lead
set extends from only one
side of each pair of jaws.
Section the battery system by connecting the
current source
leads
across individual sections of the string to isolate high-
resistance or open cells and straps. (See "Sectioning a
Battery System” below for the correct procedures.)
Sectioning a Battery
System
To test certain battery systems with the BITE 2/2P, you must
measure individual sections, one at a time. Examples are
included in the following subsections.
Sectioning a Battery
System Greater than
275 Volts
The nonpolarized coupling capacitor in the BITE 2/2P
current source is limited to 275 V. This restricts the current
source applied across battery systems of 275 V dc and
higher.
If the battery system to be tested is greater than 275 V, you
must test the system in sections that are 275 V or less. It is
recommended that you section the battery in equally-sized
sections.
Figure 5-2 shows a 600 V dc UPS system in which the source
current leads are connected across a 200 V section of the
battery string.
