BITE ® 3
Battery Impedance Test Equipment
ACCESSORIES
The BITE 3 has many accessories that enhance its
versatility. There are several lead sets, a printer,
lighted probe extensions and a CT.
The lead set family contains:
■ AMP/Burndy lead set for small telco batteries
■ Quick Disconnect lead set for ELU systems, security
systems, etc.
■ Kelvin Clip lead set for other types of batteries
The CT is for measuring escape current in short
strings in parallel configurations. The lighted probe
extensions are ideal for measuring batteries in (dark)
cabinets. The extensions eliminate the need to take
the battery off line and can be tested during normal
working hours, saving time and money. As with
previous BITEs, it is a one person job since the
batteries need not be removed from the cabinet.
