Chapter 2. The Validator Hardware
2.2.6 Backup Battery
The Validator is equipped with a lithium ion backup battery to provide short-term power in
case of AC power loss. The intent of the battery is to provide sufficient time (approximately
60 minutes) so that you can perform an orderly shutdown of the system. When the Validator
detects that the AC power has failed and the system is running from battery, it displays an
icon on the front panel.
IMPORTANT: In the event of power glitches or short-term drops in supply voltage
(“brownouts”), there is a remote chance that the Validator will fail to fall
back to its backup battery. In this case the Validator will reset and potentially
lose any study data stored in internal memory. To prevent this from
occurring, it is recommended that you connect the Validator to an
Uninterruptible Power Supply (UPS) in areas likely to experience brownouts.
CAUTION! Power is still supplied to the unit via the backup battery after the AC
power cord is unplugged. Remove battery from the battery pack
before servicing the instrument.
The Validator monitors its own battery voltage. When the battery has approximately six
minutes of power remaining, the Validator stops collecting data and closes its data files. To
ensure long service life and minimize the “memory” effect inherent in lithium ion batteries, it
is a good practice to completely discharge and recharge the lithium ion battery on a periodic
basis.
The unit is equipped with rechargeable battery pack (
