Battery testers should not rely solely on manual
operation or automated scripts for safety. Errors can
subject batteries to overcharging, which can result in
battery damage or fire.
Batteries should be monitored by independent hardware
for one or more of these unsafe conditions:
• Over voltage
• Over temperature
• Excess pressure
• Excess gassing (H2)
The HV Interlock on the 900 EX is provided to allow a
hardware monitor to shut down the 900 EX in the event
of an unsafe battery condition.
In Current, Power, or Resistance Mode, do not open
or close the circuit under load. If the external load
contact opens, put the 900 EX into Standby Mode
before closing the external contact. This can be achieved
manually or via instructions in a script. Failure to put the
900 EX in Standby Mode after the external contact is
opened may cause serious damage to the equipment.
Use the High Voltage Interlock Connector to put the unit
into Standby Mode. When the high voltage interlock
connection is opened, the unit goes into Standby Mode.
Consult the Customer Service Department if assistance
is required.
Channel A and Channel B can be used as a source or
sink. When Channel A is used as a source and B as a
sink or vice versa, the positive and negative terminals of
Channel A are connected to the corresponding terminals
of Channel B.
