AT851 Battery Aging Tester
5.
Advanced Testing Function
This section includes the following 3 advanced testing functions
：
Short Circuit On/Off (SHT)
Battery Testing Function (BAT)
Battery Life Testing Function (BLT)
5.1
Short Circuit On/Off (SHT)
AT851 can simulate a short circuit at its input by turning the load on with full-scale
current (3.2A@Low Range and 32A @ High Range).
The actual value of the electronic short is dependent on the mode and range that are
active when the short is turned on. In CV mode, it is equivalent to programming zero
volts. In CC/CP/CR mode, it is equivalent to programming full-scale current for the
present CC range.
Turn Short On/Off
：
Step 1:
In normal operation mode (CV/CC/CP/CR) and the load input is turned off,
choose an operation mode (CV, CC, CP or CR).
Step 2:
press
shift
+
Short
to enter Short Circuit Testing Function.

.
Step 4:
You can press

key to watch Current (I), Power(P) or Resistance (R)
measurement value.
Step 5:
Turn off load input by pressing
ON/OFF
key.
Step 6:
Press

to return normal operation mode.
5.2
Battery Testing Function (BAT)
Capability Test
Electronic load uses CC mode to do the capability test. Battery testing cannot work in
CV, CR or CP mode.
The discharge curve can be displayed in PC analysis software if you connect AT851 to
PC.
5.2.1
Set up battery testing parameter
Step 1:
In normal operation mode (CC), turn off the load input and connect with a
tested battery.
Step 2:
Press
