Operation highlights
At the core of the 603B is a programmable DC electronic load. This load can
be programmed in the field to test control panel outputs or end of line output
circuits. Load current can be set from 0.5 to 10 Amps and the time can be set
from 0.5 to 5.0 seconds. Open and loaded voltage is displayed after the test is
completed.

Load test mode
The 603B can be calibrated by the user through the USB port using a
computer and reference power supply. Firmware updates are also installed via
the USB port.

State of Charge (SOC) weighting
When the battery’s internal resistance (IR) is above the user-set nominal value,
the open voltage measurement no longer results in an accurate SOC value. The
603B uses weighted values to more accurately represent the SOC. This feature
can be enabled by the user and its state is recorded in Record mode.
SOC profile tables are used to evaluate the battery’s state of charge. One
default and 3 user-configurable tables are available for characterizing 6 V and
12 V batteries. The user defined tables allow advanced users to tune the 603B
to meet their specific needs.

State of Charge (SOC) profiles
Both the open voltage (VO) and the voltage under load (VL) are displayed
to provide additional information about the charger regulator circuit. Using
Record mode enables storage of results to internal memory. An adapter is
included to make it easy to connect to standard tab-type charger circuits.

Charge circuit testing
Keeping records of the battery’s operating environment such as temperature is
helpful for understanding the battery’s life. The 603B records the predefined
temperature and prompts the user for adjustment after the test is completed.
