3.2 Quick Test Mode - Charger Circuit Test
Similar to the other Quick Test modes the Charger Circuit test is a tool to help evaluate the performance of the charger
circuit under an open and loaded condition. Both the open voltage OCV and LCV values are displayed. The load applied
is based on the Ah value entered and is calculated to place a light load that should be will within the nominal range of the
charger circuit. Although the 603B does not test 24 volt batteries it can test most 24 volt charger circuits.
An adapter is provided with an F1 tab on one end and F2 tab on the other. Using the correctly sized tab, plug one end of
the adapter into the leads of the system charger circuit. The other end of the adapter is used for an attachment point for
the 603B tab type, alligator clips.

1. Connect the 603B cables and verify the positive and negative leads are correct and the Reverse Polarity LED is not
illuminated.

2. Press the button to move to the Quick Test menu.
The cursor (underline) will be located in the Ah: field.
4. Use buttons to increase or decrease the Ah: value until it matches the battery under test Ah.

5. Press the button to begin the test. The back light will turn off indicating the test has started. After approximately
2 seconds the back light will illuminate and the results will be displayed.

Both “OCV:” and “LCV:” will be measured and displayed. If the LCV voltage is significantly below the OCV: the voltage
charger circuit could have a problem. Contact the control panel (charger), manufacturer for more information.
The back light will turn off indicating the test has started.
Both the open voltage OCV: and the loaded voltage LCV: are displayed. If the LCV drops will below the OCV value the
charger circuit regulator could be faulty. The results of the test must be interpreted by the technician as each type of
charger circuit is different. Contact the charger circuit manufacture for more information.
Tip:
In a two battery system use the Ah value of one battery. Example, a fire alarm control panel has two 12 V
batteries connected in series to provide the FACP with 24 volts. The charger circuit in the FACP is designed to charge
at just over 24 volts. The 603B will use this Ah value of one of the batteries to calculate and apply a parcel load on the
charger circuit.
