Incorrect Battery Charge Shown after Inserting a new Battery

The information provided is for help with Commtest Instruments products:

• vb instrument

SYMPTOMS

When a new battery pack is inserted into the instrument the percentage charge and voltage values no longer match.

CAUSE

The vb instrument does not use intelligent batteries and so cannot identify the percentage of capacity of the new battery. However the actual voltage value displayed in the instrument will be accurate. The % value will be in error.

SOLUTION

To get the voltage value and the percentage value to realign you need to perform a battery recondition as outlined below.

Reconditioning a Battery

• From the Main Menu press [7] Battery Management.
• Press [1] Charger Control then press [2] to recondition the battery. Discharging is indicated by the flashing 'DISCHARGING' message on the screen.

Inserting a Fully Charged Battery into the Instrument

• From the Main Menu press [7] Battery Management.
• Press [1] Charger Control then press [3] Fresh Battery Inserted. This will ensure that the battery percentage is set to 100%.
