Procedure 12. BTl Battery

Warning Battery BTl contains lithium polycarbon monofluoride. Do not incinerate or puncture this battery. Dispose of discharged battery in a safe manner.

Caution

To avoid

loss of the calibration constants stored on the A2 Controller

 

assembly, connect the analyzer to the main power source and turn on before

 

removing

the battery.

 

 

 

The battery used in this instrument is designed to last several years. An output voltage of +3.0 V is maintained for most of its useful life. Once this voltage drops to +2.6 V, its life and use are limited and the output voltage will deteriorate quickly. When the instrument is turned off, stored states and traces will only be retained for a short time and may be lost. Refer to “State- and Trace-Storage Problems” in chapter 9,“Controller Section”, in this manual. The battery should be replaced if its voltage is +2.6 V or less.

Removal/Replacement

1.Locate the battery assembly cover on the analyzer’s rear panel. Use a screwdriver to remove the two flathead screws securing the cover to the analyzer.

2.Remove the old battery and replace it with the new one, ensuring proper polarity.

3.Measure the voltage across the new battery. Nominal new battery voltage is approximately t3.0 V. If this is not the case, check the battery cable and A2 Controller assembly.

4.Secure the battery assembly into the analyzer.
