For the pre-load static test, the Analyzer automatically determines the voltage of the battery. The Amphour rating is entered to set the parameters prior to the load testing. A voltmeter function may be used to check the charging circuit.
For the dynamic load test, a microprocessor controlled load test sequence is operator initiated with the battery disconnected from the charging circuit. The load current is based on the entered AmpHour capacity. The battery condition is evaluated during the load test and is displayed on LED’s as: Good, marginal, bad
The 4110 will perform an additional test that determines the remaining capacity of the battery. This result can be compared to the minimum standby requirement to determine if the battery will meet the demands of an extended power failure. A math calculation routine is available in the 4110 to size batteries for various fire, UPS, and security systems.
