Cycling through these screens is achieved by operating the
Mode/Ack switch on the
front panel. The display will automatically return to Screen 1 in 5 minutes if left on
Screen 2 to 5.

BOOST CHARGING BATTERIES
5.3.1
Manual operation
The boost charging circuit is achieved by pressing the
Boost button on the front
panel. The system will then remain in boost mode until the internal boost timer
completes the preset boost cycle.
The boost mode can be terminated by pressing the
Boost button again.
5.3.2
Automatic boost
Charging of the system commences if the battery charging current exceeds a
selected value for a preset period. Both the battery current value and the preset
period are user adjustable. (See User Programmable Set Point Instructions).
Automatic boost mode is terminated by pressing the
Boost button.

BATTERY TEST
5.4.1
MODE 1: Battery Impedance Test
The Battery Impedance test calculates internal resistance within the battery by
drawing a high current pulse (approx. 50A, which does not indicate on front display)
and by monitoring the
battery’s voltage drop.
5.4.1.1
PROCEDURE:
1)
Momentar
ily press ‘BATT TEST’ button
2)
Display goes automatically to capacity and Last ratio menu. Wait for 5-6
seconds for Impedance and Baseline mOhms to appear on the screen.
3)
Repeat step 1 until Impedance mOhms shows a stable reading after multiple
trails (proximately 5 times).
5.4.1.2
First time or New Batteries:
After observing that the Battery Impedance is stable, hold Reset button for 6 seconds
to set the measured impedance as the baseline impedance. This is done to obtain a
reference impedance to compare with future impedance values. This baseline
impedance is now the reference for future impedance measurement and comparison.
