VOLT / AMP digital meter switch
This switch is used to select the measurement display mode of the digital
meter. The output voltage or the output current modes can be selected.
VOUT+, VOUT test points
These test points are used to measure the voltage at the point of regulation.
A 5 kohm resistor is placed in series with both sensing leads to prevent
short-circuits at the jack terminals. The resistor may affect reading
accuracy, depending on the impedance of the meter. Refer to the
Instruction Manual for your meter to determine its internal impedance and
correction factor.

4.2.6. Float and equalize voltage control

Local FLOAT / EQL switch and potentiometers
The rectifier is equipped with a FLOAT / EQL switch.
When the FLOAT / EQL switch is held in the EQL position, the rectifier
goes into equalize mode and boosts the output voltage to the value set by
the EQL potentiometer.
When the switch FLOAT / EQL is held in the FLT position, the rectifier
delivers a float voltage set by the FLT potentiometer.
Remote equalize control EQL
The rectifier is equipped with remote equalize control. This control is
activated by a remote ground signal ( BAT RTN ). The rectifier returns to
normal ( float voltage ) operation when this signal is removed.

4.2.7. Current limit adjustment and rectifier regulating test

CL ADJ potentiometer
The rectifier limits the output current to a select value ranging from 100 A
to 210 A, set by the CL ADJ potentiometer. The factory adjustment is
205 A ±5 A. Extended periods of operation in the current limiting mode
and repeated transitions between constant-voltage operation and constant-
current operation have no detrimental effect on the performance or service
life of the rectifier.
