* Note: Optional programming On-Off switch may installed
in line with terminal C. Locating this switch near the DCE
will simplify the programming of certain functions such as
the battery bank capacity, charge efficiency and Peukert’s
Exponent. While the factory set (default) values of the latter
two functions will work in most situations, the default value
for battery bank capacity (factory set at 500A-H) will vary
from installation to installation.
Carefully check all your wiring against that shown in
FIGURES 2 and 3. If everything is wired correctly you can
mount the DCE in the instrument hole. Be sure the bulkhead
gasket is in place and use only finger tension to tighten the
bracket hold-down nuts.
Do not overtighten the bracket or
you may damage the case
-
do not use tools to tighten the
nuts.
Note: Because wire lengths and sizes will vary with each
installation, the auto zero procedure that follows should be
performed to initialize the unit.
Auto Zero Procedure
To make the ammeter read zero when no current is flowing,
press and hold the
key for 10 seconds while viewing
Amps. The DCE will display "AUTO", automatically zero
the reading and save the auto-zero information into memory.
If the reading does not stop at zero, repeat the above proce-
dure until it does.
Calibrating/Zeroing the Instrument
The DCE is factory calibrated and under most circum-
stances should not require re-calibration after being
installed. If however, you suspect, then confirm incorrect

voltage and/or amperage readings, the unit may be re-
calibrated as follows:
To re-calibrate the voltmeter, press and hold the
key
while applying power to the instrument. Use the
and
keys to make the displayed value read correctly. Press
the
key for 1/2 second to save the calibration data to
memory.
To re-calibrate the Ammeter, press and hold the
key
while applying power to the instrument. Use the
and
keys to make the displayed value read correctly. Press
the
key for 1/2 second to save the calibration data to
memory.
Key Functions
The
keys are used to select what to
display, backlights, calibrate volts/amps, turn alarms on/off,
set alarms and set/change constants. New information is
automatically saved to memory.
Turning Alarms ON/OFF
Press the
key 1/2 second to turn alarms ON. In Voltage
mode, the Battery 1 icon will blink. Press the
key 1/2
second to turn the alarms OFF.
Backlight Intensity
Press
the key 1/2 second to adjust the backlight level for
night-time viewing. Each time you press the
key 1/2
second, the level will get brighter 1, 2, 3, 4, OFF, 1, 2...etc.
Screw terminal pin (D) must be connected to battery hot (+)
for the backlights to work.
