Operation
A brief message is displayed (such as
"HELLO"). The scale enters GROSS
weighing mode. Pressing
[ON]
a second
time during normal system operation starts
the self-test.
A warm-up period of ten to fi fteen minutes
provides the most accurate readings. If the
scale is holding a load for a long period of
time (ex: overnight), the weight displayed
may vary because of zero shift created
by changes in temperature. This does not
affect the accuracy of the scale.
For example, if the system was load-
ed with 1000 Lbs, it might read 1200
Lbs the following day. The change in
temperature "zero shifted" the ZERO/BAL-
ANCE from 0 Lbs to 200 Lbs. When unload-
ing the scale, the display will count from
1200 to 200 Lbs for a total of 1000 Lbs.
• TO ZERO / BALANCE THE SCALE
1. Press
the
[
NET/GROSS
] key and within
three seconds,
2. Press the [
ZERO
] key.
• TURN ON THE SCALE:
1. Press
[
ON
].
• TURNING OFF THE SCALE:
1. Press
[
OFF
].
The
ZERO/BALANCE
will "balance off"
trailer, bin, or platform weight.
The
"ZERO"
message is displayed and the
scale is placed in the GROSS mode.
Pressing only the
[ZERO]
key will cause
the message
"TO ZERO / BALANCE
PRESS NET/GROSS -- THEN ZERO"
to
be displayed.
If the supply power is below the "low bat-
tery threshold" (10.5 Volts), the message
"
INDICATOR CANNOT BE ZERO/BAL-
ANCED -- LOW BATTERY VOLTAGE"
is
displayed. The message
"LO BAT"
will be
periodically shown on the display (approx.
every fi ve seconds) to alert the operator of
the low battery condition.
Loss of power does not affect the
ZERO/
BALANCE
or "Setup/Calibration" values.
