TO CALIBRATE
Use this Calibration procedure for calibration of the CellScale using the 3750CS. If capacity or resolution
changes are necessary (such as an initial setup of a system) first reset the Calibration with the procedure on page
111. The CellScale supports up to 10 points of span calibration, however, calibrating with the 3750CS limits the
calibration to 5 span points. Zero and at least 1 span point are required for a successful calibration. The highest
value test weight should be at least 20% of capacity, but 50% or more is preferable.
Before starting the following procedure, you must be in the Top Menu Level of Calibration. See “Enable Calibration”.
1) Use the UP or DOWN scroll key to scroll to the
“STD CAL” message.
2) Press ENTER.
If this is a recalibration, jump to step 11. If this is the initial calibration or
following a Reset Cal procedure, go to step 3.
3) Use the UP or DOWN key to tell the scale what
power source the 3750CS will use: “PWR AC” for
115 or 230 VAC, or “PWR VEHI” for either vehicle
power adapter or for running the system from a
12V SLA Battery.
4) Push ENTER when the proper choice is displayed.
In this example the 3750CS is an AC unit.
5) Next set the default units the scale is calibrated in.
Use the UP or DOWN key to scroll to the desired
Calibration Unit.
In this example, we’ll pick “KILOGRAM”. The capacity initially programmed
in the calibration units determines the overload value.
6) Press ENTER to set the Calibration Units.
7) Next set the capacity of the system in Calibration
Units. The display reads “CAPACITY”. Use the
numeric keys to set the capacity value.
In this example we’ll set the meter Capacity at 1000 kg. Capacities range
up to 999,999 calibration units in any units. During capacity entry, you can
back step delete any incorrect entry using the CLR (ZERO) key.
8) Push ENTER to complete the capacity value entry.
9) Next, use the UP or DOWN keys to enter the resolu-
tion in scale divisions (d). The CellScale defaults to
3000 counts or less resolution. The message display
reads “COUNT BY”. The numeric display indicates
the calculated “d” value. Use the UP key to decrease
resolution (increase the count-by). Use the DOWN
key to increase resolution (decrease the count-by).
Increments are in a 1-2-5 sequence.
In this example we’ll change the scale divisions to 0.1 kg
10) Push ENTER when the desired scale division is
displayed.
