4215-HS Indicator
Manual
(PM-4101)
Calibration Command (C)
This command has 8 subcommands. Calibration Check (CC) is used to run a shunt calibration check on a load
cell. Calibration Begin (CB) starts the calibration of a new or existing load cell. Calibration by millivolt-per-Volt
(CV) runs a calibration using the load cell mv/volt constant. Calibration by Masses (CM) does a two or five point
mass calibration. Calibration by Shunt (CS) does calibration based on the shunt value of the load cell. Cali
-
bration Escape (CE) cancels a calibration that is underway. Calibration counts per Inch View (CIV) displays the
current setting of the encoder counts per inch constant, and Calibration counts per Inch Set (CIS) lets you set
the encoder counts per inch constant.
Calibration Check Command (CC)
The Calibration Check (CC) command runs a calibration check on the currently selected load cell. Note that
the load cell should not be under load when this check is run. During the 10 second shunt calibration the front
panel will show “RS232 Cal Check”. After the 10 seconds the unit will return to run mode and send the ac
-
knowledge line shown below. This indicates both the current reading of the shunted load cell and the reading
that was recorded when this load cell was last calibrated.
Example:
@123CCA
Acknowledge:
@123 Cal Check Ch A, S/N 123456
Shunt Value is 49.532 Lb
Cal Value was 49.531 Lb
Calibration Begin Command (CB)
The Calibration Begin (CB) command is a 4 part command used to start a calibration by any method. You must
issue a CB command before trying calibration by mv/volt, masses, or shunt (CV, CM, or CS). While the Mod
-
el 4215-HS is being calibrated using the remote commands, the front panel will show “RS232 CAL STARTED”.
Pressing the front panel Esc button will cancel the calibration and issue a warning to the RS232 terminal. If
any remote commands other than calibration commands are issued the calibration will also be canceled. The
acknowledge will indicate if this is a “New Load Cell” or if you are going to “Overwrite” existing data. If you do
not wish to overwrite use the CE command to stop this calibration. Another method of overwriting existing
data is to delete the sensor first and then calibrate.
The format for the CB commands are
CB1(space)(channel)(serial number)#
CB2(space)(month)(day)(year)
CB3(space) (excitation)(calibration unit)
CB4(space)(rated load)#
