CALIBRATION
___________________________________________________________________
6-12
For a four channel System 1100 unit, rotate the GAIN ADJUST
for CHANNEL 1 until the number appearing on the channel 1
tonnage display reads within ±1% of one-fourth (1/4) of the
sum of the tonnages exerted by the jack(s). Repeat this
procedure for channels 2, 3, and 4.
12) Release the pressure of the jack(s) and remove the jack(s) and
associated stack materials from the machine.
13) Press the EXIT key to end STATIC-CAL mode. Select the CAL-
CHECK option in the Config menu to display calibration
numbers. Press the YES key when prompted with "ESTOP WILL
ACTIVE! BEGIN CAL-CHECK (Y/N)?". The calibration number of
each channel will then appear in each tonnage display. These
are the calibration numbers for the System 1100 as installed
on the machine. It is IMPORTANT to retain these numbers so
that periodic checks for calibration can be made. It is
suggested that a copy of these numbers be kept inside the
System 1100 cabinet and that a second copy be kept in files.
If the calibration numbers displayed on the tonnage displays
vary, take the median value of the numbers displayed as the
calibration number.
14) Press the EXIT key to end CAL-CHECK mode.
Calibration is complete.
