The DLCA allows either precision calibration or weightless
calibration. The Precision Calibration method is described
below. Weightless Calibration begins on page 4-8.
Calibration can only be performed when the password has not
locked the DLCA. To unlock the DLCA, see the Password
parameter P.00 on page 5-4.
Precision calibration
Use this method when applying a known weight with a rope in
the web path to the load cells for calibration. Typically this
should be 10% of the load cell rating or greater.
Enter the programming mode by pressing and holding [+] and
[-] for two seconds.
Use the [+] and/or [-] buttons to go to parameter P.01. Press
[] to see the present load cell excitaion voltage. Select either
5V or 7.5V. When using MAGPOWR load cells select 7.5V. Press
and hold [] for two seconds (until the display starts flashing)
to store the changes.
Use the [+] and/or [-] buttons to go to "CAL1". Press [] to
enter the CAL1 sub-menu.
Display now shows C1.1. Unload the load cell roller and press
[]. The DLCA will now zero out the idler roll weight and show
a wait display. After zeroing the DLCA will automatically
increment to the next parameter.
