Calibration
86 W-4510 Weigh Scale Technical Reference Manual
Step 4: Collecting data for the zero and span
This step sets the upper and lower detector signal limits that are associated with the
endpoints of the calibration. These endpoints display graphically as Cal_lo and Cal_hi. You
do not have to collect data at the endpoints of the calibration, but in general the closer to the
ends the better.
Perform this procedure one time only for the initial calibration. Calibrations that follow the
initial cal use the self-contained absorber.
Calibrate zero—low on process channel #1
210 CALIBRATE LOW
ON PROCESS
YES NO (ABORT)

Before starting this procedure:
5
Have the process at zero
5
Have the actual process value for the empty belt
