SETUP AND CALIBRATION PROCEDURE
This scale was calibrated at the factory and should not require adjustment. In the event that the scale
should need calibration, the following describes the Calibration of the Price Computing Scale. A
qualified technician should perform this function to maintain the instrument’s high degree of accuracy.
Before beginning calibration, the following equipment is required:
Calibration test weights (6 lb for PC-10, 15 lb for PC-20, or 30 lb for PC-30)
(3 kg for PC-10KG, 6 kg for PC-20KG, or 15 kg for PC-30KG)
No. 1 Phillips screwdriver to remove side cover
With the scale power off, remove the four (4) screws and two (2) calibration sealing tabs securing the
right side cover (as viewed from the scale front) and remove the cover. Referring to the illustration,
locate the calibration switch S1. Push and hold calibration switch S1. Press the ON key to turn power
on. The weight display window will show CAP=.
If sealing wires require breaking for purposes of calibration, proper procedures
covered under the National Institute of Standards and Technology Handbook 44
must be adhered to.
Note: The unit price window will usually contain the current value for the label in the capacity window
if setup has been previously performed. Subsequent keystrokes will replace the current value.
CAUTION!! If power is interrupted during setup and calibration, new values
entered are lost. However,
all previously entered data will be retained. Note that
new data entered is stored when the “donE” messge is displayed at the end of
setup and calibration.
1. CAP= Select desired capacity value of 3, 6, 15, or 30, and press ENTER.
2. Lb= Select 1 (Yes) if lb, 0 (No) if kg and press ENTER.
