METTLER TOLEDO PS Shipping Scale: Technical Manual

Calibration Program

Block

This program block lets you calibrate the scale with the appropriate test weights selected

above. (Metrology PCB jumper must be removed per the first page of this chapter.)

To calibrate the scale:

1. If Cal is not displayed, press the UNITS key to display the Cal prompt, then press

ZERO to display YES or NO. Select “Yes” to calibrate or select “No” to abort or

bypass calibration.

o If “No” is displayed, press the UNITS key to accept. The PS continues to the

End program block. Skip the rest of the Calibration steps below.

o If “Yes” is displayed, press UNITS to begin the calibration process. Go to step 2

below. Any changes to the above set up parameters will be saved at this time.

After the completing the calibration sequence below, the scale will

automatically save the calibration data, exit setup mode, and reboot the scale.

The End program block will not be displayed after calibrating the scale.

2. At the Empty prompt, insure that the platter is on the sub-platter, there is no weight

or debris on the platter, and there is nothing touching the platter. Once the above

items are confirmed, then press UNITS key.

3. At the Add XX prompt the unit is indicating how much weight should be placed on

the platter as selected in the Calibration Weight function above. A cursor appears

over either lb or kg on the lens to indicate which units are required. Place the

appropriate weight on the platter, then press UNITS. The scale automatically

determines a span factor then indicates Done while the calibration values are

saved.

4. Remove the calibration weight from the scale platter and press the UNITS key again.

The scale will power down and all parameter selections made in previous program

blocks will be saved. Scale will automatically restart . It will no longer be in Set Up

mode.

5. When the scale powers back up, check the accuracy of the scale. Verify zero and

span using the test weights. Place the test weight at multiple locations on the

platter.

The PS scale is now calibrated. If desired, re-install Calibration jumper if no more

programming is to be done. See section below on how to seal the scale for Legal for

Trade applications.

Note: If the calibration sequence is

the end of the programming

process, re-install Cal jumper

when completed.

o Disconnect power to the scale

o Remove platter and PCB cover

o Re-install calibration switch

(W1 jumper)

o Install cover and platter

o Power up scale.

Note: If you have not gone through

the previous steps in this chapter,

Cal is only displayed when the W1

Jumper is removed from the PCB

and the scale is in the set up

mode.

o See first page of this chapter

to remove W1

o To access the set up mode,

press the UNITS key for 8-10

secs.
