METTLER TOLEDO PS15 Shipping Scale Technical/Operators Manual
(09/03) 2-8
The sequence for selecting your GEOCAL™ code is as follows:
1. Press the ZERO key to display the first code option and continue pressing
it to scroll through all of the available codes.
2. Press the UNITS key to select the code for your location. The display will
then prompt done. Press the UNITS key again to restart the scale.
Power-up Sequence
The PS15 goes through a power-up sequence each time power is applied or
the scale is brought from its power-down ("sleep") state. The scale performs a
diagnostic test on its ROM and RAM, then proceeds to normal operating
mode. The power-up sequence is as follows:
1. All segments of the display characters are activated. This verifies
operation of all segments.
2. The scale displays the software part number followed by the software
revision status.
3. The scale then captures zero (if the zero reading is within ± 10%
calibrated capacity on power-up) and is ready for normal operation.
Full Calibration
WARNING
ONLY PERMIT QUALIFIED PERSONNEL TO
SERVICE THIS EQUIPMENT. EXERCISE CARE
WHEN MAKING CHECKS, TESTS AND
ADJUSTMENTS THAT MUST BE MADE WITH
POWER ON. FAILING TO OBSERVE THESE
PRECAUTIONS CAN RESULT IN BODILY HARM.
You can calibrate the PS15 scale using the UNITS and ZERO keys, or you can
calibrate the unit remotely from a computer terminal through its Host
interface. Details on calibration using a Host Interface are given in the
Appendix at the end of this manual.
To calibrate the PS15 at the scale:
1. Disconnect the power from the scale.
2. Remove the platter, break the legal-for-trade seal (if present), and remove
the PCB cover plate to give access to the PCB.
3. Remove the calibration jumper (W1 in Figure 2-g).
To “awaken” the PS whenever it is in
sleep mode, press the ZERO key.
