1 Introduction

Thank you for purchasing a PS shipping scale from METTLER TOLEDO.

The PS scale, like all METTLER TOLEDO products, is designed for maximum durability
and reliability in even the most demanding shipping applications. The PS is
manufactured in one of METTLER TOLEDO’s ten ISO 9000 certified facilities so you are
assured to receive a high-quality product.

The PS scale is designed for robust use in parcel shipping, mail, and other light
industrial environments. PS scale models have a wide temperature and humidity range
and can be used on most unheated shipping docks.

The PS scale is a low profile, high precision scale designed to meet the needs of the
legal-for- trade parcel/manifest markets. The PS scale is capable of communicating
through Mettler Toledo standard and SICS protocol or in the protocols of the major
shipping carriers. The scale program can be customized or quickly programmed in a
one step process through default communication settings of the major shipping carriers.
For preconfigured models, set up is simple and easy with plug and play capability.

Power Requirements

Environmental

Chapter 1: Introduction

The PS operates over an input voltage range of 7.5 to 14 VDC, at a current of 100 mA
or less.

 For USB operation, the scale is powered through the USB port. With the low power

consumption, the PS scale is within the USB power requirements for connection to
your PC. Please connect scale directly to PC. Do not connect to a USB hub

 An external 9 VDC power supply is required for power to the PS scale for

standalone applications or RS232 applications. The scale must be powered by the
universal power supply located in the scale’s shipping box. The wall mounted
transformer is rated between 110-220V and 50-60 Hz. The power supply may
have multiple plug adapters that can be clipped to the transformer based on
available outlets.

 The power supply is not required for USB. If the power supply is connected during

USB operation, the scale will automatically sense the external power supply and
utilize it for the scale power.

Note: If the GEOCAL™ capabilities

of your PS unit have been
activated, the scale will only
prompt for the “Geo in” code on
the first power up

Note: If you missed entering the
GeoCal code on the first power up,
see Chapter 4 to reset the feature
for the next power up.

The patented GEOCAL™ feature provides the best scale accuracy. The GeoCal
feature precisely compensates for gravitational differences between the factory
location (where the scale was calibrated) and the scale’s point of use location.
Since the Earth’s gravity varies based on latitude and altitude, the GeoCal feature
allows the PS scale to maintain the sensitive factory calibration to ensure the most
accurate weighting results.

o If 0.00 is displayed than the GeoCal is not activated. No code is required. Go

to step 8. For the best accuracy, scale should be calibrated on site by a trained
technician with certified weights.

o If “GEo in” is displayed, than enter the two digit GeoCal Location Code for the

area that the scale will be used. See the chart below for the correct code.
