Introduction

1.1 General
Thank you for purchasing the PS7 paint scale or the intrinsically safe PS7-X version. The PS7/PS7-X makes it
possible to mix components in predefined proportions by weighing. The scale has a number of correction modes to
compensate for errors made while weighing the components. A built-in RS232 interface allows the scale to be
connected to a printer, a computer, or an auxiliary display.
Please read through this manual carefully and always follow the instructions!

Safety and environment

– Do not use the PS7 scale in hazardous environments where there are explosive mixtures of gases, vapors, or
dusts.
In hazardous areas, a type PS7-X scale must be used. The certified METTLER TOLEDO power supply unit must
always be used for connecting the scale. The operating instructions for the power supply unit must always be
observed and followed. Because of the danger of electrostatic charge, it is only permitted to use a protective cover
in hazardous areas if the cover is made from statically non-hazardous material.
– To connect the scale to the power supply, use only the AC adapter (PS7) or power supply unit (PS7-X) supplied
with the scale. Make sure the voltage printed on the adapter or supply unit is the same as the local power supply
voltage. Check the cable of the AC adapter/power supply unit regularly. If the cable or the AC adapter/power supply
unit is damaged, the scale must not be used.
– Use only recommended accessories and peripherals.
– Treat the scale carefully, it is a precision instrument. Knocks to the weighing pan, or overloading it excessively,
damage the scale.
– Before starting to clean the scale, disconnect it from the power supply!
Cleaning: Use a moist cloth (no acids, alkalis, or solvents). If the scale is heavily soiled, remove weighing pan
protective cover (if present) and the leveling feet (certified scales only), and clean these parts separately. Observe
company- and industry-specific regulations regarding cleaning intervals and permitted cleaning agents.
– When disposing of the scale, observe the applicable environmental regulations.
1.3 Notes regarding certified models
On certified models the following functions are deactivated:
– Formula weighing (factor weighing and formula weighing with correction)
– Changing the weighing unit (on certified scales the weighing unit is set to "g" as standard)
– Calibration (certified models must be adjusted/calibrated by an authorized METTLER TOLEDO service representative)
