IntroductionIntroduction

Thank you for purchasing a PS shipping scale from METTLER TOLEDO. The legal-for-trade model of the PS60 shipping scale is a low-profile, 150 ×

0.05 lb (60 × 0.02 kg) capacity scale designed to meet the needs of the legalfor- trade parcel/manifest markets. The PS60 also features an auto-ranging and/or weight classifying version with a capacity of 0 - 60 lb × .02 lb / 60 150 lb × .05 lb. Both are NTEP approved. (See Chapter 3 for a complete list of builds.)

The legal-for-trade model of the PS6L shipping scale is similar to the PS60 but has a higher resolution for letter weighing. It has a weight classifying, auto-ranging capacity of 0-7 lb x 0.1oz / 7-70 lb x 0.2 oz / 70–149 lb x 0.5 oz.

The PS2+ model is a large roller top scale with a capacity of 250 x 0.1 lb (100kg x 0.05kg). It is designed for parcel weighing in conveyor systems.

The following are standard features built into each PS shipping scale.

• 150 lb or 250 lb capacity “Eagle+” load cell

• Die-cast aluminum base and sub-platter

• Stainless steel or plastic platter

• RS-232 serial interface to the scale base

• Automatic power down mode for energy conservation

• 12 VDC, 60mA power supply unit (wall-mount transformer)

• 2-key weight indicator

The PS operates within an input voltage range of 7.5 to 15 VDC (at 60 mA).

• An external, wall mount 12 VDC voltage converter supplies power to the

PS.

• An optional D-cell battery kit can be used to power the scale continuously

for at least 40 hours. Battery life is extended with the on/off switch in the “off” position.

• An optional 12 VDC Car Lighter Jack Cable can power the PS.

The PS60 operating range is −10° to +40°C (+14°F to +104°F) at 10 to 90% relative humidity, non-condensing. The PS6L & PS2+ operation range is +10° to +40°C at 10 to 90% relative humidity, non-condensing. The shipping and storage temperature range is −20° to +60°C (-4°F to +140°F) at 0 to 95% relative humidity, non-condensing.

This chapter gives detailed instructions and important information you will need to install the PS successfully. Please read this chapter thoroughly before you begin installation. This information is also covered in the PS Operator Instructions.

Please inspect the package as the carrier delivers it.

If the shipping container is damaged, check for internal damage and file a

•

freight claim with the carrier if necessary. If the container is undamaged, open the box, remove the scale, and place it

•

on a solid, flat surface.

Please keep the packing material and shipping insert in case the scale needs to be returned to METTLER TOLEDO. The PS is a precision instrument and may be permanently damaged if not shipped in factory-approved packaging.
