CHAPTER 1: INTRODUCTION

Service and maintenance personnel who desire more technical information than is presented

in the PC Series User’s Guide should use this manual. Any component level troubleshooting

or board replacement should be done by factory authorized personnel only.

The PC Series has three ranges of weight capacities. The PC-30 is a 30 lb (15 kg) scale, the

PC-70 is a 70 lb (30 kg) and the PC-150 is a 150 lb (70 kg) scale.

CHAPTER 2: LEGAL FOR TRADE SEALING

2.1 OVERVIEW

The scale can be prepared for commercial use by sealing access to the calibration switch, to

meet the requirements for a legal-for-trade scale.

2.1.1 SEALING THE SCALE

Once calibration has been successfully completed, then the scale can be sealed as

follows:

1. Referring to Figure 2-1, locate the calibration switch on the back of the scale.

2. Replace the calibration switch cover by securing with the two drilled head

screws.

3. Thread a wire security seal through the openings in both drilled head screws.

This prevents access to the calibration switch. Refer to Figure 2-2 for more

detail.
