7600 SERIES - OPERATIONS

 

SECTION 1

 

INTRODUCTION

 

This manual covers the 

Operations and Programming/Calibration of the 

Pennsylvania Model 7600 Series Scale.

 

The 

7600 

has been designed to be simple and easy to operate.  It  also has many features that 

make it extremely versatile to use such as: 

• 

Standard RS-232 Interface with a selectable output for communications with a computer 
or printer.  

• 

Adjustable response time  

• 

Single board electronics for ease of servicing.   

• 

Simple one button counting operation. 

• 

Weight reading may be switched between two weighing units. 

• 

May be programmed as either weigh and count or weigh only. 

• 

Keypad entry of tare weight. 

• 

Keypad entry of piece weight. 

• 

Optional second weighing platform. 

In addition, the 

7600

 can be calibrated with the keypad or through the RS-232 Interface to match 

the requirements of the application on hand, as it employs a digital calibration technique that 
eliminates dip switches and potentiometers.   

INSTALLATION and SET-UP INSTRUCTIONS (Scale Version)

 

The 7600 Series Scale has been packaged for shipment to ensure safe, damage-free arrival.  
Please use reasonable care when removing the unit from the shipping carton, and retain the origi-
nal packaging materials in case reshipment is required. 

NOTE:TO PROTECT THE WARRANTY, FILL OUT AND RETURN THE 
WARRANTY CARD AND THE SCALE CONDITION REPORT.

 

 

To prepare the 7600 for operation, follow the procedure outlined below.

 

1.  

After opening the shipping carton, remove the molded foam top from the carton. (On 2 
lb. and 5 lb. capacity scales the platform is packaged on top of this foam, remove it first 
and lay it aside.) 

2.  

Gently lift and remove the stainless steel platform cover only. (On 2 lb. and 5 lb. capacity 
scales the platform is packaged separately and does not need to be removed.) 

3.  

Remove any options which may be packed with the scale. 

4.  

Carefully remove scale from the packaging by grasping both sides of the base. 

 

DO NOT LIFT SCALE BY THE TOP SPIDER OR SUB-PLATFORM 
ASSEMBLY

5.  

Place the scale on a stable, level surface for operation.  

6.  

Adjust the corner leveling feet until the level bubble indicates the unit is level. Firmly 
tighten hex jam nuts on the leveling feet. (Any time the scale is relocated, it should be 
leveled.)
