Calibrating Your Module

In this chapter we tell you what tools you need and how to calibrate your

module.

In order to calibrate your input module you will need the following tools

and equipment:

8300A or equivalent

Alignment tool

P/n 35F616, for pot adjustment: Newark Electronics,

500 N.Pulaski Rd., Chicago, IL

The analog input module is shipped from the factory already calibrated.

If necessary to recalibrate the module, you must calibrate the module in an

I/O chassis. The module must communicate with the processor and

industrial terminal. Calibration consists of adjusting the 10V reference and

nulling the input offset.

Important: The module must be powered up for at least 30 minutes before

attempting to calibrate.

ATTENTION: Do not attempt to calibrate your module until

you have read and thoroughly understand this procedure. Also,

do not attempt to calibrate this module in an operating system.

Damage to the equipment or personal injury may result.
