DA ALOG OUTPUT CAL. FOR 2350A

APPENDIX D, ANALOG OUTPUT CAL. FOR 2350A

The initial analog output adjustment will be set

at the factory before shipment at standard

values (4-20 mA or 1-5 V). It may be necessary

to check and/or adjust these values, depending

on output cabling or impedance. The

adjustment may require two persons if the

units are some distance apart. It will require a

good digital meter to check the zero and full

scale values at the receiving end. The scale or

span value can be adjusted by a PC with

MON2000 software when the values are known

at the receiving end.

It is possible to calibrate the analog outputs

using different engineering units. Two

examples are described below using both volts

and percentages.

D.1

CALIBRATING BY VOLTS

This example assumes that an analog output

channel needs to calibrated to a span of 1-5 V.

To calibrate an analog output by adjusting the

voltage,

1. Use the Application > Analog Outputs menu

to access this function.

2. The Analog Outputs dialog appears.

The 4-20 mA outputs are

calibrated similarly except

the current is measured

instead of the voltage.
