CONFIGURATION MENU SCREENS:

Configuration Mode
Unlocking

Enter correct code number to access Configuration Mode.

Factory Default value is 10.

Configuration
Options

Select the required Configuration Sub-Menu Option from: Inputs; Control;
Outputs; Alarm; Communications; Recorder; Clock; Display; Lock Code or
Reset To Defaults.

INPUT CONFIGURATION SUB-MENU SCREENS

Input 1 Setup

- Sub-menu to setup Input 1. Press

to return to Input Menu

Input Type

Select from various Thermocouple, RTD and Linear mA, mV or VDC

inputs. -

see specifications section on page 245, for available input types.

Note:

Recheck the units and decimal point settings if you

change the input type.

Engineering Units

Select display units from: °C; °F; °K; bar; %; %RH; pH; psi or none.

Temperature sensor inputs are limited to °C; °F

Decimal Point
Position

Sets the maximum display resolution to 0; 1; 2 or 3 decimal places.
Numbers >99.999 never display more than 2 dec places, >999.99 never
display more than 1 dec place and >99999 always display without a
decimal place.

Temperature inputs are limited to 0 or 1 decimal place

Scaled Input Lower
Limit

For temperature inputs, upper & lower limits set the usable span. The
minimum span = 100 units, maximum span = range limits for the sensor
type selected -

see specs on page 245

For DC linear inputs, the limits define the values shown (-9999 to 9999.9)
when input is at minimum and maximum values. Min span = 100 units.

Scaled Input Upper
Limit

Multi-Point Scaling
Enable

Enables or disables multi-point scaling. This allows up to 15 point input
linearization for DC signals -

not possible with temperature sensor inputs

Scaling Point

If multi-point scaling is enabled, up to 15 breakpoints* can scale input vs.
displayed values between the scaled input limits. Each breakpoint has a %
value for the input signal, and the value to display when the input is at that
value. *A Scaling Point set to 100% input ends the scaling sequence.

Display Value

CJC Enable/Disable

Enables/disables internal thermocouple Cold Junction Compensation. If
disabled, external compensation will be required for thermocouples.
The default value is Enabled.

Input Filter Time

Removes unwanted signal noise. Adjustable from 0.1 to 100.0 seconds or
OFF (default = 2s). Use the smallest value that gives acceptable results.

Caution:

Large values slow the response to changes in the process.

Input 1 Calibration

- Sub-menu to calibrate Input 1. Press

to return to Input Menu

Calibration Type

Select the calibration type from base; single or 2-point calibration. Select
single to apply a calibration offset across the entire measured range. Use
2-point to enter calibration offsets at both low and high points of the usable
range

– refer to the User Calibration details on page 70.

Caution:

The default is Base Calibration. For single or 2-point

calibration, the user must enter values to adjust the displayed value
to match a known standard or accurate external reading.

Calibration Offset

The single point calibration offset. Limited by the input span, +Ve values
add to,

–Ve values subtract from, the measured input across entire range.

Calibration Low
Value

The displayed value for the 1

(low) adjustment of 2-point calibration.

Choose a value close to the lowest level used in the application.
