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
D
+
R
to return to Input Menu
Input Type w 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 w
Select display units from: °C; °F; °K; bar; %; %RH; pH; psi or none.
Temperature sensor inputs are limited to °C; °F
Decimal Point
Position w 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 n 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 n
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

R
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
st
(low) adjustment of 2-point calibration.
Choose a value close to the lowest level used in the application.
Calibration Low
Offset The adjustment value for the 1
st
(low) point when using 2-point calibration.
+Ve values add to,
–Ve values subtract from measured input at this point.
Calibration High
Value The displayed value for the 2
nd
(high) adjustment of 2 point calibration.
Choose a value close to the highest level used in the application.
Calibration High
Offset The adjustment value for the 2
nd
(high) point when using 2-point calibration.
+Ve values add to,
–Ve values subtract from measured input at this point.
