Input Configuration
:
Process Variable Input
Type wFrom various Thermocouple, RTD and Linear inputs. -see
specifications section for full details of input types available.
Engineering Units wSelect display units from: °C; °F; °K; bar; %; %RH; pH; psi or none.
Decimal Point Position wSets the maximum display resolution to 0; 1; 2 or 3 decimal places.
Temperature inputs are limited to 0 or 1 place. 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.
Multi-Point Scaling
Enable
Enables or disables Linear Input Multi-Point Scaling. This feature
allows up to 15 point linearization of mA or V DC input signals.
Scale Range Lower
Limit wFor Temperature inputs, Upper & Lower Limits set the usable span.
Min span = 100 units, max span = range limits -see specs. For
Linear inputs, Upper & Lower Limits define the values shown (-1999
to 9999) when input is at minimum and maximum values. Min span =
100 units. If Multi-Point Scaling is enabled, up to 15 breakpoints* can
scale input vs. displayed value between the linear input scale limits.
*A breakpoint set at 100% input ends the sequence.

CJC Enable/Disable Enables/disables internal Thermocouple Cold Junction
Compensation. If disabled, external compensation will be required for
thermocouples. The default value is Enabled.
Process Variable Offset Trims the measured process value. +Ve values add to, –Ve values
subtract from measured input. Caution: A value other than zero
alters the apparent calibration of the instrument. Use with care!
Input Filter Time Removes unwanted signal noise. Adjustable from 0.0 (OFF) to 100.0
seconds or OFF (default = 2s). Caution: Too large a value will cause
slow response to changes in the process. Use with care!
Auxiliary Input nType wSets the type of signal to be connected to the auxiliary inputs (if
fitted). From: 0-10V; 2-10V; 0-5V; 1-5V, 0-20mA or 4-20mA DC.
Auxiliary input B also supports >2KPotentiometer and 0-100mV.
Auxiliary Input nScaling
Lower Limit wScales the displayed a value (-9999 to 10000) when an auxiliary
input is at or below it’s lower limit (e.g. 4mA for a 4-20mA signal).
Auxiliary Input nScaling
Upper Limit wScales the displayed a value (-9999 to 10000) when an auxiliary
input is at or above it’s lower limit (e.g. 20mA for a 4-20mA signal).
Auxiliary Input nOffset Trims the displayed a value for auxiliary input A or B. +Ve values are
added to, –Ve values subtracted from the measured auxiliary input.
Calibration Reminder
Enable/Disable
Enables or disables the display of Calibration Reminder at start-up
(repeated daily thereafter), if the due date has passed –Available on
the Recorder version only
Calibration Reminder
Due Date
Sets the due date for the Calibration Reminder -Available on the
Recorder version only
