Description
Sets the units used for the input low and high settings.
The input value corresponding to 'zero' (4 mA) output.
The input value corresponding to 'full scale' (20 mA) output.
Sets the damping factor for the inbuilt digital filter. Accepts values from 1-99.
The number of samples averaged for each measurement. The effect of this set-
ting depends on the input type. Normally set around 50.
This check box allows you to set 'Input High' and 'Input Low' values in the
software in volts up to 10 V.
Note: The ITXPlus will only accept values up to 10 V if the attenuator switch on
the main board is set to the 10 V setting. If you change the switches you must
recalibrate the voltage input.
Sets the action in case of sensor burn-out or disconnection. Upscale sends the
output to 22 mA, downscale sends the output to 3.7 mA.
Allows you to choose between thermocouple or RTD types. Not shown for other
input types. Note: you can set up your own linearisation tables here by choosing
'user defined'.
Is the input connected in two, three or four wire mode. For RTD and resistance
inputs only. Sets up the lead length compensation.
Description
Sets the output range, normally 4.00 mA to 20.00 mA.

gives the usual proportional output.
Set to direct or reversed. Direct gives the usual proportional output. For reversed
action, the input low value gives a 20 mA output and the high value a 4 mA output.
