Setting up RTD Inputs

Entering the Zero Cutoff

1-20
Option cards with RTD inputs have a temperature range of –100° to
350°C. Complete the following steps to set up the two RTD inputs of
an option card installed in Slot x:
1. Press [F1] to set up RTD input A or
Note: The setup of RTD input A is used as an example. Identical
procedures would be used to set up RTD input B.
2. Enter a label of up to eight characters and press
3. At the Input Measurement prompt, press
RTD input A and return to the previous prompt, or press
TEMP to enable RTD input A.
4. Enter the Zero Value for the low end of the chosen input range and

6. Press [F1] - [F2] to set up another input or press
another slot for set up.
For instructions on setting up additional inputs and/or outputs
proceed to the appropriate section. Otherwise, press
to the main I/O menu prompt.
Near zero flow, the Model GF868's readings may fluctuate due to
small offsets caused by thermal drift or similar factors. To force a
zero reading when there is minimal flow, enter a zero cutoff value as
described below:
1. At the main I/O menu prompt, press
2. Enter the desired Zero Cutoff value and press the
value of 0.1 ft/s (0.03 m/s) is recommended, but values from 0–1
ft/s (0–0.3 m/s) are acceptable. The menu returns to the main I/O
prompt.
