NOTE: The measurement units that appear in these
prompts are those selected in the global-system menu
earlier in this section.
5. Enter a flow rate value for the zero (low) end of the
analog output range and click [next item].
6. Enter a flow rate value for the full (high) end of the
analog output range and click [next item].
After responding to the above prompt, the meter returns
to step 1. Click [exit page] to proceed to another menu
or option.
Option card analog inputs
Complete the following steps to set up the analog inputs
of an option card installed in slot 1 (refer to Figure 58 on
page 83 ):
1. Double-click on the desired input (A, B, C or D).
NOTE: The setup of input A is used as an example. Identical
procedures would be used to set up the remaining inputs.
2. Enter a label of up to eight characters for input A and
click on [next item].
3. Double-click on off to disable input A and return to step
1, or on temp or spec to designate it as a temperature or
special input.
•
Off
If OFF was selected to disable input A, the meter returns
to the input prompt in step 1. Double-click on another
input, or click [exit page] to move to another menu.
• Temp or presr
If temp or presr was selected to set up input A as a
live temperature or pressure input, complete steps
4 and 5 below:
4. Enter a value for the base (low) end of the analog input
range and click [next item].
5. Enter a value for the full scale (high) end of the analog
input range and click [next item].
After responding to the above prompt, the meter returns
to step 1. Click [exit age] to proceed to another menu or
option.
•
Spec
If spec was selected to set up input A as a live special
input, complete steps 6 through 9 below:
6. Enter a name for input A and click [next item].
