Source Scale
This feature lets you scale the output in accordance
with the input requirements of a particular process
instrument’s response. Percent of scale works for
linear-responding transmitters, or square-root
responding transmitters.
Linear-Responding Transmitters
1. If necessary, press M for SOURCE mode.
2. Select a source function (m, v, h, q,
t, or p) as previously described and enter
a value.
3. Press the
Scale softkey.
4. Select
% from the list.
5. Use the numeric keypad to enter the 0% of scale
value (
0% Value).
6. Press e.
7. Use the numeric keypad to enter the 100% of
scale value(
100% Value).
8. Press the
Done softkey.
Percent of scale remains in effect until you change to
another source function or press the
Scale softkey
and select another scale mode.
Square-Law Process Variables
When you select √ within scaling, the calibrator
output value is the percent value entered, squared,
and converted to engineering units.
1. If necessary, press M for SOURCE mode.
2. Select a source function (m, v, h, q,
t, or p) as previously described.
3. Press the
Scale softkey.
4. Select
√ from the list.
5. Use the numeric keypad to enter the 0% of scale
value (
0% Value).
6. Press e.
7. Use the numeric keypad to enter the 100% of
scale value(
100% Value).
8. Press e.
