Measurements in Percent of Scale
This feature lets you scale the measurements in
accordance with a particular process instrument’s
response. Percent of scale works for linear-output
transmitters or square-law transmitters such as
differential pressure transmitters that report flow rate.
Linear-Output Transmitters
1.
If necessary, press M for MEASURE mode.
2.
Select a measurement function (m, v, q,
t, or p) as previously described.
3.
Press the
Scale softkey.
4.
Use the numeric keypad to enter the 0% of scale
value (
0% Value).
5.
Press e.
6.
Use the numeric keypad to enter the 100% of
scale value (
100% Value).
7.
Press e.
8.
Leave
Mode set to %.
9.
Press the
Done softkey.
Percent of scale remains in effect until you press the
Scale softkey again or change to another
measurement function.
Square-Law Process Variables
When you select within scaling, the calibrator takes
the square root of its input and displays the
measurement in percent. For example, when
connected to the output of a delta-pressure
transmitter, the calibrator reading is proportional to
flow rate.
1.
If necessary, press M for MEASURE mode.
2.
Select a measurement function (m, v, q,
t, or p) as previously described.
3.
Press the
Scale softkey.
4.
Use the numeric keypad to enter the 0% of scale
value (
0% Value).
