Arbiter Systems 931A, Руководство по эксплуатации

Страница: 85 / 161

ˆ
“Measured Quantity” displays the value present at the Model 931A
measurement inputs in actual measurement units (e.g. volts, amps).
ˆ
“Percent Full Scale” displays the value present at the Model 931A
measurement inputs as a percentage of full-scale. Full-scale is defined
by the lower and the upper limit of the currently selected input range
(see Section 3.8.1.3 for a description of Input Ranges).
3.8.1.6 Display Output As
Select Display Output As from the Transducer Configuration menu to
display the following sub-menu:
ˆ
“ Measured Quantity ” sets the Model 931A to display the actual
value measured at the output of the transducer under test (i.e., volts
or milliamperes).
ˆ
“ Percent Full Scale ” displays the measured value (at the output
of the transducer under test) as a percentage of full-scale. Full-scale
is defined by the lower and the upper limit of the selected output
range. Does not apply for Custom Pulse.
ˆ
“ Percent Error ” displays the measured error of the transducer
based on the measured input and output quantities.
To properly utilize the Percent Error feature, enter the following: (1)
the upper and lower transducer input quantities and (2) the upper
and lower transducer output range limits. Setting the output range
limits are critical for transducers having a lower output range limit of
other than zero. For example a typical transducer may have a 4
−
20
mA output. With such a transducer, zero at the input corresponds
to 4 mA at the output.
