3.7.3.4 Displaying the Timed Value
The Timer reports a time measurement after the timer stops (the Stopped
State).
The Model 931A then displays this value until pressing the
ARM/RESET key (which returns the timer to the Standby state).
During count measurements, the display continuously updates the
count during the measurement cycle. Pressing the ARM/RESET key
resets the count display back to zero, and also re-arms the timer.
3.8 Transducer Testing
Testing transducers with the Model 931A is straightforward using an
external source, such as a calibrator or source and load box. Also perform
live, in-circuit tests. Prior to starting a transducer test the Model 931A
automatically makes a self-calibration.
Use the main measurement inputs to precisely monitor the transducer
input values. Transducer output may be set to either Measured Quantity,
Percent Full Scale, or Percent Error, while simultaneously displaying
the transducer inputs.
This provides a look at the input and output
quantities for better control during the measurement, and fewer chances
for measurement or setup errors.
The Model 931A Transducer input uses accurate, optically isolated
input sections to accept transducer outputs in the range of 0
−
10 Vdc or
0
−
100 mA. Alternatively, transducer custom pulse outputs may also be
tested using the Model 931A Timer A input.
3.8.1 Configuring the Transducer
Press SHIFT > CONFIG to configure transducer measurement section via
a series of menus (a second function of TRANSDUCER). The main menu,
in the series, is the Transducer Configuration menu, which is similar in
appearance to the display shown below:
The following paragraphs describe the functions and capabilities of each
of the Transducer Configuration menu selections.
