3.8.5.2
Determine the Transducer Type
Most transducers with contact (or pulse) outputs use either an electrome-
chanical or a solid-state relay. If the transducer has an electromechanical
relay at the output, it is important to use the Debounce feature on the
Model 931A. Otherwise, do not use it.
3.8.5.3
Configuring in the Transducer Menu
Press SHIFT then CONFIG to access the Transducer Configuration menu.
Set each of the six categories in the Transducer Configuration menu that
best fits the transducer being tested. Use the arrow keys and ENTER to
make and confirm selections. As each of the six categories is setup, the
arrow cursor moves down to the next category.
The sample menu shown below pertains to a 3-phase power transducer
illustrated in Figure 3.18.
Make these selections as follows (as shown in the screen above).
1.
Input Mode
– select the Phase, number of Wires and Elements
(e.g. 3P 4W 3E).
2.
Input Type
– select Volts, Phase, Power, Volt-Amps, Amps,
Frequency, Vars, or Power Factor (e.g. Power).
3.
Input Range
– select the transducer range being tested (e.g. 0 -
1500).
4.
Output Range
– this selects the Custom Pulse feature. Choose
Custom Pulse (only) for this menu item. Note that after Custom
Pulse is selected (under the Transducer Output menu) the bottom
line will clear and read ”Watt-hours per pulse = 0.00000”. Use the
right and left arrows to move the cursor and the up and down arrows
to change the digit value. 100 (watt hours per pulse) is the largest
acceptable value
5.
Display Input As
– select either Measured Quantity or Percent
Full Scale (e.g. the above settings will display Measured Quantity in
kWatts).
