The following table provides a description of the various station signals.
Station Signals
S IGNAL D ESCRIPTION
Time Displays the time reference signal derived from the internal clock that
increments continually. This signal exists to support data acquisition by test
program applications, such as Basic TestWare and MultiPurpose TestWare. It is
not practical to monitor the time signal with an external readout device.
Rollover Time Displays the time reference signal derived from the internal clock that resets
every hour. Like the time signal, this signal exists to support data acquisition
by test program applications. It is not practical to monitor the hourly rollover
time with external readout devices.
Output Displays the test control signal sent to the valve driver in volts.
Command Displays the program command signal in engineering units.
Comp. Cmd Displays the value of the compensated command signal in engineering units.
This signal is only valid when using PVP, PVC, AIC, APC, or ALC
compensators.
Count Displays the number of segments played out so far in the selected control
channel. When using a Station Manager meter, this signal is only available for
the Timed meter.
Error Displays the error signal in engineering units. The error is the difference
between the command signal and the sensor feedback signal.
Abs. Error Displays the absolute value of the error signal in engineering units.
