Input channel setup
The screens at 520 and 521 give direct access to the parameters controlling the two input
channels. There is no need to access these screens for basic gauge operation. The
calibration functions automatically update these values as necessary.
Note: Personnel that are unfamiliar with the system should not access these screens.
Changing values at these address locations can adversely effect the operation of the gauge.
Each of the screens (520 and 521) hold 50 items numbered 0 to 49. Please refer to the
tables in Appendix I, page 130 for a complete listing of each item. Refer to Figure 24 for
jumper configurations for the frequency input Channel #1.

520 Frequency input channel #1, primary sensor signal (frequency
only)
This memory block processes frequency input parameters such as:
•
Signal type (direct/inverse)
•
Source decay counts
•
Raw, filtered, normalized, and calibrated counts
•
Gain factors
521 Frequency input Channel #2, tachometer/speed input
This memory block processes frequency input signals from Channel #2 similar to Channel
#1. Channel #2 input is limited to optional equipment, such as, the tachometer.
It is possible, in limited application needing two sensors, for the raw count signal at Channel
#2 to come from a secondary sensor. The counts add to those coming into Channel #1 from
the primary sensor to obtain a total raw count, before signal processing. You cannot use this
feature to process two separate measurements. Refer to Figure 24 for jumper configurations
for the Frequency input Channel #2.
