Electronics International MVP-50P - Manual (Page 58)

“Probe:” This field displays the Probe assigned to the EDC Input selected above.
“Raw Input Value:” This field displays the value of the uncalibrated signal measured on the EDC Input selected
above. This value is transmitted to the MVP from the EDC.
“Processed Value:” This field displays the value of the calibrated signal measured on the EDC Input selected
above. The Raw Input Value is calibrated by the calibration parameters listed below.
“EDC Units:” This field displays the processed units, which may
not be the same as the displayed units. The MVP performs a
conversion, changing the processed units to displayed units. You
can select the displayed units in Screen # 3.
Calibration Parameters: The Raw Input Value read from the
EDC is processed (in sequence) by the following calibration
parameters:
“Gain:” The Raw Input Value from the EDC is multiplied by
the number in this field. An Interim Value is produced.
Values over one should not be used.
“L.S.B. (shift right):” This field determines how many
binary logic shift right processes are performed on the Interim
Value. Each shift operation divides the Interim Value by 2.
“Multiplier:” The Interim Value is multiplied by the value in this field. The Multiplier may be set to 1, 2, 5,
10 or 100. The Multiplier sets the resolution (i.e., a multiplier of 2 sets the resolution to 2 counts).
“Reference:” The Interim Value may be referenced to another Function. The value of the Function selected
in this field will be added (+) or subtracted (-) from the Interim Value. Differential measurements can be made
by subtracting one Function from another. Temperature measurements based on thermocouple probes must
be temperature compensated by referencing the “T. COMP” (temperature compensation) Function.
“Allow Negative Readings:” Negative readings should not be allowed on functions such as RPM, M.P.,
most pressures, fuel levels, etc. If negative readings are not allowed, negative values will be displayed as zero.
“Filter:” The Interim Value may be filtered. A filter increases the response time (shown in the “seconds =”
field) and reduces jumping.
“Dejitter Level (FFT):” A unique dejitter algorithm may be applied to the Interim Value. A Dejitter
algorithm removes jumpy readings without increasing response time.
“Truncate (# digits):” The last one or two digits on the Interim Value may be truncated (displayed as zero).
“Decimal Places:” This field only allows you to place a decimal point in the display. It does not change the
calibration of the Interim Value.
