Caliper Health
Report
Variable Description Acceptable Range
SMAX Sensor Max Expected output voltage of
the proximeter switch with
the heads unclamped
Air Brng Cal:
7.5-9.0 VDC
GT Caliper:
8.25 VDC ± 1.0
SNOISE Sen Max Noise Standard deviation of the
maximum sensor signal noise
in mv
< 10 mv
SZERO Sensor Zero Expected voltage of the
proximeter output with
nothing in the gap and the
heads clamped. On GT
Caliper, this value is filtered
by the “Sensor Zero Filter
Factor Up/Down”
Air Brng Cal:
3.0-4.0 VDC
Cont Cal
(Al foot):
5.5-7.0 VDC
Cont Cal
(Ti foot):
3.5-5.0 VDC
GT Cal - 2.25
± 1.0 VDC
Sensor Zero Raw The unfiltered value of the
GT Caliper signal with the
probe closed. It is usually
determined from the GT
Caliper calibration report.
On GT Calipers calibration
reports without this variable,
it can be determined by
cleaning the probes and doing
a CLEAN standardize. The
value to use will be the
resulting measured Sensor
Zero.
GT Cal - 2.25
± 1.0 VDC
Pressure Zero
Pressure Zero Top (GT)
Pressure Zero Bot (GT)
This is the output signal of the
pressure transducer when
there is no pressure being
applied to the probe.
GT Cal - 5.0 VDC -
7.0 VDC
Other Calipers -
7.0 VDC - 9.0 VDC
Pressure Top
Pressure Bottom
Pressure at top and bottom
heads of GT Caliper, with air
solenoids engaged, in milli-
bars.
