or calibrators with firmware version 2.0 and higher
, some units will not be displayed due to limitations on display re
solution. F
or calibrators with earlier versions of firmware, the calibrator
will attempt to display a value, but the display will be excessively noisy to be useful. In all cases, best practice would proh
ibit the use of small engineering units such as mm H2O with high pres-
sure range sensors.
• Proof pressure - maximum allowable pressure without a shift in calibration
• Burst pressure - sensor damaged or destroyed; some risk of personnel injury
• Compound ranges - the data for the 15 PSI range also applies to the -15 to +15 PSI compound range; the data for the 30 PSI ra
nge also applies to the -15 to +30 PSI compound range.
• Absolute ranges - the data for the 15, 30, 50, 100 and 300 PSI ranges also applies to the absolute pressure versions of those
ranges.
