Applies to 300 psi / 30 bar / 3 MPa and lower ranges only .
Vacuum Range = -14 .5 psi / -1 .0 bar / -1MPa .
**
Full Scale is the numerical value of the positive pressure range .

Includes all effects of linearity, hysteresis, repeatability, temperature,
and stability for one year .
Exposure to environmental extremes of temperature, shock, and/or
vibration may warrant a more frequent recertification period .
APMi modules must be exercised and re-zeroed whenever exposed
to significant changes in environmental conditions to achieve these
specifications . To exercise a module, cycle the module between zero
(ambient barometric pressure) and the pressure of interest . A properly
exercised module will return to a zero reading (or return to the same
ambient barometric reading) .
ACCURACY
CONTINUED
All models indicate vacuum,
but vacuum specification applies only
where specified .
Not recommended for continuous use at high vacuum.
Refer to
XP2i-DP data sheet
for gauges that are intended for continuous high
vacuum use .
The BARO option for the HPC50 Series allows you to toggle between
gauge and absolute pressure using the same APMi module .
