Note:
Accuracy includes all effects of linearity, hysteresis, repeatability, temperature, and stability for one year.
Exposure to environmental extremes of temperature, shock, or vibration may warrant a more frequent period.

Vacuum Floor Term (VFT):
For 16 & 36 PSI: VFT = 0.004 PSI
For 300 PSI: VFT = 0.01 PSI
For 1 or 2 bar, & 100 or 200 kPa: VFT = 0.0003 bar or 0.03 kPa
For 20 bar or 2000 kPa: VFT = 0.001 bar or 0.1 kPa
Vacuum operation is not specified for 600 PSI (40 bar/4000 kPa) models and higher. However, all models can be safely connected to vacuum.
The 30 Series calibrator is not recommended for continuous use at high vacuum. Refer t
data sheet for gauges that are intended for continuous
high vacuum use.
Temperature

Battery should be removed if stored for more than one month.
SI (metric) Versions
“SI” is the French acronym for the International System of Units. 30 Series products with “KPA” in the part number are intended for markets where only SI units
are permitted. Therefore, these models only have kPa and/or MPa, bar and/or mbar available.
