Equipment Type
Calibration standard (absolute)
All traceable to national standards.
If a calibration standard with higher uncertainty is used, the ADTS accuracy will be degraded and may exceed
the ADTS sales data sheet specification.
Table 4-3: Calibration equipment uncertainty

Suggested two-point calibration adjustment points

Calibration points are nominal pressures to allow for slight differences due to primary standard
weights and actual corrected pressure calculations.
- Ps: two point cal points = 1st point is 1128mbar (FS) followed by 92mbar (suggest to be done in
this order).
- Pt: two point cal points = 1st point 92mbar followed by 1997mbar (FS) (suggest to be done in
this order).
