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).

Equipment Type Minimum use specifications Purpose
Calibration standard (absolute) Range:
35 mbar to 2000 mbar absolute.
Expanded uncertainty (k = 2):
32ppm of r0.007
mbar(0.0032% of r0.70 Pa) Calibration
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.
