300, 250, 200, 150, 100, 50 (60 for US) and
0 mm Hg.
Note: Your ability to measure the accuracy of a gauge
depends upon the sensitivity of the pressure standard
you use for the calibration procedure.
If using a manometer (mercury column or aneroid
gauge) rated at ± 3.0 mm Hg, an undetectable
error of up to 6.0 mm Hg is possible. If using a
device (e.g., digital pressure standard) rated at
± 0.1 mm Hg, an undetectable error of up to only
3.1 mm Hg is possible.
Welch Allyn recommends using as sensitive as
possible a pressure standard when performing
calibration checks. A Setra Pressure Meter (part
no. 2270-01), which is calibrated for ± 0.1 mm Hg,
or Netech (part no. 200-2000IN), which is
calibrated for ± 1.0 mm Hg, works well for this
application. Welch Allyn offers each meter, contact
distributor.
