3) Pump the pressure to nearly 100 mmHg. Compare the pressure displayed
on the screens of the device and the reference manometer. For example, the
“100 .9” displayed on the device stands for “100.9 mmHg.”
4) Pump the pressure to nearly 200 mmHg. Compare the pressure displayed
on the screens of the device and the reference manometer. For example, the
“201.0” displayed on the device stands for “201.0 mmHg.”
5) Pump the pressure to nearly 300 mmHg. Compare the pressure displayed
on the screens of the device and the reference manometer. For example, the
“301.2” displayed on the device stands for “301.2 mmHg.”
6) If the difference between the device and the reference manometer at any
calibration point exceeds ±3 mmHg plus the stated accuracy of the reference
manometer, contact ADC to obtain calibration service.
