Welch Allyn Spot Vital Signs - User Manual - Manual (Page 35)

Directions for Use 27
• Setra Pressure Meter, calibrated accuracy of ±0.1 mmHg (part no. 2270-01)
• Netech Pressure Meter, calibrated accuracy of ±1.0 mmHg (part no. 200-2000IN)
Use of other pressure measurement standards is acceptable, provided they have an
accuracy of better than ±3 mmHg, are traceable to NIST, and have a current calibration.
Note Do not take more than 3 minutes to take the readings, as the Spot Vital Signs will
open its pressure relief valve as a safety feature. If this occurs, turn the device off
and start over.
The Spot Vital Signs has the option to measure pressure in kPa units. If the device
is set to kPa instead of mmHg, temporarily set the device to mmHg units or
convert all pressures to kPa units.
