Table 3. Configuration Menu Options Setting Description Blood Pressure Calibration Prepares the Spot Vital Signs for calibration. Only qualified personnel should verify the Displays “Cal” Spot Vital Signs blood pressure calibration. For more details, see “Blood pressure calibration” on page 27.
Subtract the rated accuracy of the pressure measurement standard from the "3 mmHg rated accuracy of Spot Vital Signs. This is the pass/fail criteria to determine if the device is within calibration. If the differences between Spot Vital Signs and the pressure measurement standard are within the pass/fail criteria at all specified pressures, then the device is within calibration.
Functional overview Welch Allyn Spot Vital Signs NOTE: The pass/fail criteria for the blood pressure calibration check depends upon the accuracy of the pressure measurement standard used. • If the pressure measurement standard used is rated with an accuracy of ±0.1 mmHg, the pass/fail criteria is ±2.9 mmHg in order to guarantee that the instrument under...

Disassembly and repair Welch Allyn Spot Vital Signs 4. Carefully slide and center the foam sleeve over the NIBP filter. 5. Remove the open-ended tubing from the pump and replace with the pump filter assembly. Confirm proper pump fitting.
An external power supply charges the battery and can operate Spot Vital Signs at the same time. The external power supply provides the Spot Vital Signs with up to 1000mA at 7.2VDC. As the battery charges, the energy required to charge it decreases and the external power supply voltage rises to 8 VDC while supplying 750mA.
The battery supplies power to the SpO through a +5V linear regualtor (U322). If there is no SpO module connected to the Spot Vital Signs main board the SpO2 power supply is disconnected. LCD power The main CPU supplies power to the LCD module through the J307 connector, and the FET Q312 and comparator U324A control the backlight.
If a Version 1 (serial number less than 200705000) is sent in for updates or repair to the main printed circuit board, it is necessary to upgrade the keypad and front housing/bezel assembly. The Spot Vital Signs is then referred to and functions as a Version 2. See Table 1 on page 1 for the specific version differences.
