You can change several device operating parameters in the Internal Configuration Mode.
When changed, these settings become the default power-up settings. You will also see
non-changeable device configurations for technical service purposes.
To enter the Internal Configuration Mode:
1.
Turn the Spot Vital Signs off (
).
2.
Press and hold the Blood Pressure Start/Stop (
) and Power (
) buttons. The
device enters the Internal Configuration Mode and displays the software version.
If the device displays E38, press the Next Patient/Clear/Cancel (
) button to
cancel the error.
3.
Press the Mode (
) button to cycle through the Internal Configuration menu until
you see the date option displayed on the screen.
4.
Use the Next Patient/Clear/Cancel (
) or Blood Pressure Start/Stop (
)
buttons to change the default setting.

Welch Allyn Spot Vital Signs
Checking the Blood Pressure Calibration
The Welch Allyn Spot Vital Signs is manufactured to the highest industry standards for
quality and accuracy. The device is manufactured using calibrated pressure standards
traceable to NIST (National Institute of Standards and Technology). Welch Allyn
recommends that blood pressure calibration for the Spot Vital Signs is checked on an
annual basis using the following procedure.
Put the Spot Vital Signs into its blood pressure calibration check mode. In this mode, the
device continuously displays the measured pressure and closes the pressure release
valve.
1.
Enter the internal configuration mode (see “Internal Configuration” on page 19).
2.
Press the Blood Pressure Start/Stop button to close the device’s internal valve to
apply an external pressure.

Connect the Spot Vital Signs as shown to
a calibrated pressure meter (verify
certificate is traceable to the National
Institute of Standards and Technology. The
pressure meter testing the Spot Vital
Signs must have an accuracy of better
than ±3 mmHg. Use a fixed volume or a
blood pressure cuff wrapped around a
cylinder for the stabilization volume.
4.
Pressurize the Spot Vital Signs to slightly
above 250 mmHg. Bleed the pressure to
approximately 250 mmHg. Clamp and
record the pressure reading and the
measurement standard. Repeat this step for 150 and 50 mmHg (approximate).
5.
Calculate the difference between the readings. 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 or
not. 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.
If the Spot Vital Signs needs re-calibration the procedures are included in the Spot Vital
Signs Service Manual. Alternatively, send the device back to Welch Allyn for calibration by
contacting Technical Service.
Welch Allyn recommends using a pressure meter that is as accurate as possible when
performing calibration checks. Welch Allyn offers two different pressure measurement
standards for use:
Note
The pass/fail criteria for the blood pressure calibration check depends upon the
accuracy of the pressure measurement standard used. For example:
•
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 test is within ±3 mmHg of NIST.
•
Welch Allyn Spot Vital Signs Monitor Service Manual
If the pressure measurement standard used is rated with an accuracy of ±1.0
mmHg, the pass/fail criteria is ±2.0 mmHg in order to guarantee that the
instrument under test is within ±3 mmHg of NIST.
