KRK”, then the user can use this particular R-curve to test the SpO
2
function. If the SpO
2
simulator does not contain
“KRK” R-curve, please ask the manufacturer for helping to download the given R-curve into the SpO
2
simulator.
The adjustable units within the monitor such as potentiometers are not allowed to adjust without permission to
avoid unnecessary failures that affect normal application.
It is recommended to use the battery once a month to ensure its power capability and long service life, and
recharge it after run out of its power capacity.
15.3 ECG Verification
The ECG signal may be inaccurate due to hardware or software problems. As a result, the ECG wave amplitude becomes
greater or smaller.
You can print out the square wave and wave scale and then measure the difference between them if necessary. If the
difference exceeds 5%, contact your service personnel.
15.4 Pressure Accuracy Verification
Pressure Accuracy Verification is a function to inspect the accuracy of pressure measurement by the NIBP module inside
the device. Technician or equipment manager should do pressure accuracy verification every half year or year in order to
check if the pressure measurement still conforms to the requirement of product performance. If the deviation is beyond
the declared specification, it is permitted to return it to factory for repair or calibration.
Before verification, please connect the monitor to a precision pressure meter as the reference equipment like a mercury
