KRK”, then the user can use this parcular R-curve to test the SpO
2
funcon. 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 potenometers are not allowed to adjust without permission to
avoid unnecessary failures that aect normal applicaon.
It is recommended to use the baery once a month to ensure its power capability and long service life, and
recharge it aer run out of its power capacity.
15.3 ECG Vericaon
The ECG signal may be inaccurate due to hardware or soware 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 dierence between them if necessary. If the
dierence exceeds 5%, contact your service personnel.
15.4 Pressure Accuracy Vericaon
Pressure Accuracy Vericaon is a funcon to inspect the accuracy of pressure measurement by the NIBP module inside
the device. Technician or equipment manager should do pressure accuracy vericaon every half year or year in order to
check if the pressure measurement sll conforms to the requirement of product performance. If the deviaon is beyond
the declared specicaon, it is permied to return it to factory for repair or calibraon.
Before vericaon, please connect the monitor to a precision pressure meter as the reference equipment like a mercury
pressure meter
