Corrective Actions - Disassemble And Calibration - CME NIKI V4 Service Manual

When receiving a NIKI V4 pump for service the first decision should be made either it's
a user mistake or pump malfunction.
Secondly decide if the failure was caused by the pump or by the administration set.
Than decide if it's a mechanical or an electronic problem. If the malfunction is an
electronic one, check if it's in one of the sensors (air, pressure or motor), if one of the
sensors failed replace the sensor.
If the main PCB failed replace it. Act according to instructions detailed in Section 4.5.
Decision
1.User mistake or pump malfunction.
2.Failure caused by the pump or by the
