Test
Insert a primed set into the pump. Occlude the set. At 0.7 bar the high
pressure alarm will be activated, in case the high pressure alarm level
was set to high.
0.5 bar correspond to normal setting and 0.3 bar to low.
The default pressure setting is 20, this number is automatically
registered in the pump's memory.
Auto pressure calibration can be performed in the following way.
Switch pump on while the arrow down key is continuously pressed.
The display will show 'code', scroll down using the arrow key to 8888.
Press run/hold key to confirm.
The display will show 'auto cal'.
Load a NIKI V4 primed administration set into the pump.
Connect a pressure gage at the end of the administration set.
Once the pressure gage shows a pressure of 0.7 bar press the
run/hold key. The display will show the pressure calibration and will
automatically register that value in the pump memory.
The pressure setting, as all other settings, is registered indefinitely in
the pump's memory, until changed by the user.
Enter 'code' the same way as described above. Set CODE 3 press the
run/hold key, the display will show the actual pressure – the number
displayed should be between 80 to 100.
Press the run/hold key again, the display will show the delta pressure
setting. Accept or change using the arrow keys.
Press the run/hold key to continue, the display will show the absolute
pressure level (should be 250).
Insert a NIKI V4 primed set into the pump. Occlude the set.
Check on JP8 P5 frequency increase by (number x16 › 300 HZ) in case
to frequency increase the sensor is either broken.
Check voltage drop on R45 using an avometer.
Check battery voltage on connector JP8 P12.
Test pump performance on battery at a rate of 125 ml/hr for minimum
of 12 hours.
