Pump Leakage Test With Pumps Requiring Negative Pressure To Start; Electrode Leakage - GE KISS Service Manual

Pump Leakage Test with Pumps Requiring Negative
Pressure to Start
Start the pump by pulling gently on the syringe piston. Then switch off the negative
pressure pump (ECG recorder or power supply unit): The drop in negative pressure
must not exceed max. 1 mmHg/s (1.33 mbar/s).
If this value is not observed, the pump must be replaced (ECG recorder/acquisition
module (acq. module) or the power supply unit).
If the reading is correct, there must be a leak in the distributor or regulator. The
distributor incl. regulator should be replaced. See
page 25.

Electrode Leakage

Start the pump by pressing the electrode to the test plate (part no. 303 444 90)
Negative pressure adjusted to maximum: max.150...195 mmHg (200...270 mbar)
Negative pressure adjusted to minimum: min. 37... 60 mm Hg (50...80 mbar)
Each electrode plus lead is tested in sequence.
(This can be always be conducted at the same distributor slot).
If these values are not observed, there is leakage at the electrode body/suction
cup interface or at the plug-in connection to the electrode lead.
