Belmont FMS2000 - Patient Leakage Current

7. Preventive Maintenance/System Operational Check-Out
7-91
iv. Repeat the first two (Normal Polarity and Reverse Polarity -
Grounded) with Neutral switch in OPEN position.
v. Install the disposable set and prime with saline and proceed to the
Infuse screen. Press STOP to set the pump at 0 ml/min, not
heating or pumping.
vi. Repeat iii & iv with the FMS2000 in ON mode (power switch ON,
infuse screen displayed, not pumping or heating).
vii. Repeat iii & iv with the FMS2000 infusing and heating at maximum
rate.
viii. All measurements should be <300 µA (for Domestic unit) and
<500 µA (for 230 V unit).
b. Patient Leakage Current:
i Install the disposable set and prime with saline and proceed to the
Infuse screen.
ii. Attach 12 to 16 gauge stainless steel cannula to the end of patient
line and attach the Bio-Tek large clamp to the cannula.
iii. Prime the FMS2000 with saline. Make sure that the entire patient
line including the cannula has been primed.
iv. Repeat a.iii, and a.iv with the FMS2000 in the STANDBY, ON, and
pumping at 500 ml/min modes.
v. Maximum leakage allowable is as follows:
With NORMAL NEUTRAL
Normal Polarity - Grounded (10 µA)
Reverse Polarity - Grounded (10 µA)
Reverse Polarity - Not Grounded (50 µA)
Normal Polarity - Not Grounded (50 µA)
With OPEN NEUTRAL (Note: the system automatically switches
to battery at 50 ml/min.)
Normal Polarity - Grounded (50 µA)
Reverse Polarity - Grounded (50 µA)
