Test
1. Electrical safety tester test: Check the electrical safety tester meter rises to a value within the
indicated 'test' region.
2. Supply: Note the mains supply voltage reading.
3. Insulation: Press the test switch on the electrical safety tester and note the insulation resistance
reading.
4. Earth Continuity: put the test probe on one of the two screws adjacent to the mains inlet at the
rear of the ventilator and repeat the test. Note the meter reading.
5. Earth/equipotential continuity: Place the electrical safety tester test probe on the equipotential
connector at the rear of the ventilator. Press the test switch and again note the meter reading.
6. Normal Earth Leakage: Set the electrical safety tester Normal/Operate/Reverse switch to
Normal and note the earth leakage current. Then set to Reverse and again note the earth
leakage current.
7. Supply o/c Earth Leakage: Obtain the two earth leakage readings as in operation 6. (Normal
and Reverse.
5.4 Fresh gas leak test
Connect spirometry tubing 10110089 from TJ92 to the fresh gas connections on the rear of the
ventilator. Each side of the circuit is checked by pressurising it to 80 mmHg and checking that
the pressure is maintained..
Fresh Gas Alarm
Set ventilator to Tv 0.5, BPM 12, I:E 1:2. The fresh gas alarm should go off when the fresh
gas flow is greater than 11.8 LPM.
Set ventilator to Tv 0.25, BPM 12, I:E 1:2. The fresh gas alarm should go off when the fresh
gas flow is greater than 5.9 LPM.
5.5 Printer Output Check
Connect the 8500 to the PC via the calibration port on rear the of the 8500 ventilator.
Run 8500.ht on the PC. Switch the ventilator ON and check that the calibration data is
displayed on the dumb terminal.
