1. CALIBRATION

CALIBRATION CHECK

Check the Temperature, Humidity and Oxygen probes correct operation, at least every three months, in
order to make sure of the proper operation of the device and to protect the newborn’s health. The check

of the probes reading is done by using the two Reference Simulators, produced by Ginevri s.r.l.,
that, in case of malfunctioning, are necessary for the re-alignment of the probes.

The Reference Simulators are optional devices that can be ordered to Ginevri s.r.l., with the part numbers
10487A60 and 10875A60.
Perform the following steps to check the probes calibration.

TEMPERATURE PROBES

1. Switch the equipment off and disconnect it from the power supply

2. Disconnect the probe assembly connector from the control panel and replace it with the Reference
Simulator

3. Connect the equipment to the power supply and switch it on.

4. Set the reference simulator on AIR 1 at 25,0°C (potentiometer PROBES on A1 and potentiometer
TEMP °C on 25°C). The temperature display TEMP°C should show the value 25,0°C ± 0,2°C.

5. Set the reference simulator on AIR 1 at 32,0°C. The temperature display TEMP°C should show the
value 32,0°C ± 0,2°C.

6. Set the reference simulator on AIR 1 at 33,0°C. The temperature display TEMP°C should show the
value 33,0°C ± 0,2°C.

7. Set the reference simulator on AIR 1 at 36,0°C. The temperature display TEMP°C should show the
value 36,0°C ± 0,2°C.

8. Set the reference simulator on AIR 1 at 38,0°C. The temperature display TEMP°C should show the
value 38,0°C ± 0,2°C.

9. Set the reference simulator on AIR 1 at 40,0°C. The temperature display TEMP°C should show the
value 40,0°C ± 0,2°C.

10. Set the reference simulator on AIR 2 at 25,0°C (potentiometer PROBES on A2 and potentiometer
TEMP °C on 25°C).. The temperature display TEMP°C should show the value 25,0°C ± 0,2°C.

11. Set the reference simulator on AIR 2 at 32,0°C. The temperature display TEMP°C should show the
value 32,0°C ± 0,2°C

12. Set the reference simulator on AIR 2 at 33,0°C. The temperature display TEMP°C should show the
value 33,0°C ± 0,2°C

13. Set the reference simulator on AIR 2 at 36,0°C. The temperature display TEMP°C should show the
value 36,0°C ± 0,2°C

14. Set the reference simulator on AIR 2 at 38,0°C. The temperature display TEMP°C should show the
value 38,0°C ± 0,2°C

15. Set the reference simulator on AIR 2 at 40,0°C. The temperature display TEMP°C should show the
value 40,0°C ± 0,2°C

16. Set the reference simulator on MAX TEMP (potentiometer PROBES and deviator on MAX TEMP)
and on VAR (potentiometer TEMP °C on VAR), set the potentiometer VAR on 39,0°C and check that
MAX TEMP alarm has not been activated. Set the reference simulator on 40,0°C and check that
MAX TEMP alarm is activated.

OXYGEN PROBE

17 During normal operation, both in AIR and in SKIN mode, connect the reference simulator

oxygen/humidity to the oxigen probe inlet.
18 Adjust the selector of the reference simulator on MEASURE mode.
19 Check that the display % OXIGEN indicates CA blinking.
20 Adjust the selector of the reference simulator on CAL mode and wait for about 30 sec. before doing

the calibration.
21 During the calibration, check that CA on the % OXIGEN display is not blinking anymore.
22 When the calibration is finished, check that the % OXIGEN display shows 21%.
23 Set the reference simulator at 98% and check that the % OXIGEN display shows 98% ± 0%.
24 Set the reference simulator at 21% and check that the % OXIGEN display shows 21% ± 0%.

HUMIDITY PROBE

25 Connect the oxygen/humidity reference simulator to the PROBE ASSEMBLY inlet.
26 Check that the led HUMIDITY probe is switched off.
27 Set the reference simulator at 90%. The % HUMIDITY display should show the value 90% ± 0%on
28 Set the reference simulator at 60%. The % HUMIDITY display should show the value 60% ± 0%.
29 Set the reference simulator at 30%. The % HUMIDITY display should show the value 30% ± 0%.

If any malfunction is detected, the probes that have shown a malfunction have to be calibrated. The
calibration procedure can be done by means of the same device used for the calibration check and
following the procedure below.

AIR 1 PROBE CALIBRATION

The probes calibration has to be performed as follows:
1 Switch the equipment off and disconnect it from the power supply.
2 Disconnect the probe assembly connector from the control panel and replace it with the Reference

Simulator.
3 Connect the equipment to the power supply and switch it on.
4 Set the Reference Simulator on AIR 1, MUTE, TEMP =25°C.
5 Set the multimeter on mV voltage in cc and connect the negative terminal on pin 2 of J5 and the

positive terminal on TP1 Of the microprocessor board (see related LAYOUT)
6 Adjust the trimmer R29 until the measured value is 1060mV ± 1mV.
7 Disconnect the multimeter and set the reference simulator on TEMP = 36°C.
8 Adjust the trimmer R28 until the AIR display of the display board shows the value 36,0°C ± 0,2°C.
9 Set the TEMP selector of the reference simulator on each value and check the calibration for all of

them, except for 0°C and 40°C, by reading the value shown on the AIR display. Every value must be

hold for at least 10 sec. and the following deviations are admitted:

25,0°C ± 0,2°C

29,0°C ± 0,2°C
33,0°C ± 0,2°C
34,0°C ± 0,2°C
36,0°C ± 0,2°C
38,0°C ± 0,2°C

AIR 2 PROBE CALIBRATION

10 Switch the equipment off and disconnect it from the power supply.
11

Disconnect the probe assembly connector from the control panel and replace it with the Reference

Simulator.

12

Connect the equipment to the power supply and switch it on.

13

Set the Reference Simulator on AIR 2, MUTE, TEMP = 36°C.

14

Adjust the trimmer R31 until the AIR display of the display board shows the value 36°C ± 0,2°C.

15 Repeat step 9 with the reference simulator for both Air1 and Air2.

MAX TEMP CALIBRATION

16 Set the Reference Simulator on MAX TEMP (potentiometer PROBES and deviator on MAX TEMP),

TEMP = 40°C.
17 The MAX TEMP
18

Adjust the trimmer PT 101 of the display board until the balance point between activation and

should be active.

disactivation of the alarm is reached. Adjust the trimmer so that the alarm is activated.

19 Set the reference simulator on VAR. Rotate the potentiometer on the reference simulator until the alarm is

activated, without moving the potentiometer set the reference simulator on AIR1. Check that the Air display

shows the value 40.0°C ±0.1°C. Repeat step 18, if needed.
20 Check that at every activation of the alarm MAX TEMP the relay RL2 is disactivated and the led bar showing

the heating percentage indicates zero..

SKIN CALIBRATION

21 Set the Reference Simulator on SKIN, MUTE, TEMP = 36°C.
22

Adjust the trimmer R30 until the SKIN display of the display board shows the value 36,5°C ± 0,2°C.

23 Repeat steps 9 to 15 and steps 21 and 22 with the reference simulator for both Air1 and Air2 (the Skin reading

has to be seen on the Skin display).

HUMIDITY CALIBRATION

24 Connect the oxygen/humidity reference simulator to the proper connectors placed on the control panel. Set the

oxygen/humidity reference simulator on HUM = 0%. Connect the multimeter, select mV cc, with negative
terminal on pin 2 and the positive terminal on pin 5 of U12 of the microprocessor board. Adjust the trimmer

PT1 placed on the display board until the value measured by the multimeter is 0mV ± 0,2mV.
25 Set the oxygen/humidity reference simulator on HUM% = 90%.
26 Adjust the trimmer PT1 placed on the display board until the HUM display on the display board shows the

value 90.

27 Check the calibration on the remaining set values HUM = 30% and HUM = 66%. There is no particular

deviation requirement.

OXYGEN CALIBRATION

28 Connect the oxygen reference simulator to the proper connectors placed on the control panel, and set it on

ZERO.

29 Set the multimeter on mV cc and connect the negative terminal on pin 2 of J5 and the positive terminal on pin 6

of U12 of the microprocessor board. Adjust the trimmer PT4 of the display board until the measured voltage is
0mV ± 2mV. If necessary adjust the trimmer PT3 on the display board previously.

30 Set the oxygen reference simulator on OXI% = 21% and adjust PT3 until the value measured by the multimeter

is 980mV ± 5mV.

31 Set the oxygen reference simulator on OXI% = CAL and check that after this value is hold for about 30 sec.

from the CAL indication, the OXI display shows the value 21.

32 Set the oxygen reference simulator on OXI% = 98% and adjust PT3 until the value shown on the OXI display

is 98.

33 Set the oxygen reference simulator on OXI% = 21% and check that the value shown on the OXI display is 21.

If any deviation is present, then repeat steps 28 to 33 until the values 21% e 98% are obtained.
