2.2.6 Pressure Calibration Procedure
Step-1
To enter into the calibration procedure, press
the STATIC and MEDIUM key together while
the power is off. Then turn the power on.
Step-2
When the LED lights up, this means you
have entered the calibration procedure.
When the HEAVY LED lights up, prepare
to perform air tube open pressure
calibration.
Step-3
The compressor is now working. Make sure
that the two air outlets have open
connection flow.

12
Step-4
Press the HEAVY key to record the open
pressure. The HEAVY LED light will turn off,
and the compressor will stop working. This
means the open pressure calibration is
complete. When the MEDIUM LED lights up,
you may begin to perform the next
procedure.
Step-5
Now the MEDIUM Key LED is lit up, you are
ready to enter into the low-pressure
calibration procedure.
Stpe-6
Provide a constant and stable 30mmHg
pressure from an external source.

13
Step-7
Press the MEDIUM key to record the low
pressure. When the MEDIUM key LED
goes out, this means the low-pressure
calibration is completed. Next the LIGHT
key LED will light up. If the providing
pressure from the external source is less
than or equal to the open pressure
setting, the system will automatically
revert back to Step-2 and requires
calibration again.
Step-8
When the LIGHT key LED lights up, you
are ready to begin to perform the
high-pressure calibration.
Step-9
Provide a stable 60mmHg pressure from
an external source.

14
Step-10
Press the LIGHT key to record the high
pressure. The LIGHT key LED will light
up and the ALARM key LED will turn off.
If the pressure from the external source
is less than or equal to the setting on low
pressure, the system will automatically
revert back to Step-2 and requires
calibration again.
Step-11
After the pressure calibration is
completed, only the STATIC key LED will
continue to light up on the panel. Press
the STATIC key to finish the pressure
calibration process.

15
2.2.7 Control Panel Testing SOP STEP-1
Check the panel surface for damage.
PIN definition: referring the left figure, it’s
the 1st ~13th PIN from top to end.
Step-2
Use a multi-meter and turn the dial to
symbol (Diode test).

16
Step 3
Touch the black probe contact to PIN 1 and the red probe
contact to PIN 2
The ALARM RESET LED will light up. This means the
ALARM RESET LED function is normal. Should there b
no light the panel is defective. e
anel
Step 4
Touch the black probe contact to PIN 5 and the red probe
contact to PIN 13.
The HEAVY LED will light up. This means the HEAVY
LED function is normal. Should there be no light the p
is defective.

17
Step 5
Touch the black probe contact to PIN 6 and the red probe
contact to PIN 13.
The MEDIUM LED will light up. This means the
MEDIUM LED function is normal. Should there be no
ight the panel is defectivel
The STATIC LED will light up. This means the STATIC
LED function is normal. Should there be no light the panel
is defective.
Step 6
Touch the black probe contact to PIN 7 and the red probe
contact to PIN 13
The LIGHT LED will light up. This means the LIGHT
LED function is normal. Should there be no light the
panel is defective
Step 7
Touch the black probe contact to PIN 8 and the red probe
contact to PIN 13

18
Step 8
Touch the black probe contact to PIN 9 and the red
probe contact to PIN 13.
Now Press the STATIC key. The multi-meter should
conduct.
Step 9
Touch the black probe contact to PIN 10 and the red probe
contact to PIN 13.
Now Press the LIGHT key. The multi-meter should now
conduct
Step 10
Touch the black probe contact to PIN 11 position and the
red probe contact to PIN 13
Now Press the MEDIUM key. The multi-meter should
conduct.
Step 11
Touch the black probe contact to PIN 12 and the red probe
contact to PIN 13.
Now Press the HEAVY key. The multi-meter should
conduct.

19
2.2.8 Transformer Function Test SOP
Step-1
Pass the required voltages through the high
voltage side of the transformer, and the
multi-meter test at the same side. This should
show the correct voltage within specification.
The transformer is functioning normally.
Step-2
Pass the required voltages through the high
voltage side to the transformer, and the
multi-meter test at the low voltage side. This
should show 10V AC±2V AC. The transformer
is functioning normally.
