Checking The Operating Hours Meter; Checking The O 2 Concentration - Weinmann OXYMAT 3 Servicing And Repair Instructions

5.3.8 Checking the operating hours meter

Check that the red minute counter on the operating
hours meter is incremented every 6 minutes.

5.3.9 Checking the O
Leave the OXYMAT 3 to run for at least 10 minutes
before starting the measurement.
Before you check the oxygen concentration on the
OXYMAT 3, you must first calibrate the oxygen
measuring device (e.g. OXYcontrol WM 13550).
For this purpose, you will need the respiratory tube
WM 5726 and an oxygen cylinder with an ad-
justable pressure reducer (e.g. WM 33100).
Caution !
Please observe the instructions for handling oxygen!
Important!
Before calibrating the oxygen sensor for the first
time, the sensor must be stored in ambient air for
at least 15 minutes (refer to instructions for use of
the sensor).
The oxygen measuring device is now calibrated
and you can check the oxygen concentration on
OXYMAT 3.
Please remember that OXYMAT 3 must have already
been operational for at least 10 minutes.
When operating with a dosage monitor:
Important!
It is vital that you empty the humidifier glass 25 of the
bubble humidifier; otherwise, the oxygen sensor of
the oxygen measuring device will be damaged.
7. Connect the oxygen measuring device:

How to calibrate the oxygen sensor:
1. Connect the oxygen measuring device to the
pressure reducer of the oxygen cylinder using
the respiratory tube WM 5726.
2. open the cylinder valve. One revolution

is sufficient!
3. Set a flow of 4 l/min at the pressure reducer.
4. Leave the oxygen measuring device (e.g.
OXYcontrol) flowing for approximately 2 minutes,
until the displayed oxygen level remains steady
5. Set a value of "100" using the calibration
knob.
6. Close the cylinder valve again.
