1 General Information About the Drager Service Mode SW 2.xx
You can operate the DragerService Mode with the Info key and the Reset key. These keys
allow you to change the set values, to scroll through tests, or to confirm execution of a
specific test. The DragerService Mode is subdivided into the Customer Service Mode (CSM)
and the Extended Service Mode (ESM). The working language used throughout the
DragerService Mode is English.
The DragerService Mode in Oxylog 2000 has 17 tests:
• The first five tests (Test 001 through Test 005) are specifically designed for the
customer (CSM), but can also be used by Drager service technicians.
• The other twelve tests (Test 011 through Test 022) are part of the Extended Service
Mode (ESM) which is used to carry out calibrations. These tests are only accessible to
Drager service technicians. To do so, the Drager service technician must enter a
numeric code.
1.1 Definition of the Original Status
Each function in the DragerService Mode can be carried out separately. At the beginning of
the DragerService Mode and after completion of a specific test, the Oxylog 2000 enters one
of the following original status.

1.2 Calibration Functions
The following table lists the four calibration functions available in the DragerService Mode.
The data is stored in the EEPROM:

Test No.
1 adjusting the language CSM/ESM 001
2 calibrating the pressure sensors (P-Vers, P-
AIRMIX, P_LA)
ESM 011
3 calibrating the minute volume valve ESM 012, 013
4 calibrating the autozero offset ESM 017
Caution:
After installing a new Control PCB, carefully follow the steps for calibrating (nos. 1 through
4) specified in the table above.
After installing a new Sensor PCB, perform Test Oil “Calibrating the Pressure Sensors P-
Supply and P-LA".
1.3 Reaction in the Event of a Technical Error (TE)
If Oxylog 2000 detects a technical error, it will show the error number on the display. The
technical error and the name of the current test are displayed alternately at 2-second
intervals. In the event of a technical error, all tests can be carried out normally. The message
on the display disappears as soon as the technical error has been corrected.
A new Control PCB will generate the error No. 16 (invalid check sum in the EEPROM) before
initial calibration. This technical error will disappear as soon as all data has been calibrated.

3.2 Test 012: Calibrating the Minute Volume Valve in No Air Mix
During the calibration sequence (Test 012), you will be prompted to perform specific steps.
The displayed flow value (Norn.) is the calibration point. At the beginning of calibration, the
most recent stored flow value is adjusted. You can change this value by pressing the Reset
key or the Info key. You cannot stop the calibration process, once it has started.
At each calibration point, you must adjust the flow by pressing the Info key or the Reset key
so that the value shown on the display matches those given in the steps for calibration.
Test Setup
adjust cal. points
• Adjust the mode switch to IPPV.
• Adjust the mode selector switch AirMix/NoAirMix to No Air Mix position.
• Set the selector switch PEEP/CPAP to 0 mbar.
• Select the Extended Service Mode (ESM).
• Press the Reset key or the Info key to select Test 012.
• Press the Info key and the Reset key simultaneously to activate Test 012.
