Dräger X-act 5000
1 Measurement with Dräger short-term
tubes in technical gases
Addendum to chapter 3.2.2 of the Instructions for Use
CAUTION
!
The Dräger Short-Term Tubes are calibrated for
measurements in air. For measurements in technical
gases using the Dräger short-term tubes, only the
menu "MEASUREMENT TECHN. GAS" shall be used.
Otherwise it will result in considerable measurement
errors.
NOTICE
i i
The "MEASUREMENT TECHN. GAS" mode is desig-
ned to consider the different viscosity of a technical
gas compared to the viscosity of ambient air. Prior to
this measurement, the user must adjust the volume
flow needed for the measurement in technical gases.
Perform the adjustment and measurement as follows:
1. Connect the resistance tube (6527562) to the tube socket
(gas-inlet) of the Dräger X-act 5000.
2. Connect the resistance tube to the technical gas using an
extension hose of max. 1 m (3 ft) length.
3. Follow the instructions on the display.
4. Remove the resistance tube after adjustment.
5. Connect the extension hose to the tube socket (gas-inlet)
of the Dräger X-act 5000.
6. Connect the Dräger-Tube to be used both to the extension
hose (max. 1 m (3 ft)) and the technical gas.
7. Follow the instructions on the display.
For measurements in technical gases, the standard deviation
(refer to the instructions for use of the used Dräger-Tube) can
be increased by additionally approx. 10 to 15 %.
The following Dräger-Tubes can be used for measurements in
the technical gases listed below.

Addendum to chapter 3.2.3 of the Instructions for Use
Additionally, it is possible to adjust the set flow rate for sample
taking if needed.
1. Connect the opened sample tube or system to the tube
socket (gas-inlet) of the Dräger X-act 5000.
2. Connect a flow meter to the sample tube or system.
3. Follow the instructions on the display.
4. When the "SET OK & START" prompt occurs on the
display, press the green "OK" key to start the
measurement.
5. Compare the flow rate shown on the display with the flow
rate indicated on the external flow meter. If needed, adjust
the flow rate using the blue "UP" and "DOWN" keys.
The effects of the adjustment last only for the duration of the
present sample taking measurement.
However, if the present sample taking measurement is
interrupted because the depleted battery must be replaced,
this set flow rate will be saved and restored along with the
carbon dioxide
other sample taking data that is already saved and restored
until the battery is replaced and the present sample taking
carbon dioxide
measurement is finished.
