Performing the measurement
4.2.1
Dräger accuro
NOTICE
Perform measurement and evaluation in accordance with the Instruc-
tions for Use of the used Dräger-Tube and the Instructions for Use of
the Dräger accuro.
When using extension hoses up to a length of 3 m the Dräger-Tube
can be read without any need for a correction factor.
Using a 10 m and 15 m extension hose:
Single-stroke measurement
1. Suck the sampling air through the tube with one pump stroke. As
soon as the white indicator mark at the Dräger accuro becomes
visible, the pump stroke is finished.
2. Wait for two minutes before removing the tube from the sampling
point. Evaluation is effected in accordance with the Instructions for
Use of the used Dräger-Tube. Correction of the measurement re-
sult is not required for the single-stroke measurement.
Several-stroke measurement
1. Suck the sampling air through the Dräger-Tube with the specified
number of strokes. Refer to the corresponding Instructions for Use
of the used Dräger-Tube.
2. Always perform the next stroke once the white indicator mark at
the Dräger accuro becomes visible. No waiting period is required
after the final stroke.
If several-stroke measurement is performed with the 10 m or 15 m ex-
tension hose, the reading for some Dräger-Tubes has to be multiplied
by a correction factor (see table on page 13).
