Frequently Asked Questions
Is a charging option available for the gas detection instruments?
Yes. Gas detection instruments using rechargeable batteries can be charged,
if the Plus variant of the module was purchased. All Plus variants can charge
and apply gas!

 
It is recommended to connect mixed gases, including EX gases, to the first
valve, since the first valve is used first. This means the mixing adjustments are
carried out first, which usually already processes the majority of the sensors. In
addition, the process does not contain nitrogen, which reduces recovery times
in CAT EX sensors, since these have now been adjusted respectively tested.
MISCELLANEOUS Is there a recommended gassing order?
Yes. Some gases such as THT or EO are not or hardly available in concentrations
above the first alarm limit.
During the extended gas application test the Dräger X-dock checks for an accuracy
window. This can also be below the alarm limit – however, this is not arbitrary.
Dräger X-dock supports you here as well and rejects test gas concentrations that
are unsuitable. Nevertheless, e.g. a concentration of 10 ppm EO is accepted.
This also represents the first alarm limit and even if this is not exceeded while
the measured value is within the window, the test is regarded as passed.
Can I carry out a gas application test, if the applied calibration gas concentration
is below the alarm limit?
