Operation with pump

With Dräger Pump X-am 1/2/5000
Accessories:
Dräger Pump X-am 1/2/5000, sampling hose and probes, refer to Order List, see
"Accessories" on page 57..
Commissioning and performing the measurement:
•
Refer to the Instructions for Use of the Dräger Pump X-am 1/2/5000.

With manual pump adapter and rubber ball pump

Accessories:
For manual pump adapter, rubber ball pump, sampling hose and probes, refer to Order
List, see "Accessories" on page 57..
Commissioning and performing the measurement:
•
Refer to the Instructions for Use of the accessories used.

Observe the following during measuring mode with pump

•
The required waiting time when flushing the hose probe:
Before every measurement, flush the Dräger sampling hose or the Dräger probes
with the air sample to be measured.
−
It is absolutely necessary to flush the extension hose to eliminate or minimize the
effects which may interfere with measurements when using a sampling hose or a
probe, e.g., memory effects, dead volume.
−
The flushing phase depends on various factors, e.g., type and concentration of the
gas or vapor to be measured, material, length, diameter, and age of the sampling
hose or probe. Generally, when using a sampling hose (new, dry, clean), a typical
flushing time of approx. 3 seconds is required for each meter. This flushing time ap-
plies in addition to the sensor response time (see the Instructions for Use of the gas
measuring device used).
Example:
−
In the case of a sampling hose with a length of 10 m, the flushing time is approx.
30 seconds and the sensor response time is in addition approx. 60 seconds. There-
fore, the total time before reading the gas measuring device is approx. 90 seconds.
−
The flow rate alarm is delayed by 10 to 30 seconds depending on the length of the
hose.
