This display gives the overview of the gas/vapour concentrations last
measured – in this case the concentration of gas A and humidity of
the water vapour are in the units that were selected – that is mg/m 3
for gas A and Tdew for water vapour (see section 4.3.2 ).
4.3.7 Displaying Measurement Results while a Monitoring
Task is in Progress
If store measurement history is selected in the MEASUREMENT set-
up branch (see section 4.3.5 ) all measurement data collected during
a monitoring task is stored in Display Memory together with the
parameters which describe the task (see section 4.3.4 ).
Using the direction keys, you can scroll through this data.
1. After the monitoring task has been running for 10-15 minutes,
press q.
An example of the text which appears on the screen is shown below:
DATA IN DISPLAY MEMORY RECORDED
FROM
2014-01-16 09:50 TO 2014-01-16 10:04
This screen text allows you to find out how long the monitoring task
has been running here from 9:50 to 10:04 on the same day. The
date on the right-hand side of the display indicates the time at which
the last measurement cycle was completed while a monitoring task is
in progress this date is, of course, constantly updated.
2. Press q and then use t & u until the following text appears on
the display:
FILTER A USED TO MEASURE
(the name of the gas will appear here)
The displays which follow indicate the type of text which appears
each time q is pressed:
GAS A: MAX 14.5E+00 m 8.03+00
ALARM 1_____ MIN 7.42E+00 s 2.36E+00
While a monitoring task is being performed a running statistical
analysis of the monitored gases/vapours is made and the results are
displayed as shown above, where:
