1314i Photoacoustic Gas Monitor

LumaSense Technologies A/S

Page 47 of 199

The displays which follow indicate the type of text which appears

each time q is pressed:

GAS A: MAX 84.5E+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:

MAX = maximum concentration of gas A measured during the

period of time the monitoring task has been performed.

MIN = minimum concentration of gas A measured during the

period of time the monitoring task has been performed.

ALARM 1= the user-defined concentration of gas A which, if

measured by the Monitor, will trigger a switch in the

Monitor and activate an external alarm relay connected to

it.

m

= linear average, or mean value, of all the gas A

concentrations measured during the period of time the

monitoring task has been performed

s

= standard deviation of gas A’s concentrations from the

mean value (m) described above (see

section 8.1

for

further details).

All numbers are written in the exponential form, for example:

84.5E+00 = 84.5 x 10

+0

= 84.5

The concentration unit in this case is mg/m3 as this was chosen in

the active set-up (see

section 4.3.2

).

3. Press q.

A:

(the name of the gas being measure by Filter A will appear here)

972.06 mBar

2014-01-16 09:50:32 ___________ 7.42 mg/m3

A:

(the name of the gas being measure by Filter A will appear here)

972.06 mBar

2014-01-16 09:51:33 ___________ 7.42 mg/m3

As you can see, the display provides the date and time at which the

measurement was made, and the concentration of gas A is given in

the units mg/m

3

because this was the unit chosen for gas

concentration in the active set-up. The dashed lines, which appear

after the time will be replaced by a number as soon as the

monitoring task has been stopped (see

section 4.3.8

).
