Volume Display
Volume up to 99.999 m³ can be displayed in litres by setting the volume display to
Auto
. The
alternative is a display in m³ at all times.
Auto Restart
The supervisor can select what happens if power is interrupted. The test can stop at that point or
resume when power is restored and complete as programmed. The supervisor can select the number
of restarts allowed in a particular test (up to 50) and the maximum duration of a power failure (up to
100 hours).
Real time & date
These parameters will rarely need to be accessed, unless for example, GMT changes to BST or
vice
versa
.
Test mode
Five operating modes are available, and once a mode is selected it will be the test that will run
whenever the operator selects
Run test
.
1. Timed test
This will start as soon as the operator confirms that a test is to be run. It will continue until the
selected test duration (e.g. 10 minutes) has elapsed.
2. Volume test
This will start as soon as the operator confirms that a test is to be run. It will continue until the
selected volume of air (e.g. 600 litres) has been sampled.
3. Delayed timed test
This mode will be entered as soon as the operator selects
Run test
. The start time and test duration
will be displayed until the operator selects
confirm
. The display will then change to Real time and
start time. Sampling will not commence until the preset start time, and will continue for the preset
duration unless a low flow alarm condition occurs.
4. Delayed volume test
This mode will be entered as soon as the operator selects
Run test
. The start time and volume to be
sampled will be displayed until the operator selects
confirm
. The display will then change to Real
time and start time.
Sampling will not commence until the preset start time, and will continue until the selected volume
of air has been sampled, unless a low flow alarm condition occurs.
5. Open ended test
This mode will be entered as soon as the operator selects
Run test
and then
confirm
to start the
test.
The test will run until
stop
is selected by the operator. Flow, total volume and elapsed time will be
displayed during the test.
