Continuous Sampling 19
4 Continuous Sampling
The LPA² can be selected for continuous testing at set time intervals.
Once continuous sampling has started the LPA²’s flush valve auto-
matically opens and closes before each test. This allows representa-
tive fluid to reach the sensing arrangement before the 15ml sampling
test commences.
The flush valve automatically opens at the end of the sampling cycle
and remains open whilst the LPA² is emptying to waste the sample
fluid from the previous test. Additionally, depending on the time set
for Minutes Between Tests, the flush valve operates as follows:-
• Time set to 0:
At the end of the Analyser’s emptying cycle the Flush valve au-
tomatically closes and the next sampling test immediately starts.
• Time set to between 1 and 5:
After the Analyser’s emptying cycle has finished the Flush valve
remains open for the time set, then automatically closes before
the next sampling test.
• Time set to between 6 and 30000:
Flush valve automatically closes after the emptying cycle has
finished and remains closed until 5 minutes before the next sam-
ple test is programmed to start.
The Flush valve status is indicated by the push button illumination.
Not illuminated means valve closed, illuminated means valve open.
The servo motor operating the Flush valve exhibits a slight ‘ticking’
noise, both when it is open and closed. This is normal.
