Continuous Sampling - Danfoss Vickers Target-Pro 2 Operation Manual

Continuous
Sampling
C o n t i n u o u s S a m p l i n g — S e t I n t e r v a l s
The analyzer can run continuous tests at set time intervals.
Once continuous sampling has started, the flush valve
opens and closes automatically before each test. This lets
fluid reach the sensing arrangement before the 15ml sam-
pling test begins.
The flush valve automatically opens at the end of the sam-
pling cycle and remains open while the analyzer is emptying
the sample fluid from the previous test.
Depending on the time set for minutes between tests, the
flush valve operates as follows:
Time set to 0:
At the end of the emptying cycle, the flush valve automati-
cally closes and the next sampling test beginsimmediately.
Time set between 1 and 5:
After the emptying cycle ends, the flush valve remains open
for the time set, then closes automatically before the next
sampling test.
Time set between 6 and 30000:
Flush valve automatically closes after the emptying cycle
ends, and remains closed until 5 minutes before the next
sample test is programmed to begin.
Notes:
When the flush valve pushbutton is lighted, the valve is
open; when the pushbutton light is off, the valve is closed.
The flush valve servo motor makes a slight 'ticking'
noise, whether the valve is open or closed. This is normal.
Do not connect the waste fluid hose to a pressurized sys-
tem; this will cause the analyzer to malfunction and could
cause internal leakage. Discharge the waste fluid hose into
the bottle provided, or into a tank or vessel vented to the
atmosphere.
To conserve battery life, connect the analyzer to the power
adapter for continuous operation.

2. Test Options—Press [6], then press the rele-
vant key to switch between option selections:
1. Set minutes between tests: Press [1], enter the time in
minutes required between tests (value must be between 1
and 30000), and press [Return].
2. Set ISO Target Level: Press [2], enter 0 (zero), and press
[Return].
3. Set NAS Target Level: Press [3], enter 0 (zero), and press
[Return].
4. Set logging: Press [4] once to log every test, repeat; press
[4] again to deselect logging.
Note: If you deselect log every test, the analyzer will not store
any test results in its memory.
3. Press the ush valve pushbutton to open the valve; the
pushbutton will light up. Leave the valve open for at least 1
minute or 200ml of fluid—more if the HP sampling hose is
longer than 1.5m.
4. Press the ush valve pushbutton to close the valve; the
pushbutton light will go o .
Alternate method: Proceed to step 5—pressing
the start button [1] automatically closes the flush
valve before sampling begins.
5. Press the start button [1].The analyzer will
begin the sampling cycle.
6. The completion progress bar indicates test status:
Results will be displayed automatically on the screen; if
auto print mode is on, results will be automatically printed
at the end of the sampling cycle; if auto print is off, press
the print key for a copy of the printed results.
7. Between tests, status will show Waiting.
8. Press the stop button [2] at any point in the cycle to end
continuous sampling. Test status will show Idle.
