Process Test; Oxidation Phase Process Test; Pressure Test - Hach BioTector B7000 User Manual

Process Test

This menu allows the user to simulate the:
i) Oxidation Phase Process Tests, which are Pressure Test, Flow Test, Ozone Test, Sample Pump Test
and pH Test routines.
ii) Liquid Phase Process Tests, which are Purge TN Cell Test, Clean TN Cell Test, Read DI Water
Reference Test and Read TN Sample Test.

This menu enables the user to simulate the Pressure Test. The menu also shows the current status of the
Mass Flow Controller. Any settings made by the user in this menu are automatically reset when the user exits
this menu.
1. Pressure Test. Use this function to simulate the Pressure Test. When the Pressure Test is activated, an
"*" will be shown, and a small menu will display the following data:
Time:
MFC Setpoint:
MFC Flow:
Status:
2. Pressurize Reactor. This is similar to the Pressure Test above, but its time has been extended to 999s,
allowing the user to locate any leak there may be on the system. Pass, Warning and Fail are
automatically shown on the screen, depending on the status of the test.
3. TIC Pressure Test. In TC - TIC systems only, use this function to simulate the Pressure Test, which
includes TIC reactor. In TC - TIC systems, Pressure Test function above includes the TC reactor in the
test.
4. Pressurize TIC Reactor. In TC - TIC systems only, use this function to pressurize the TIC reactor. In TC
- TIC systems, Pressurize Reactor function above pressurizes the TC reactor in the test.

The time for the pressure test is 60 seconds. This time shows the time left to the end
of the test.
This is the BioTector mass flow controller setting for the pressure test.
This is the actual flow from the mass flow controller. Initially the setpoint and flow will
match, and if there is no gas leak, after about 25 seconds the flow will fall to close to
zero.
At the end of the test, the status below is shown:
TESTING: Test in progress.
PASS: The Pressure Test finished its cycle with a flow below the Pass
(Pressure Test Warning) level.
WARNING: The Pressure Test finished its cycle with a flow above the Pass
(Pressure Test Warning) level, but below the Fail (Pressure Test
Fault) level.
FAIL: The Pressure Test finished its cycle with a flow above the Fail
(Pressure Test Fault) level.
