4 Start-up
4.1 InTap4000e
Important! Before using the sensors for the first time, the electrolyte should be replaced (see «Section 5.8»).
Due to possible adverse conditions during transport and storage (e.g. airfreight, pressure and temperature
variations), the quality of the electrolyte may become impaired. Poor electrolyte quality can lead to erroneous
measurement values.
Note: Insert included batteries before start-up (refer to «Section 7.2» for detailed information).
Note: The sensor is delivered ex factory not connected to the transmitter. Therefore, it has to be polarized before
first time operation.
Connect the InTap sensor to the analyzer. After 6 hours, the sensor is fully polarized and ready for operation.
Leave the sensor permanently connected to the transmitter after first time polarization. This ensures that the
sensor is continuously supplied with a polarization voltage (even when the unit is switched off), thus avoiding
a polarization time of about 6 h before being ready to take a measurement. In addition, this protects the sensor
from contamination.
On the following page is the sequence for correct start-up and measurement application. Comply with
the described procedure in order to ensure optimal response time, a correct measurement result and
maximum hygiene.

1. Connect discharge tube (0.3 m) and bypass tube (0.3 m) to three-way valve (see picture below).
Warning! Push the tubes into the quick couplers to the stop.
Warning! The discharge tube may not be fitted with any form of extension, as this could allow air (avoid
measurement errors) to penetrate into the measuring chamber between measuring cycles.

2. Perform configuration of the measuring unit according to «Section 6.4»
This step is necessary during initial installation/start-up or if new requirements for configuration rise
have arisen.
3. Perform calibration according to «Section 6.5»
Calibration is essential during initial start-up of the instrument. In most instances, automatic calibration
in air is sufficient.
Note: We recommend periodic re-calibration. Frequency of re-calibration and the method used
(see «Section 6.5»), depend upon extent of use of the instrument, the required measurement accuracy
and you own experience.
4. Insert the sensor into the measuring chamber
After calibration, re-insert the sensor into the measuring chamber and tighten the sleeve nut.

Add one conditioning tablet.
Let stand for 5 minutes (do not
stir or shake) until the tablet has
completely dissolved.
Draw off 25 ml of cleaning and
conditioning solution using the
syringe (pull plunger up to the
stop). Make sure to remove any
air bubbles.
6. Fill the measuring chamber with cleaning and conditioning solution
Connect the syringe with tube
connection (diam. 6 mm) to
the measuring chamber.
Turn the three-way valve to
«Measuring position», then inject
approx. 15 ml of cleaning and
conditioning solution into measur-
ing chamber.

Let cleaning and conditioning solution act:
Minimum time of exposure to the cleaning and conditioning solution: 15 minutes
Maximum time of exposure to the cleaning and conditioning solution: 1 week
Note: If no measurements are carried out with the InTap within three days, the cleaning and conditioning
solution should be removed from the measuring chamber, and both the sensor and the measuring chamber
thoroughly dried.
Turn the sampling valve to the
«BYPASS» position, then remove
syringe with tubing connection.

7. Connecting the feed tube
8. Process connection
As the beverage industry does not have any valid worldwide standard for connections to storage tanks or
pipes, no special tube adapter for connection to processes is included in the scope of our supply. Connec-
tion of the feed tube to the process is the responsibility of the customer.
For the Perlick-type connections used on storage tanks in the USA, METTLER TOLEDO offers either the
InTap4004e or an appropriate tank sample adapter port (order no. 52 200 261) as an optional accessory.
Warning! Leaky tube couplings between process and measuring chamber (sensor) are the most
frequent cause of erroneous measurements. All tube couplings and tube extensions between the
process connection and the measuring chamber must therefore be absolutely leakproof.
Warning! Special care has been taken in the selection of a material with low oxygen permeability for
the feed tube connected to the process. Therefore, only use the feed tube supplied by us.
Warning!
Push feed tube into the quick coupler to the stop.
