•
Do not use any accessories or wearing parts to TTI-22 other than those supplied or approved by
Isothermal Technology Ltd.
•
Make sure all operators are trained to use the instrument safely and correctly before starting any
applicable operations.
•
In case of damage or malfunction, do not continue operating TTI-22. Do not operate the instrument
under conditions which could result in damage to goods and/or injuries and loss of life.
•
Check if the wetted parts are chemically resistant to the samples and rinsing agents.
2.1.3 Maintenance and Service
•
The results delivered by TTI-22 not only depend on the correct function of the instrument, but also
on various other factors. We therefore recommend to have the results checked (e.g. plausibility
tested) by skilled personnel before consequential actions are taken based on the results.
•
Service and repair procedures may only be carried out by authorized personnel or by Isothermal
Technology Ltd.
2.1.4 Disposal
•
Concerning the disposal of TTI-22 observe the legal requirements in your country.
2.2
Special Safety Instructions
•
Only use shielded cables for connecting the sensors.
•
Only connect separated extra low voltage circuits (SELV according to EN60950) to the instrument.
•
Keep an appropriate term for repeating the calibration of the used reference resistor and/or sensor.
Recalibrate TTI-22 and sensors at least once a year.
•
The following cases require you to perform an instrument self-check (turn off the instrument for at
least 3-4 seconds) and control the set parameters (RRef, Sensor Calibration, User Password):
-
before large measuring cycles
-
after extraordinary operating conditions
-
after service work on the instrument
•
Avoid exposing TTI-22 to direct sunlight and major temperature changes. After large ambient
temperature changes, TTI-22 requires some time to adjust to the ambient conditions.
