TEACH-IN TEMPERATURE COMPENSATION (TEACH-IN)

This option enables the practical definition of the compensation curve over a specified
temperature range.
Steps for sucessful measurement.
Enter the temperature range (T
the difference between T - and T + exceeds 5°C.
During the measurement the temperature of the solution must reach
25°C.
Immerse the device into the solution and heat slowly from T- until T+ has
been reached (if T- < 25 °C < T+) or from 25°C until T+ has been reached
(if 25 °C < T- < T+) or from T- unitl 25°C has been reached
(if T- < T+ < 25 °C).
The compensation coefficients are automatically calculated and stored
for further reference within the "SPECIAL" option within the automatic
compensation option.
If the message "ERROR" appears on display, it means that a problem
has occured (for example the liquid has been heated too quickly). In this
case the operation must be repeated.
The increase in temperature must be slow in order to compensate the thermal
resistance of the temperature sensor.
Please avoid bubbles appearing on the surface of the sensor. The user can quit
the Teach-In option at any time by pressing for a duration of 5 sec.
