The display flashes briefly.
The timer is programmed and active.
The decimal point flashes on the display until the setpoint temperature is
reached. The timer starts once the setpoint temperature has been reached. The
actual temperature and remaining operating time are now displayed in turns.
After the set time has elapsed, a double acoustic signal sounds and the device
switches to standby mode.
The setpoint temperature can still be changed until it is reached. The timer
remains active and starts when the new setpoint temperature is reached. If the
setpoint temperature is changed while the timer is running, the timer is
deactivated.
The running timer is stopped with the
[OK]
key.
8.9 Adjusting the temperature sensor (ATC)
For physical reasons, there can be a temperature difference in the bath tank
between the temperature sensor and a defined, more remote point within the
bath fluid volume. As a result, the measured temperature deviates slightly from
the actual bath temperature. Adjustment of the temperature sensor can increase
accuracy of the temperature control application.
The adjustment of a temperature sensor requires the determination of the
temperature difference between the temperature sensor and the reference
thermometer. Three adjustment options are available:
• 1-point adjustment: When a sample is tempered to a certain setpoint. The
adjustment curve is displaced parallel to the original curve by the reference
amount.
• 2-point adjustment: When the temperature is controlled between two
setpoints. The slope of the temperature curve is adjusted between two
points.
• 3-point adjustment: When temperature is controlled within a temperature
range. This results in an arched temperature curve.
