Functional description
5.3.2
Temperature unit feature (
�
)
This feature serves to set the desired temperature unit (°C or °F) via the (+) and (-) keys.
Note:
If the station is protected by a password, then the parameters can be
changed only by entering the correct password (see 5.3.7 Password
Feature).
5.3.3
Standby feature (
�
)
This feature switches the control station to a state of readiness if it has not been used
over a preset period of time. The purpose of this feature is for example to reduce oxide
formation and energy consumption.
In standby, the temperature is lowered to 200 °C (390 °F). The standby time is set in
increments of hours. The setting range is 0 – 24 hours, with an input of 0 disabling the
standby feature.
When the station enters standby mode, the display starts to flash. Pressing an arbitrary
key returns the station to the originally set normal mode.
The station can also be manually changed to “standby” by changing the program, if, for
example, you wish to drop down to a particular temperature.
5.3.4
Tip Offset feature (
�
)
With Tip Offset, the temperature sensor determines the
type of thermocouple in the form of a number
