Actual temperature (°C / °F)
Provided that no operating mode has been selected, the actual temperature of the tem
-
perature sensor is displayed on the control station. The point above the first digit (Fig. 6)
indicates the operating status of the heating element. As long as this point is illuminated,
the heating element is being energized.
The fourth character of the LED display indicates the
selected temperature unit (°C / °F). If °F has been selected,
and the actual temperature rises above 999, then the
fourth character of the LED is used to display the tempera-
ture in full.
Standby mode
In the standby mode, a flashing actual temperature display indicates that the control sta
-
tion is regulating the solder bath according to the standby temperature of 200°C/390°F.
To disable this mode, press any key so that the tip temperature of the device will be
adjusted to the set value (see also item 5.3.3 on the stand-by feature).
No Tool
Fig. 7 shows what the display looks like when there is no
temperature sensor connected to the control station.
Insufficient temperature
The temperature measured by the temperature sensor lies
in the range of the cold junction temperature (approxi
-
mately the room temperature). The character string is
displayed (Fig. 8) until the temperature of the sensor has
risen sufficiently above the cold junction temperature.
