1. Description
When using digital soldering stations, the calibration box WCB1 and WCB2 are used as the
external input unit for programming the following additional functions.
● Offset: Correction value for soldering tip temperature
● Setback: Reduction of the set temperature after a specified period of time.
● Lock: Locking the set temperature
● °C/°F: Switching temperature display °C/°F
● Window: Setting a set value window. If the actual temperature is within the set value
window, a potential-free contact is activated.
● Cal: WCB 1: Reset to factory setting (FSE)
WCB 2: New calibration of soldering station and reset to factory setting
(FSE)
PC interface (RS232) and integrated temperature gauge for thermoelement Type K are part
of the extended functional scope of the calibration box WCB2.
2. Start-up
Remove the soldering iron from the power supply unit. Insert the calibration box cable (5)
into the soldering iron bushing. Pressing the ON/OFF button (to switch calibration box ON/
OFF) puts the calibration box into ready mode (blinking cursor in display (1)).
These functions, shown on the keys, are activated in connection with the shift key (to be
pressed at the same time as the function key).
The following entries are possible:
● Offset:
The actual soldering tip temperature can be changed by ± 40°C (± 72°F) by entering
temperature correction value (offset)
The current offset value is displayed after selecting the offset function (Shift-Offset).
It is then possible to enter a new value and to confirm it by pressing the offset key (Shift-
Offset) again (negative entries are possible with the ± key). The setting is confirmed in the
display with „ON"; if „0" was entered, this is confirmed with „OFF".
GB
If no confirmation takes place, the display will switch back to the ready mode (blinking
cursor) after a short period of time, and the old value is retained.
Example: Set temperature = 350 °C, measured soldering tip temperature = 352 °C. This
results in an offset of -2 °C (± key). New soldering tip temperature = 350 °C.
● Setback:
Reduction of the set temperature to 150 °C (standby). After the soldering station switches
to the standby mode, the setback time can be adjusted from 0 to 99 minutes.
After pressing the setback key the current setback time will be displayed. It is now
possible to enter a new value (0 - 99) and to confirm this value by pressing the setback
key again. The setting is confirmed in the display with „ON", and with „OFF" if „0" was
set (setback function is deactivated). If no confirmation takes place, the display switches
back to the ready mode (blinker cursor) after a short period of time, and the old value is
retained.
If the soldering tip temperature does not fall more than 5 °C below the set temperature
within the setback time, or if no finger-tip operating pressure is applied (i.e. soldering
tool is not used) the set temperature is reduced to a temperature which is less damaging
to the soldering tip (150 °C). This operating mode is signalled by a blinking actual value
display. The set temperature value is restored by pressing any key on the power supply
unit or applying finger-tip pressure.
● Lock:
Locking the set temperature. After locking has taken place, no other changes to the setting
of the power supply unit can be made.
After selecting the lock function the current set temperature will be displayed. It is now
possible to enter a new value and to lock this value by pressing the lock key again. This
setting is confirmed in the display with „ON". The lock is cancelled by pressing the lock
key twice (without entering a temperature). This setting is confirmed in the display with
„OFF".
