Performing fine adjustments for temperature
When different tips are used during soldering, the change in tip shape and its respective thermal capacity causes the actual temperature to deviate from the preset temperature.
If the original tip is 900M-T-B with a set temperature of 350ºC, changing to:
- 900M-T-I will cause the displayed temperature to be approximately 10ºC lower
- 900M-T-K will cause the displayed temperature to be approximately 30ºC higher
To determine whether there is a need for calibration adjustments, first measure the tip temperature with the FG-100B Thermometer.
- If the temperature reading on the thermometer accurately reflects the set temperature on the soldering iron/station, no calibration is needed.
- If the temperature reading on the thermometer differs from the set temperature on the soldering iron/station, calibration is required.
As such, to maintain the same tip temperature, it is necessary to perform fine adjustment (calibration or offset value adjustments).
Calibration Adjustment for FX-600/FX-601
Insert a tool such as a screwdriver and adjust the CAL volume*. Turning anticlockwise decreases the temperature and turning clockwise increases the temperature.
* Since the CAL position varies depending on each product, refer to their instruction manual.
Calibration Adjustment for Soldering Station
*The example shown here is for the FX-888D. For other models, please refer to the instruction manual.
- Press and hold the 'UP' button on the FX-888D until "ADJ" shows on the display.
- Enter the value as shown on the thermometer, and press 'ENTER'.
- Allow a couple of seconds for the station to calibrate.
- Test the temperature of the tip with the thermometer - it should now accurately reflect the temperature that is set on the station.
