Point 2-a: For HAKKO FX-301 | Point 2-b: For HAKKO FX-300
Point 2-a. Method for setting correct temperature (offset value)
<For HAKKO FX-301>

HAKKO FX-301 is equipped with a digital indicator of pot temperature to enable correct temperature control.

Temperature measurement method
Connect the temperature probe (No. A1310) for solder pot to the HAKKO FG-101/HAKKO FG-100 and insert the end into the center of the solder in the pot to measure the temperature.

Offset value setting method
The temperature indicated on the FX-301 and the measured temperature are sometimes different depending on the work environment. In this case, change the offset value.

Point 2-b. Method for setting correct temperature
<For HAKKO FX-300>
HAKKO FX-300 is an analog-type soldering pot in which temperature is adjusted by turning a knob.

Knob temperature indication
The knob temperature indication is a reference temperature. Note that actual temperature may vary depending on individual product differences and usage methods.
