Why is the measured tip temperature lower than the set temperature?
Check 2. Is the tip shape changed?
Since the length and weight vary depending on the tip type, if the tip shape is changed, the thermal capacity will be changed, causing the temperature to become lower or higher in some cases.
When using the 900M-T-B tip with the set temperature of 350ºC, if the tip is changed to the 900M-T-I or 900M-T-K tip
If changing to the 900M-T-I, the displayed temperature is approx. 10ºC lower.
If changing to the 900M-T-K, the displayed temperature is approx. 30ºC higher.
Therefore, to maintain the same temperature, it is necessary to perform fine adjustment (calibration adjustment or change of offset value) without fail.
Perform temperature fine adjustment (calibration adjustment or change of offset value) before remeasurement. If the temperature is still shown lower, confirm the details in Checks 1 and 3 through 5.
Insert a tool such as a screwdriver and adjust the CAL volume.Turning anticlockwise decreases the temperature and turning clockwise increases the temperature.
[Position of CAL volume]
* Since the CAL position varies depending on each product, refer to their instruction manual.
[Changing the offset value]
Change the offset value while referring to each instruction manual.
It shows how to offset, for example HAKKO FX-951.
