Why is the measured tip temperature lower than the set temperature?
|Top page for "Why is the measured tip temperature lower than the set temperature?"|
|Check 1||Are the tip, element cover, nut, etc. oxidized?|
|Check 2||Is the tip shape changed?|
|Check 3||Has the sensor of the thermometer deteriorated? (In the case of HAKKO-manufactured contact-type measuring instruments)|
|Check 4||Are the batteries low on power?|
|Check 5||Is the correct measurement method suitable for the measuring instrument being performed?|
Check 3. Has the sensor of the thermometer deteriorated? (In the case of HAKKO-manufactured contact-type measuring instruments)
If the sensor is deteriorated due to corrosion by solder, the temperature may be shown lower in some cases. A sensor can last approx. 50 times in general; however, if lead-free solder is used, the sensor must be replaced more frequently.
*NOTE If a measuring instrument manufactured by another company is used, refer to its instruction manual.
Replace it with a new one before measuring the temperature. If the temperature is still shown lower, confirm the details in Checks 1, 2, 4 and 5.
