How does an induction cooktop measure temperature?
Induction cookers use NTC Thermistor temperature sensors, more specifically thermocouples to measure temperature.
But for 60 deg. C, I don’t think it can be much useful, because the thermocouple cannot measure such precise temperature (it measures only in 100s from 100–2000) like you said.
If you have a thermometer, insert it in the cooktop and make sure thermometer bulb is immersed in liquid to be boiled. Keep a close watch on the thermometer all the time. On and off the induction continuously to maintain 60 deg. C in the cooktop.
