Hakko 852 SMD rework station, correct sensor resistance???
My hakko 852 SMD station does not work properly now.It refuse to blow
hot air. After i press the start button, the heater heat up and the air starts blowing(orange color from the heater). When the sensor detects the desired temperature, there will be no orange color from the heater and the air is still blowing. I tried to blow hot air to a piece of paper, but the paper did not even get burnt . I get correct resistance for the heater, but i got 1.2 ohm for the sensor. According to the manual, i should get 0 ohm for the sensor.(I think 0 ohm mean short) On my multimeter, short is 0.8ohm. So i am 0.4 ohm above the correct resistance. Does anyone has the Hakko 850 or 852 station? What's your sensor resistance? Thanks! |
