■
Check for a broken heater or sensor
Verify the electrical integrity of the heater and sensor.
Measure the resistance of the heater and sensor while at room temperature (15℃ to 25℃; 59 to 77℉)
It should be 3.

Ω±10
%
. If the resistance exceeds these limits, replace it.
■
Check the grounding line
1. Unplug the iron cable from the station.
2. Measure the resistance between the pin 2 and tip with the iron cable connected to
the HAKKO FX-8002.
3. If the value exceeds 2Ω (at room temperature), perform the tip maintenance in page 16.
If the value still does not decrease, check the connection cord for breakage.
■
Check the iron cable for breakage
Measure the resistance of the pin.
Pin 1 to Pin 3
-
3.0 to 3.8Ω
If the resistance exceeds these limits, replace the iron cable.
Contact your HAKKO representative.
■
Replace the fuse
1. Unplug the power cord from the power receptacle.
2. Remove the fuse holder.
3. Replace the fuse.
4. Put the fuse holder back in place.
Unless otherwise directed, carry out these procedures with power switch OFF and the power UNPLUGGED.
