How to measure the tip to ground resistance

How to measure the tip to ground resistance

1. Insert the power plug of soldering iron to be tested into the receptacle on the flank of HAKKO FG-101.
Insert the power plug of the soldering iron to be tested here.

2. Wait until the temperature of the soldering tip reaches the setting.

3. Press the SELECT button to change the mode display to "OHM".
When the soldering tip does not contact the sensor, the display shows "burnout indication".


4. Press the AUTO ZERO button and wait until the display returns to normal status.
The correction value generated by the AUTO ZERO function is recoreded in the main unit. It remains in the memory even when the power is turned OFF, and is valid also in the next measurement.

5. Clean the soldering tip and put fresh solder on it.

6. Place a tiny bead of solder in the center of conduction plate and heat the bead until suitable wettability is obtained.
Note Place solder in the center of the conduction plate to ensure contact between the soldering tip and the conduction plate.
