①Turn the POWER ON, and set the MODE to Ω or mV. Connect the dedicated ground cord to the unit, then touch one end to the plate and record the measurement (V₁ or R₁) (See Fig.1).
②Using the dedicated adapter, connect the 3-wire type soldering iron, then turn the power ON and set to the maximum temperature (see Fig.2).
③Connect the dedicated ground cord and the dedicated adapter.
After the temperature stabilizes, touch the tip in the center of the plate, then record that value (V₂ or R₂).
Use the recorded values and the formula below to make the calculation.
Leakage voltage V= V₂ - V₁, or Ground resistance R = R₂ - R₁
