point
Tip
NOTE:
When measuring, apply a new coat of solder on the tip. This action is required to ensure
that the conductive plate comes in rm contact with the tip.

6
NOTE :
If solder can't wet easily on the conductive plate due to low tip temperature or because of
the tip having small thermal capacity, use the included conductive wire.
Replacement method
Remove the 2 screws attaching the conductive plate, replace the conductive plate with the
conductive wire, and then attach the conductive wire with the removed screws.
4. OPERATION(continued)
NOTE :
During measurement of leak voltage, even
when the tip is not applied to the conductive
plate, values are displayed; however, this is
not a malfunction of the product. In addition,
when values out of measurement range are
detected, burnout will be displayed, and this is
also not a malfunction.
1) Plug the power plug of the soldering
iron to be measured into the power
receptacle the HAKKO FG-101B
main body.
2) Wait until the tip reaches the
set temperature. If the soldering
iron temperature is variable, set
temperature to maximum.
3) Press the SELECT button and
change the mode to "mV".
4) Press the button.
Refer to " AUTO ZERO function"
(page 8) in "4-5 Explanation about
various functions".
5) Clean the tip and apply a new coat of
solder on the tip.
6) Apply a coating of solder to the center
of the conductive plate and heat it
until a good soldering wet condition is
achieved.
7) When the display temperature is
stable, read the values.
4-3 Measurement of leak voltage
CAUTION
• Before measuring the voltage or resistance, be sure to connect the main body
power cord to a two-pole grounded-type receptacle.
• If values exceeding specied ones are displayed as results for voltage or
resistance, check the tip and attaching screws of the soldering iron for looseness
and take another measurement.

Pressing the button displays "counting": 0.0.0 →0.0 →0.
Wait until the normal display appears.
Correction values from AUTO ZERO are recorded in the main body. Even after the power is
turned o󰀨, the correction values are still available in later measurement sessions.
Before using this function, it is necessary to cancel the "AUTO HOLD" displays.
AUTO HOLD function
When the button is pressed quickly (less than one second), "AUTO" will blink at the lower
right of the LCD.
While "AUTO" is blinking, touch the soldering iron tip to the sensor. (temperature)
While "AUTO" is blinking, touch the soldering iron tip to the conductive plate. (mV, OHM)
"AUTO" will stop blinking and stay lit after a certain amount of time, and the xed
measurement result will be displayed.
Even after the xed result is displayed, applying the tip to the sensor or the conductive plate
will enable the AUTO HOLD function to work again.
Each time the button is pressed, the AUTO HOLD function toggles between ON and OFF.
The AUTO HOLD function does not assume the measurement by temperature probes such
as the hot air.
Data send function (infrared)
Press the button for longer than one second.
Temperature data will be sent by infrared output
from the upper part of the HAKKO FG-101B. The
temperature display will blink during sending.
The temperature send function can send data only
