3. WARNINGS, CAUTIONS AND NOTES

In this manual, items requiring caution are classied into 2 categories, "WARNINGS" and
"CAUTIONS", as dened below. Please make sure to understand these items before reading

the main text.

WARNING :

CAUTION : Failure to comply with a CAUTION may result in injury to the operator, or damage

NOTE : Indicates important steps or items in the procedure being explained.

Be sure to observe the following warning items.

󱾀The unit is for a counter or workbench use only.

󱾀This appliance can be used by children aged from 8 years and above and persons with reduced

physical, sensory or mental capabilities or lack of experience and knowledge if they have been

given supervision or instruction concerning use of the appliance in safe way and understand the

hazards involved.

󱾀Children shall not play with the appliance.

󱾀Cleaning and user maintenance shall not be made by children without supervision.

Be sure to observe the following warning items, for which failure to do so may cause
accidents or malfunctions.

󱾀This unit is for indoor use only.

󱾀When using the thermometer to measure the temperature of the soldering iron tip or desoldering

nozzle, pay great attention to the temperature of the tip or nozzle since it will be as high as 200 to

450°C (392 to 842°F). Careless handling of such a hot object may result in a burn or re.

󱾀Do not modify this product.

󱾀Do not get this product wet or use it with wet hands.

󱾀Be sure to unplug the power plug before internal inspection or replacement of parts. Failure to do so

may cause an electric shock.

󱾀Use HAKKO genuine parts as replacement parts.

󱾀When inserting or unplugging the power plug, do so while holding the plug, not the cord.

󱾀Do not perform dangerous actions.

Failure to comply with a WARNING may result in serious injury or death.

type receptacle.

2) The power receptacle of the HAKKO

FG-101B main body supplies power

only when the power switch is turned

on.

CAUTION



Since the sensor is made of ultra-

thin (Ø0.2) K thermocouple, pressing
the sensor strongly may cause it to be

disconnected. Handle it with care.

4-2 Measurement of tip

temperature

1) Press the SELECT button to set the

mode to "TEMP".

New solder

2) Apply a new coat of solder on

the tip and touch it on the sensor

measurement part (See the gures at

right.)

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.

CAUTION

• Since the main body is partially
made of resin, be careful not to
touch the tip to the main body. In
addition, also be careful not to

touch the tip to the terminal or the

slide pin.

• Although the measurement point

of the sensor undergoes special
treatment, it will deteriorate
gradually due to repeated
measurements. In order to measure

the temperature correctly, if the

measurement point is worn out,
replace the sensor with a new

one. The reference number for

sensor replacement is approx. 50

measurements.

Do not measure the temperature by applying

hot air (HAKKO FR-811, etc.) directly to the
HAKKO FG-101B. If hot air is applied directly,
the HAKKO FG-101B will be damaged.

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.

1) Plug the power plug of the soldering

iron to be measured into the power

receptacle the HAKKO FG-101B

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

5) Clean the tip and apply a new coat of

solder on the tip.

button.

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.

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.

4-4 Measurement of resistance di󰀨erence between tip and ground wire

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 "OHM".

AUTO ZERO function

AUTO ZERO function is necessary for measureing voltage (mV) and resistance (OHM).

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.

5. MAINTENANCE

Maintenance and Calibration

• To replace the conduction plate, remove the set screws.

• The life of the temperature sensor will vary depending on the temperature at which

measurements are made and the type of solder and ux being used. In general, temperature

sensors can be used for 50 measurements. Replace the sensor as soon as the measuring

point wears out.

• HAKKO can calibrate the instrument for a nominal fee. Please contact your dealer for further

information.

CAUTION

Pressing the POWER button while holding the button pressed changes the
temperature unit between ˚C and ˚F.
