Attaching / detaching (Fig. / Fig. )
1. Fit HGScanPRO onto hot air tool b and d.
2. The HGScanPRO is switched ON by
pressing the ON/OFF button (4). While the
HG Scan PRO is activated, the display on
the hot air tool shows the operating symbol
(5). The HG Scan PRO can be used after
switching ON at the controls of the hot
air tool. The HG Scan PRO has a memory
function. If it was active during the last time
of use, it will be reactivated automatically
the next time the HG 2620 is switched ON.
Otherwise, it remains inactive until it is swit-
ched ON by pressing ON/OFF (4).
3. When switching ON for the first time, the
device is active in the state it was in on
leaving the factory:
temperature setting = 150 °C / 300 °F,
airflow setting 5,
alarm tolerance level = 10 °C / 50 °F,
emissivity = 0.90,
audio signal ON.
4. The temperature and airflow rate are deter-
mined by material and intended method of
working. Please always perform a test at a
point that is hidden from view.
Operation
b
Attaching to / detaching from HG 2620 E
(Fig. 2)
1. Switch OFF HG 2620 E and disconnect from
the power supply.
2. Undo screws on side of guard sleeve and
remove guard sleeve. Now remove
cover cap.
3. Fit guard sleeve into HGScanPRO.
4. Fit guard sleeve with HGScanPRO onto the
HG 2620 E and tighten screws at side.
5. HG 2620 E ready for use with
HGScanPRO. Keep the cover cap in a safe
place in case HGScanPRO is removed
again.
Attaching to / detaching from HG 2520 E
(Fig. 4)
1. Switch OFF HG 2520 E and disconnect from
the power supply.
2. Undo screws on front of guard sleeve and
remove guard sleeve. Now remove
cover cap.
3. Fit HGScanPRO onto HG 2520 E
4. Now fit guard sleeve back on and tighten
front screws.
5. HG 2520 E ready for use with
HGScanPRO. Keep the cover cap in a safe
place in case HGScanPRO is removed
again.
n The ideal measurement area is 10 cm in
front of the hot air tool's delivery outlet and
measures approx. 2 cm (at the point where
both laser beams intersect). Reducing /
increasing the distance will cause results to
vary.
n To obtain accurate results, the object being
measured must be larger than the measure-
ment area. It is recommended for the object
being measured to be at least twice the size
of the measurement area.
n HGScanPRO is unable to take measure-
ments through transparent surfaces, such as
glass. Instead, HGScanPRO measures the
surface temperature of the glass.
n Nozzles that deflect air and/or cut off sens-
ing because of their length cannot be used
with the HGScanPRO.
n The measurement results obtained for
reflective objects may be corrupted.
n To obtain accurate results, HGScanPRO
must be allowed to reach ambient tem-
perature. This also applies when moving
from one place of use to another.
n Prolonged use at high temperatures may
cause the HG Scan PRO to heat up and
deliver results that diverge from the actual
surface temperature.

a) Settings
The following settings can be made:
directly:
• Temperature
through the settings menu:
• Airflow: 150-600 l/min
• Alarm tolerance level: 10/20 °C, 50/70 °F
• Emissivity: 0.10-0.99
• Audio ON/OFF
The temperature setting is selected directly by
using the joystick. Move the joystick to the right
to increase the temperature setting or to the left
to reduce it.
The airflow button takes you to HGScanPRO's
Settings menu where you can make further
settings. Programmes can be selected at the
programme button. For further details, please
read the section on "Programme mode".
1. Set the airflow by pressing the airflow but-
ton. The airflow symbol (10) on the display
flashes while airflow is being set. Move the
joystick to the right to increase the tem-
perature setting or to the left to reduce it.
If you do not wish to change the setting,
please continue at 2.
2. Emissivity is set by pressing the airflow but-
ton a second time. The display shows the
letter "E" (8) while emissivity is being set.
Move the joystick to the right to increase
emissivity or to the left to reduce it. For
further information on this, please read the
section on Emissivity. If you do not wish to
change the setting, please continue at 3.
3. Set the alarm tolerance level by pressing
the airflow button a second time. The
display shows the letter "L" (7) while the
alarm tolerance level is being set. Move the
joystick to the right to increase the alarm
tolerance level or to the left to reduce it. For
further information on this, please read the
section on "Alarm function". If you do not
wish to change the setting, please continue
at 4.
4. Set the audio signal by pressing the airflow
button a second time. The letter "A" (7) ap-
pears on the display while the audio signal
is being set. Move the joystick to the right
to switch the audio signal ON and to the
left to switch it OFF. If you do not wish to
change the setting, please continue at 5.
5. Press the airflow button a second time to
leave the Settings menu.
HGScanPRO starts to measure the tem-
perature straight away.
b) Programme mode
Four programmes are factory-set for the
most common types of work. After pressing
the programme button, number 1 (7) is
displayed for programme 1. Continuing to
press the programme button displays num-
bers 2-4 (7) for programmes 2–4. Pressing
the button again will return the tool to nor-
mal operation. No number (7) is displayed in
normal mode.
c) Memory function
The values selected for the four programmes
can be changed and memorised at any time.
To do this, first press the programme button
until the display shows the programme you
wish to change. Select the chosen temperature
setting, airflow and emissivity. The memory
symbol on the display flashes to indicate that
the programme selected has been changed.
To memorise this setting in the programme
selected, press and hold down the programme
button. The memory symbol continues to flash
for approx. 2 sec. The settings entered are
saved once the memory symbol stays on all the
time. The alarm tolerance level and audio signal
can be changed in normal mode and applied to
all programmes.
