Frequently Asked Questions - Scanner termic HG Scan HG 2620 E STEINEL

How to install the HG Scan PRO on the hot air gun?

Turn off and unplug the gun. Remove the protective nozzle, mount the protective sleeve on the HG Scan PRO, then snap the whole assembly onto the gun. Tighten the side screws (HG 2620 E) or front screws (HG 2520 E). Keep the nozzle for future removal.

How to turn on the HG Scan PRO?

Press the ON/OFF button (4). The operating symbol (5) appears on the gun's display. If the device was activated during the last use, it automatically restarts with the HG 2620 model.

What is the recommended measurement distance?

Place the device 10 cm from the object, resulting in a measurement spot of about 2 cm (intersection of the two laser beams). The object must be at least twice as large as the measurement spot for accurate results.

How to adjust the emissivity?

Press the air flow button several times until the letter 'E' appears on the display. Turn the dial to adjust from 0.10 to 0.99. The default emissivity is 0.90. Refer to the table in the manual for values according to material.

What do the colors of the LED ring mean?

Green: temperature within tolerance. Red: temperature above setpoint + tolerance. Blue: temperature below setpoint - tolerance. Audible signals accompany exceedances of more than 20 °C (or 40 °F).

How to modify preset programs?

Press the program button to select the program (1-4). Adjust the temperature, air flow, and emissivity. The memory symbol flashes: hold the program button until the symbol stays on. The tolerance and audible signal are common to all programs.

Is the laser dangerous?

The laser is class 2 (< 1 mW). Do not look directly into the beam and do not point at eyes. Do not use with optical instruments.

How to clean the lens of the HG Scan PRO?

Use a soft, lint-free cloth slightly damp (no detergent). You can also use a lens cleaning liquid. Avoid acidic products, alcohol, or solvents.

Can nozzles be used with the HG Scan PRO?

No, nozzles that deflect air or are too long interfere with the measurement. Use only the original propulsion tube.

What to do if the measurement seems inaccurate?

Check the distance (10 cm), the emissivity suitable for the material, the cleanliness of the lens, and the ambient temperature. The HG Scan PRO must be acclimatized if it comes from a different environment. Avoid shiny or transparent surfaces (glass) for surface measurement.

Operating instructions

Designed for use with Steinel hot air tools, HG Scan PRO is a temperature scanner that uses infrared for measuring temperature on a contactless basis. During use, HG Scan PRO gives you an acoustic and visual warning if the temperature measured exceeds or falls below the temperature selected. It is powered from

the hot air tool. Please familiarise yourself with these operating instructions before using this product.

Prolonged reliable and trouble-free operation will only be ensured through correct handling.

Safety warnings

Tampering or technical modifications will result in the loss of warranty cover and exemption from liability.
Do not expose the device to any major mechanical strain or strong vibration.
The device must not be exposed to high levels of air humidity nor must it be allowed to get wet. Outdoors, the device must only be used in appropriate weather conditions or provided with appropriate protection.
Smoke, dust, steam and/or other vapours may adversely affect the HG Scan PRO's optical system and lead to incorrect results being displayed.

Switch the device OFF and prevent it from being switched ON unintentionally if it must be assumed that safe operation cannot be ensured. e.g. if

• the device shows visible damage
• the device does not work or
• the device has be exposed to adverse conditions for a prolonged period
• the product has been exposed to severe strain in transit.
• disconnect the HG 2520/2620 from the mains power supply before attaching / detaching.

Safety warnings

This device may be used by children aged 8 or above and by persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they are supervised or have been given instructions on how to use the tool safely and understand the hazards involved.

LASER RADIATION DO NOT LOOK INTO BEAM = 630 nm - 670 nm LASER CLASS 2 < 1 mW EN 60825-1:2008-05

How it works

HG Scan PRO measures an object's surface temperature. The heat radiated from the object is measured by the scanner's sensor and transmitted to the hot air tool. Emissivity is a value used to describe the relative ability of a material to emit thermal energy by radiation (characteristic "radiance").

The greater the emissivity, the more capable the material is of emitting thermal energy. Most organic materials and surfaces have a emissivity coefficient of approx. 0.90. Metallic surfaces or shiny materials have a lower emissivity coefficient. HG Scan PRO's emissivity can be selected so as to rule out imprecise measured values.

Attaching / detaching (Fig. ② / Fig. ④)

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.

Operation

1. Fit HG Scan PRO onto hot air tool ② and ④.
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 switched ON by pressing ON/OFF (4).

Measuring temperature (Fig. ⑤)

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.
To obtain accurate results, the object being measured must be larger than the measurement area. It is recommended for the object being measured to be at least twice the size of the measurement area.
■ HG Scan PRO is unable to take measurements through transparent surfaces, such as glass. Instead, HG Scan PRO measures the surface temperature of the glass.
Nozzles that deflect air and/or cut off sensing because of their length cannot be used with the HG Scan PRO.

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.

6. 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.

7. The temperature and airflow rate are determined by material and intended method of working. Please always perform a test at a point that is hidden from view.

■ The measurement results obtained for reflective objects may be corrupted.
To obtain accurate results, HG Scan PRO must be allowed to reach ambient temperature. This also applies when moving from one place of use to another.
■ Prolonged use at high temperatures may cause the HG Scan PRO to heat up and deliver results that diverge from the actual surface temperature.
