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.

Operation

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 switched 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 determined by material and intended method of working. Please always perform a test at a point that is hidden from view.

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.
• The measurement results obtained for reflective objects may be corrupted.
• 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.
• Prolonged use at high temperatures may cause the HG Scan PRO to heat up and deliver results that diverge from the actual surface temperature.

Settings

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

Airflow setting| 4| 5| 6| 5
Emissivity| 0.95| 0.85| 0.9| 0.94

d) LOC function
To avoid altering the chosen settings unintentionally, the HG Scan PRO comes with the Lockable Override Control Function (LOC).
To find out how to set the LOC function, please contact our Service Department on +44/1733/366-700.

Alarm function

HG Scan PRO comes with an alarm function that is activated when the temperature measured exceeds or falls below the temperature selected. The alarm is given in acoustic form by an audio signal and in visual form by a blue and red LED ring. The alarm is triggered when the temperature measured exceeds or falls below the temperature that is set.
A green LED ring shows that the temperature measured by HG Scan PRO is equivalent to the target value within the tolerance. The acoustic audio signal can be deactivated. To deactivate the audio signal, go to the section on “Settings”.
