1 PRECAUTIONS AND SAFETY MEASURES
The instrument has been designed in compliance with the directives relevant to electronic
measuring instruments. For your safety and to prevent damaging the instrument, please
carefully follow the procedures described in this manual and read all notes preceded by
symbol with the utmost attention. Before and after carrying out the measurements,
carefully observe the following instructions:
CAUTION
•Do not carry out any measurements in case gas, explosive materials or
flammables are present, or in humid or dusty environments
•Do not carry out any measurement in case you find anomalies in the
instrument such as deformation, breaks, substance leaks, absence of
display on the screen, etc
•Keep the instrument steady during any measuring operation
•Do not use the instrument in environments with temperatures
exceeding the operating and storage limits specified in § 8.1.1 in order
not to damage it
•Only the accessories provided together with the instrument will guarantee
safety standards. They must be used only if in good conditions and
replaced with identical models, when necessary
•Check that the battery is correctly inserted
•Check that the LCD display gives indications consistent with the function
selected
•Do not direct the instrument at very high intensity radiation sources
(e.g. the sun) in order to prevent damaging the IR sensor
•Prevent hits or strong vibrations to keep the instrument from damage
•When bringing the instrument from a cold to a hot environment, leave it on
long enough for condensation water to evaporate
In this manual, and on the instrument, the following symbol is used:
Warning: observe the instructions given in this manual; improper use could
damage the instrument or its components.
1.1 DURING USE
CAUTION
•Failure to comply with the caution notes and/or instructions may damage
the instrument or be a source of danger for the operator.
•Use the instrument only in the temperature ranges indicated in § 8.1.1.
1.2 AFTER USE
When measurement is complete, switch off the instrument. If you expect not to use the
instrument for a long period, remove the battery.

2 GENERAL DESCRIPTION
The instrument is a professional portable digital thermal camera capable of carrying out
infrared temperature measurements of objects and providing thermal images in an
extremely flexible way. It is also very easy to use and needs little maintenance.
The main characteristics of the instrument are:
•Temperature measurement ranging from -20°C to 550°C
•Built-in photo camera for a visible image
•PiP Fusion and Auto Fusion (AUF) function
•Cursor in a fixed central position
•Cursors for automatic detection of “hot” and “cold” spots of the image
•TFT color display with capacitive touchscreen
•8 color palettes available
•Electronic zoom x1-x32
•Advanced analyses (Spots, Lines, Areas, Isotherm lines)
•Automatic detection of hot/cold spots of the image
•“Screening” function for measurement of face temperature
•Storage of JPG images on external micro-SD card and in the internal memory
•IR sensor resolution: 120x90pxl
•USB-C port for PC connection and image and video transfer
•Built-in white LED illuminator
•Text annotation on saved images
•IR MP4 video recording on micro-SD card and in the internal memory
•Rechargeable Li-ION battery
•Analysis and creation of reports with the provided dedicated software
•WiFi interface to mobile devices through the APP HTProCamera
The applications of the digital thermal camera are:
•Predictive and preventive maintenance of electrical and mechanical appliances
•Monitoring of the temperature of working processes
•Maintenance and troubleshooting on forced ventilation ducts
•Domestic/industrial use in troubleshooting room insulation problems
•Applications in the construction field
•Safety problems

3 PREPARATION FOR USE
3.1 INITIAL CHECKS
Before shipping, the instrument has been checked from an electric as well as mechanical
point of view. All possible precautions have been taken so that it is delivered undamaged.
However, we recommend generally checking the instrument in order to detect possible
damage suffered during transport. In case anomalies are found, immediately contact the
forwarding agent. We also recommend checking that the packaging contains all
components indicated in § 7.5. In case of discrepancy, please contact the Dealer. In case
the instrument should be returned, please follow the instructions given in § 9.
3.2 INSTRUMENT POWER SUPPLY
The instrument is supplied by an integrated 1x3.7V, 1500mAh rechargeable Li-ION
battery. For battery recharge, please refer to § 7.2.
3.3 STORAGE
In order to guarantee precise measurement, after a long storage time under extreme
environmental conditions, wait for the instrument to come back to normal operating
conditions (see § 8.1.1).

4.2 DESCRIPTION OF FUNCTION KEYS
The instrument has 2 function keys described further with multiple functions.
4.2.1 Switching on the instrument
1. Press the key for 2s to switch on the instrument. After the initial splash screen is
displayed (see Fig. 6 –left side), the instrument needs for a certain heating time
(approx. 30s) to provide accurate temperature measurements and quality images.
2. The instrument initially shows the visible image for a few seconds and the message “IR
calibration…” while it correctly calibrates the internal sensor (see Fig. 6 –middle).
3. After a few seconds, the IR image is shown on the display and the instrument is ready
for measurement (see Fig. 6 –right side).
Fig. 6: Sequence upon switching on the instrument
CAUTION
•The sound that accompanies the message “IR Calibration…” is a
necessary condition for the instrument's internal calibration. The auto
calibration time can also be set and/or manually disabled (see § 5.2.1.2)
•Pressing the key allows switching on/off the instrument. The instrument
also has an Auto-Power-Off function with selectable time.
4.2.2 Switching off the instrument
1. Press the key for at least 4s to switch off the instrument. The following screen
appears on the display.
