6.1 Packaging
Keep the product packaging for the duration of the warranty period for
reference should the product need to be returned for repair.
WARNING! Keep packaging materials out of reach of children. Dispose
of packaging correctly and responsibly and in accordance with local
regulations.
7. Operation
Important: Read and understand all the safety instructions listed in this
manual before using this product.
Install a 9V PP3 battery (supplied) before use; see
8.2 Replacing the
Battery.
DO NOT use this product in environments with abnormally high or low
ambient temperatures as this may deliver inaccurate readings. If the
product has been stored for an extended period in a location with an
elevated or starkly different temperature, allow it to rest at an ambient
temperature of 20~50°C for approximately 30 minutes before use.
WARNING! This product is not suitable for use on humans or animals.
7.1 Distance and Spot Size
1
Fig.
This product operates by measuring the overall temperature of a specific
area of the target surface (the “spot”). The diameter of the spot (“spot
size”) equates to roughly one-twelfth of the distance from the
thermometer to the target surface. As the distance
D increases, the spot
size
S also increases.
For more precise measurements of specific areas, position the
thermometer closer to the surface. For more general measurements,
position the thermometer further from the target surface.
Important: The target surface must ALWAYS be larger than the spot size.
For greater accuracy, ensure that the target surface is at least twice the
size of the spot area.
The product is equipped with a laser pointer that can be enabled to guide
your aim.
7.2 Emissivity
This device is configured to calculate temperature assuming an emissivity
value of 0.95, a general value suitable for most organic materials and
painted or oxidised surfaces. Because of this, readings from reflective or
polished surfaces may be inaccurate. To improve accuracy, cover an area
of the target surface measuring twice the spot size (see
7.1 Distance and
Spot Size) in masking tape or black paint. Allow it to reach the same
temperature as the material underneath before taking a measurement.
Important: DO NOT place glass, Perspex or other transparent materials
between the thermometer and the target surface when attempting to take
a measurement.

The LCD display activates when the trigger is depressed. Symbols are
displayed when the corresponding setting is enabled. To toggle each
setting, press the appropriate button. Press again to return to the original
state.
When enabled, the laser beam is only active while the thermometer is
switched on and the trigger is depressed.
The scanning active symbol (15) is displayed while the trigger is
depressed and indicates that the device is reading temperature in
real-time. The last measurement symbol (16) is displayed when the
trigger is released and indicates that the temperature reading shown is
the last recorded value.
The thermometer and LCD display switch off automatically after
approximately 15 seconds of inactivity.
7.4 Taking a Measurement
WARNING! DO NOT direct the laser beam towards yourself, another
person or animals.
1. Squeeze the trigger to switch on the device.
2. Configure the control panel as required; see
7.3 The Control Panel.
3. Aim the thermometer at the target surface, taking the distance and
spot size into consideration; see
7.1 Distance and Spot Size.
− The laser can be used to guide your aim, if activated.
4. Holding the thermometer steady, squeeze the trigger; the temperature
reading is shown on the LCD display.
Important: The thermometer continues to record the temperature of the
target surface until the trigger is released and updates in real-time if the
temperature of the target changes while the trigger is depressed. The
scanning active symbol (15) is displayed while the thermometer is
measuring the temperature.
