Setting the emissivity
E
Short press (button 8): Value +0.1
Long press (button 8): Value runs through 0.1 ... 1.00
An integrated sensor head detects the material/surface-
specific infrared radiation emitted by all objects. The level
of these emissions is determined by the specific emissivity
of the material (0.1/10E to 1.00/100E). After switching
on for the first time, the device is preset to an emissivity
factor of 0.95, which is suitable for most organic materials
and non-metals (plastics, ceramics, wood, rubber, paints,
varnishes and stone). For materials with different emissivity
factors, refer to the table under Point 10.
Wherever possible, paint or matt black stickers can be
applied on non-coated metals and metal oxides, which due
to their low, temperature-unstable emissivity are suitable
for IR measurement only for a limited extent, as well as
on surfaces with unknown emissivity in order to set the
emissivity factor to 0.95. If this is not possible, use a contact
thermometer.
!
The emissivity last selected is set after the device
is switched on. Check the emissivity setting before
each measurement.

Probe sensor
To use the probe sensor for a measurement, fold out the
probe sensor and briefly press the „Probe" button (2). The
measurement takes 4 minutes. The device then switches off
automatically. The measured value is held (Hold) by pressing
the „Probe" button (2) again. Pressing the „Probe" button
(2) once more will restart the measurement. In Hold mode
the device switches off after 10 seconds.
It is possible to switch back to infrared measurement while
measuring with the probe sensor. By pressing and holding
the „Trigger" button (8) the value from the probe sensor is
held and marked with (Hold); infrared measurement starts.
By pressing the „Probe" button you switch back to measure-
ment with the probe sensor.

To measure the core temperature in frozen food,
drill a hole and then insert the measuring probe
into the product.
In accordance with regulation (EC) 1935/2004, the
!
fold-out probe sensor is designed for continuous
contact with food, from the measuring probe up
to approx. 10 mm before the plastic casing.
