Two types of temperature measurement are possible:
•
Measurement with infrared sensor (see chapter 4.1)
•
Measurement with thermocouple (see chapter 4.2)

Preparing for Measurement
Laser Warning!
When the instrument is switched on by means of the trigger,
the laser beam is immediately activated and the laser symbol
appears at the display.
Observe the safety precautions!
➭
Select a unit of measure: °C or °F (see chapter 7.1).
➭
Set emissivity in accordance with the table in the appendix de-
pending upon the type of object to be measured (see chapter 8.1).
➭
The field of view must be taken into consideration, i.e. distance
from the measuring point to the spot (see chapter 5.1).
➭
Aim the instrument at the object to be measured, holding it such
that you can easily read the LCD panel and pull the trigger with
your forefinger.
Make sure that the target is larger than the instrument’s measuring
spot. In the case of objects with large surfaces, make sure that you are
located within the permissible measuring range.
The laser dot can be used to take aim at the measuring point, and has
no measuring function of its own. The laser can be deactivated if
desired. Refer to chapter 7.1 regarding switch positions.
Single Measurements – HOLD Function
The instrument is switched and measurement is started when the
trigger is activated, which is acknowledged by means if a brief
acoustic signal. As soon as the trigger is released, the last measured
temperature is frozen at the main and auxiliary temperature displays
(as long as no special function has been selected), and
HOLD
appears
at the display simultaneously. After approximately 30 seconds, the
measuring instrument is switched off and the display goes blank.
