8.2 Measuring marking
Keep in mind that the measured part
of the object surface (3 point measuring
spot marking) changes with the in-
creasing measuring distance as shown
in the figure. The ratio between the
measuring distance and measuring
spot diameter isapproximately 60: 1 at
the focus point and approximately 35:1
in the distant field (> 10 m). To take continuous readings, set the LOCK switch in the
battery compartment to „On“ and press the measurement button (the laser does not
remain on continuously). Reset the LOCK switch to „Off“ for the normal operation.
The laser sight makes sighting a measurement object easier. Laser points indicate the
exact diameter of the measuring spot. You can use the LASER function key for switching
the laser on and off by keeping the measurement button pressed. The laser icon (refer
to 8.5 Display screen) indicates the switched-on laser.
8.3 Measurement
Aim at the object to be measured and press the measurement button. The measured
temperature is shown in the display. It is visible in the display for seven seconds after
releasing the measurement button. If another button is not pressed, the device switches
off automatically after this time. Selected functions remain set and the function selection
menu returns to the initial position. To recall the last measured value, press ENTER
without pressing the measurement button.
