7.1 Measuring the Temperature
1. Aim the IR sensor at the target and press the measurement trigger to
display the target's surface temperature. A red laser spot appears on
the target during measurement.
2. The distance-to-target ratio is 13:1. This means that, for example, at
13 cm, the target must be larger than 1 cm to get a proper
measurement. Make sure the target area is within this field of view.
3. The device can measure temperatures in °C or °F. Press the up/down
key while the device is on to switch between measurement units. The
corresponding symbol (°C or °F) appears on the display.
