4.3.2 Temperature Measurement
• Point the IR Sensor to the area or object to measure, and press
the "ON/HOLD".
• While the "ON/HOLD" button is kept pressed, the LT800 is
continuously measuring the temperature of the object pointed
at, with the IR Sensor.
• When the "ON/HOLD" button is released the instrument will hold
the last temperature reading for 6 seconds, and then shut off
automatically.
4.3.3 Selecting Temperature Units (°C/°F).
• Make sure the the instrument is turn ON, if not press the "ON/
OFF" button.
• Pressing the "°C/°F" button, will alternate the measuring units,
