9.1 Quick Start

To use the OSP infrared thermometer right away follow this simple steps :
Point the instrument at the object you want to measure and pull the trigger (the actual temperature value, the pre-
programmed emissivity value and the auxiliary indication will be displayed); a “LOCK” symbol will appear on display.
Set emissivity value using the <> and <> keys. Refer to appendix A to define emissivity and for emissivity tables.
Press and release the trigger to switch the unit off.

9.2 How to Operate the instrument

To switch the instrument “On” keep the trigger pressed; when the trigger is released the instrument will be switched “Off”.
When continuous operations are required press twice, in sequence, the trigger to lock the operative mode.
The first display indication will show the type of instrument and the temperature technical unit enabled.
