Page 6: How It Works
How it Works Infrared thermometers measure the surface tempera- ture of an object. The unit’s optics sense emitted, reflected, and transmitted energy, which is collected and focused onto a detector. The unit’s electronics translate the information into a temperature reading which is displayed on the unit. - Page 7 Emissivity Emissivity is a term used to describe the energy- emitting characteristics of materials. Most (90% of typical applications) organic materials and painted or oxidized surfaces have an emissivity of 0.95 (preset in the unit). Inaccurate readings will result from measuring shiny or polished metal surfaces. To compensate, cover the surface to be measured with black tape or flat black paint.

Page 9: Setup And Operation
Setup and Operation 1. Hold the meter by its handle grip and point it toward the surface to be measured. 2. Pull and hold the trigger to turn the meter on and begin testing. The display will light if the battery is good. - Page 10 Setup and Operation (continued) b. Trigger Lock. Use for continuous monitoring of temperatures. When the Lock icon is flashing, use the Up or Down button to turn “on”. Then press the MODE button again to enter setting. Once you press the measurement trigger, the Lock icon is shown, confirming the lock measurement mode.

- Page 14 Maintenance, Recalibration, and Repair (continued) It is recommended that Digi-Sense products are calibrated annually to ensure proper function and accurate measure- ments; however, your quality system or regulatory body may require more frequent calibrations. To schedule your recalibration, please contact InnoCal, an ISO 17025 calibra- tion laboratory accredited by A2LA.
