EMISSIVITY ADJUSTMENT (-MA and -CB MODELS) The emissivity setting on OS-MINI with MA output models may be adjusted via two rotary switches inside the electronics box. To adjust the emissivity setting: Set the left switch to the first digit after the decimal point (0.1). Set the right switch to the second digit after the decimal point (0.01). - Page 10 OS-MINIUSB SPECIFICATIONS The OS-MINIUSB is a simple, compact infrared temperature sensor with USB communications. It measures the surface temperature of a variety of materials without contact. The included software is intuitive and easy to use, and the open Modbus protocol allows users to connect directly to the sensor using software of their own design.

Page 24: Installation
Preparation Mechanical Installation Electrical Installation Please read the following sections thoroughly before proceeding with the installation. OS-MINI SERIES PREPARATION Ensure that the sensor is positioned so that it is focused on the target only. OS-MINI22 and OS-MINIUSB OS-MINI DISTANCE AND SPOT SIZE The size of the area (spot size) to be measured determines the distance between the sensor and the target. - Page 25 The OS-MINI and OS-MINI22 are tested to industrial standards for electromagnetic compatibility (EMC) as shown in Specifications at the beginning of this manual. To minimize electromagnetic interference or ‘noise’, the OS-MINI series sensor should be mounted away from motors, generators and such like.
