Introduction 1 SECTION 1 - INTRODUCTION The model OS136 series is a very low-cost, super-compact infrared transmitter. It measures temperature via non-contact, and provides an analog output proportional to the measured temperature. The OS136 series is offered in two temperature ranges: -18 to 204ºC (0 to 400ºF) and 149 to 538ºC (300 to 1000ºF). The analog output is offered as 4 to 20 mA, 0 to 5 Vdc, 0 to 10 Vdc, 10 mV/Degree C or F, or K type thermocouple. The unit has a fixed Emissivity of 0.95

Operation 3 SECTION 3 – OPERATION 3.1 – Measuring Temperature Before starting to measure temperature, make sure the following check list is met: The Power and output connections are made (Fig 2-1) The target is larger than the optical field of view of the transmitter (Fig 3-1) Use the Laser Sighting accessory (Optional), to align the transmitter to the center of the target area. The Emissivity is fixed at 0.95. No adjustment is necessary. If the target Emissivity is less than 0.95, you c
