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.

Remove the End Cap to get to the Emissivity Single Turn Pot (Fig. 3-2). Set the Emissivity Pot based on the target surface. Then put back the End Cap.

Make sure the output load is within the product specification.
