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.
