General Specifications

Output: 4-20 mA
Supply Voltage: 24 V DC (13 V to 28 V DC)
Display Format: 3.5 digit LCD
Display Units: Emissivity (0.2 to 1.0) or current (4 to 20 mA)
Adjustment: Push-buttons (raise/lower/set)

Connecting the PyroEpsilon to the PyroTune:

1. Connect only the power wires PWR+ and PWR- of the sensor to a 24 V DC powered 4-20 mA measurement loop. Connect the emissivity input wires IP+ and IP- to each other, and do not connect them to the power supply.

2. Obtain a temperature reading without emissivity adjustment.

3. Connect IP+ and IP- to the 4-20 mA output terminals of the PyroTune.

4. Connect a power supply to the input terminals of the PyroTune and switch on the power.

5. Use the push button controls to change the emissivity setting until the sensor reads correctly.

There are several ways to find the correct emissivity setting
