PREFACE

Manual Objectives: This manual shows you how to set up and use the RTD Panel Thermometer.

This meter is an economical Miniature Temperature Panel Thermometer featuring a large display with a linearized analog output that is supplied as a standard feature.

Each of the models* can be converted by the user to display in degrees Fahrenheit or Celsius between one degree and a tenth degree resolution.

RTD is an abbreviation for resistive temperature detector. The meter is designed to measure 100 ohm platinum resistance with 0.00385 temperature coefficient, also known as the European curve. The RTD will change resistance with a change in temperature. When using a 2-wire measurement configuration, lead wire impedance can contribute significant error to the temperature measurement. When using long lead wires a 3- or 4-wire measurement configuration is recommended.

The meter is available in platinum RTD with 2-, 3-, or 4-wire connections. All of the models listed in Table 1-1come standard with red LEDs, and can be ordered with a green LED display as an option. The part numbers would then end with Ò-GR".

Also, these meters can be ordered with different power configurations. Refer to Table 1-3for available choices.

*Refer to Table 1-1for the complete listing of models available.
