Preface - Omega DP116-RTD User Manual

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 1-1 come
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".
Example: DP116-MF1-GR
Also, these meters can be ordered with different power
configurations. Refer to Table 1-3 for available choices.
*Refer to Table 1-1 for the complete listing of models available.
