Omega 24 User Manual

GENERAL INFORMATION
This manual provides operating instructions and maintenance information for
five temperature instruments. These instruments are high performance cali-
brator-thermometers capable of simulating and measuring a wide-variety of
sensors. In addition, features such as data storage and ramping further
enhance their versatility.
It is recommended that you read this manual thoroughly, especially the sec-
tions on safety, prior to operating these instruments.
