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.
