With the C2 Communications Windows based software, temperature probes are driven to the preselected Setpoint temperatures (COOL and HEAT), the Measure reads the probe outputs, the probe error is calculated, and the process is repeated at the next temperature, all without operator intervention. Calibration and Validation data can be recalled at the next calibration interval.

C1      RS-485 Output Only. The Models 20 and 34 are equipped with a 9 pin D            connector to facilitate the user's programming.
