ALPHA

This probe parameter refers to the average sensitivity of the probe between 0
and 100°C. The value of this parameter is set at the factory for best instrument
accuracy.

DELTA

This probe parameter characterizes the curvature of the resistance-temperature
relationship of the sensor. The value of this parameter is set at the factory for
best instrument accuracy.

Operating Parameters

Baud Rate

The baud rate is the first parameter in the menu. The baud rate setting deter-
mines the serial communications transmission rate.
The baud rate parameter is indicated by,
