6.2 How to read the measurement value of the built-in temperature sensors.

MDT652S has two built-in temperature sensors.
The controller can monitor inside temperatures by using those sensors through RS-232C.
The following shows the procedure for reading the temperatures from the sensors.
Step 1. Select a temperature sensor which you want to read.
