TempMax?
Arguments:
No Arguments Taken
Example:
TempMax?
I2C Command Number:
Description
Returns the maximum temperature for channel CHANNEL. If the temperature is ever greater than MAXTEMP, the board will temporarily disable the temperature loop until the temperature drops below MAXTEMP. <html></div></html>
