T 4 Temperature, Continuous, °F
The T4 command requests continuous temperature readings in degrees Fahrenheit.
RS-232 reading rate is controlled by the IC command setting. The reading resolution is
0.1 degrees F. (Default - see T1 command)
Inquiry: *ddT4
Type: $*ddIN or *ddIN
Type: $*99IN or *99IN
Note: For RS-485 units, when the continuous transmit parameter is NOT active (is not set to
TO=C), the T4 command sends only one reading.
Note: For RS-232 units, type a $*99IN to stop this command. The '$' character suspends the tem-
perature readings while the
