“t” or “t[i]” Returns the current temperature reading for channel # i.
Ex: “t4 E“ will return the temperature for channel # 4. “t E”, with the HHTFO101 thermometer, will return:
+24.3<CR>
*
The “t” command is also available in a special “ta” version, that can be useful for continuously and automatically monitoring all enabled channels. This special mode is recommended when automatically acquiring temperature readings with a suitable
“C:I;T: ±xxx.x<CR>”
where i is the channel number, and xxx.x is the temperature reading (signed number).
“u[i]” Set units of measurements to either Celsius (i=c) or Fahrenheit (i=f). Note that this unit selection is the same as the temperature unit selection made from the keypad (if the display option is installed).
Ex: | “uc E“, to select ºC (Celsius). |
“y” The “y” command can be used to confirm the “signal strength” of a probe and/or its connection. It can be used as a diagnostic tool to confirm the good operation of a probe and its patch cord (if applicable) connected to a channel. The returned value can be between 0.3 to approximately 3.00; a higher value is better. A minimum of 1.25 is required for a channel to return a temperature.
Ex: “y E”, with the HHTFO101 thermometer, will return:
CH1: power:2.61, lamp attenuation: 250, CCD time: 50ms (fixed)<CR>
*: 0.3 to 1.1 indicates that no probe is detected for this channel.
