7.7.4 GT, GTF Go To Temperature
This command instructs the controller to control to the setpoint specified in the
command. Bit 4 (setpoint reached) of the Status Byte is set when the chamber or
platform has stabilized within .1 degree of the setpoint for 15 seconds. The
command syntax is:
GT<space>[-]ttt.t<CR><LF> Celsius mode
GTF<space>[-]ttt.t<CR><LF> Fahrenheit mode
Example:
GT 125<CR><LF> Celsius mode
GTF 180<CR><LF> Fahrenheit mode
7.7.5 RA, RAF Ramp to Temperature
This command executes a ramping function. The operands of the command
include a ramp temperature and a ramp time. The controller will execute a linear
ramp from the current temperature to the specified temperature over the specified
time period. Bit 4 (setpoint reached) of the Status Byte is set when the chamber
or platform has stabilized within .1 degree of the setpoint for 15 seconds. The
command syntax is:
RA<space>[-]ttt.t<space>hh<space>mm<CR><LF> Celsius mode
RAF<space>[-]ttt.t<space>hh<space>mm<CR><LF> Fahrenheit mode
Where ttt.t is the final setpoint temperature
hh are hours to be used for the ramp
mm are the minutes to be used for the ramp
Example:
RA -55 2 15<CR><LF> Celsius mode
RAF -55 2 15<CR><LF> Fahrenheit mode
Ramps to -55
/ over 2 hours and 15 minutes
