Instrument firmware version	Features added
1.1	Setpoint “press-and-hold” loads current temperature to setpoint
1.2	Capacitance option card support added. Minor bug fixes.
1.3	Thermocouple revision 2 is now supported. Minor bug fixes.
1.4	Fixed bug that causes the thermocouple option to read incorrectly when a diode is attached to input B. Changed ramp rate limit to allow rates as low as 0.001 K/min.
2.0	Fixed bug where a sensor overload on a control input may not shut off the heater if the input is configured as a PTC sensor. Fixed bug where resetting default values may not correctly reset all settings. Fixed bug where resetting to defaults corrupts the first reading of KEYST?
2.2	Input reading update rate corrected to be 10 readings a second, 5 readings a second on 100 kΩ range. Fixed bug that can cause one bad reading when changing ranges with current reversal on.
