Description/Abstract | A method of operating a calorimeter is called the servo controlled method.^An internal heater is driven by a controlled voltage source to produce a constant internal temperature.^The heater power is controlled by a digital computer program that uses as one of its inputs the bridge potential.^The heater power can be calculated by multiplying the heater current by the heater voltage.^A bridge potential can then be determined that will produce the desired internal power level.^When a sample is placed in the calorimeter the servo system reduces the heater power to maintain the set point bridge potential.^There will be four calorimeters in the system - two for large sizes and two for small sizes.^They will be servo controlled using a DEC Micro-11 computer with a IEEE-488 interface buss.^(LEW) |
