Follow the calibration instructions for your particular kit. Make certain that there is a good attachment of the silicon seal to the existing cable. The Heathkit part number of the module was typically a or a Sealing the assembled temperature sensor in the tube. An active shunt regulator is connected across the power.
Assembled and Tested Temperature Sensor. I L e Low temperature output current A. Ground Referred Centigrade Thermometer. The circuit was taken directly from the National LM datasheet. Y Internal op amp with frequency compensation.
Y Uncalibrated accuracy g 10 C. Temp Sensor board attached to old cable end. This will take a couple of hours. The remaining 6 inches can be used to re-attach the old probe, should you feel it necessary for trouble shooting or whatever reason.
The 0 01 in the above and following equations is in units of V K or V C. V z e Shunt regulator voltage. This should create a water-tight seal. Letting it stand overnight is best. Meter Thermometer With Trimmed Output.
The LM uses the difference in emitter-base voltage of. All of the components have already been mounted on the board and the board has been tested.
Original Heathkit sensor top and new replacement unit below. Stand the probe on end and allow all of the silicon seal to cure completely.
T O e Meter zero temperature K. Thermometer With Meter Output.
