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.
