ABSTRACT:
A cycle time/temperature controller for a combination corrosion tester includes a device for setting a loop number and a number of repetitions of that loop, a device for setting a sequence of test items within a loop including: a test temperature, a test humidity, and an operating time; the controller also includes a generator for generating an operative signal and a device for enabling the start of operation according to an external start signal and an output circuit for outputting a contact output corresponding to each test item for the set operating time; adjustment outputs for dry bulb and wet bulb temperatures are also provided, each output providing adjustments at the set test temperature and the set test humidity. The controller displays the current loop number and the number of repetitions and also displays: the test item number, the dry bulb temperature, the wet bulb temperature, the wet bulb temperature or humidity, and the time elapsed, during its operation.
