The ADAPT is a novel way of connecting sensors and sources to measuring equipment such as platinum resistance thermometers (PRTs) to a temperature indicator. 

Use 1:  The ADAPT can be used as a break-out box to connect 1 or 2 resistance thermometers to a single channel of a temperature indicator or a logger.
Use 2: As Use 1 above but connecting resistors into a meter.
Use 3:  Connecting 1 or 2 voltage signals to a voltmeter.
Use 4:  The ADAPT can be used to do simulation calibrations of resistance thermometer based temperature indicators.
Use 5:  One set of terminals can be shorted together to be used for ‘zeroing’ a meter whilst the other set of terminals are used as the signal input.
Use 6:  Calibration of 3-wire PRTs using a 4-wire resistance meter can be performed.
