44422A HP Data Logger

Used

Additional Features:

  • Relay Multiplexer with Thermocouple Compensation
  • Consists of reed actuated relays that switch High, Low, and Guard on each of twenty channels
  • Inputs to the relay card are provided by terminal connector cards, one of which has thermocouple compensation built in

Two types of compensation (selectable by the user) are available. A temperature-dependent voltage is generated for software compensation; this voltage is then used in a computer program to compensate the thermocouple voltage. Hardware compensation involves inserting a voltage in the measurement circuit that automatically compensates the thermocouple voltage.
