A Wide Array of Useful Functions

• Source
  Values set in steps of 4-20 mA 24V DC Power Supply to Transmitter
• Divided output (n/m) function
  Output settings are divided, eliminating the need for bothersome calculations for percentage output.
• Autostep function
  Changes the output value in step form based on the setting from the divided output (n/m) function. Changes can be sourced automatically every 10% or 25%.
• Online communication (CA71 only) RS-232C-compliant optically isolated interface
• Sweep function
  Linearly increases or decrease the output. The increasing/decreasing time can be set to either 16 or 32 seconds.
• Memory function
  Source values and measurements forming individual value sets can be saved to or read from the Handy Calibrator's internal memory (maximum 50 value sets).
• Temperature monitor function
