AC Voltage measurement capablity (including supply voltage)
In cases where numerous signal converters and other devices are mounted on a rack or panel, the Handy Calibrator can be used to check the input and output signals of each device, while simultaneously checking the power supply. There is no need for a separate multimeter to measure supply voltage.

Easy operation
The Handy Calibrator incorporates rotary switches for simple handling. Just open the carrying case cover and connect the cables, and you're ready to take measurements.

• Source:
  Values set in steps of 4-20 mA24V DC Power Supply to Transmitter
• Divided output (n/m) function
  Output settings are divided, eliminating the need for bothersome calculations for percentage output.
• Auto-step 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
  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
