Product Specifications:

  • Source and Measuring of Voltage and Current:
    General and measures voltages up to 30V DC and current up to 24 mA DC
  • 4-20 mA and 1-5 VDC Step-up/down Function:
  • The output level can be changed between 1↔2↔3↔4↔5V signals for the 1 to 5V DC output, for efficient calibration work.
  • 20 mA SINK Function:
    Absorb the voltage supplied from an external power supply to its H terminal and simulates a two-wire transmitter, idea for loop checks.
  • Sweep Function:
    Increase and decrease the output level to the preset level at a constant rate for the selected sweep time (16 or 32 seconds). The sweep function and sweep time are set by the internal dip switch.
