620G Cylinder Scales Line Powered 0-5V 3-Wire

To check the output:

  1. Connect the RED wire to a 24V DC outlet.
  2. Connect the BLACK wire to GROUND.
  3. You will now have 0-5VDC output coming from the WHITE wire with reference to COMMON (GREEN wire)
  4. Use a Voltmeter or a digital multimeter to check the voltage on the WHITE wire. Connect the multimeter as shown.
  5. Press the platform to see the deflection in current.
  6. Use the SPAN and ZERO potentiometers located on the side of the board to calibrate your platform current output.
  7. Connect the GROUNDING WIRE (bare) to a suitable Earth Ground location in your building.

Refer to enclosed calibration document on how to use the span and zero trimmers to calibrate your scale (if needed)
