RKI GX-2003 Calibration Guide:

Want to calibrate the RKI GX-2003? Here's how:

  1. Turn the RKI GX-2003 on in normal reading mode. Do this by pressing and holding the enter/power button.
  2. Once the RKI GX-2003 is in normal reading mode, you need to send it into calibration mode. Do this by pressing the display and shift buttons at the same time.
  3. Now that the screen is asking for confirmation, press the enter/power button once on Auto Calibration to confirm. This will send the monitor into zeroing mode. Now is a good time to set the monitor down, and grab your calibration gas, regulator, and calibration adapter.
  4. Connect your demand flow regulator.
  5. Attach the tubing to the hose barb on your regulator. Make sure the tubing is also connected to your calibration adapter.
  6. Make sure your calibration gas values on the screen match what is on your calibration gas cylinder!
  7. Once the RKI GX-2003 has reached the values or close to the calibrations gas, press the enter/power button. The screen should read auto calibration pass. Select normal operation mode.
  8. Congratulations! You have officially calibrated your RKI GX-2003 gas monitor. Make sure to record these readings in your calibration log!
