      Get started: 

      Step 1: Powering up your Bluelab OnePen

      1. Press "O" button to power the Bluelab OnePen ON.
      2. Hold the "O" button to power off the Bluelab OnePen. Release once backlight has turned off.

      Step 2: Set units

      Conductivity
      1. Press and hold both "O" and "CAL" buttons together.
      2. After 3 seconds it will enter units mode. Use the "CAL" button to cycle through available units: EC, CF, PPM500, PPM700 and mS/cm. Selected unit will be flashing on the screen.
      3. Press "O" when desired unit is flashing to save and move onto Temperature unit selection
      Temperature
      1. Use the "CAL" button to cycle through available units: °C, and °F. Selected unit will be flashing on the screen.
      2. Press "O" when desired unit is flashing to save and exit units mode.

      Step 3: Toggle through measurement modes

      Press "CAL" button to cycle through measurement modes.

      Available modes are: EC/pH, pH/Temp, EC/Temp, and mV/Temp (when enabled via Edenic).

      Current measurement mode is indicated by units displayed on the screen.

      Step 4: Calibrate pH

      pH calibration is important before first use to ensure accurate readings.

      Note: It is recommended to hydrate the pH bulb in Bluelab KCl storage solution for 24hours before initial calibration, to ensure that the glass bulb is active.

      IMPORTANT: Always use fresh calibration solutions when calibrating your OnePen.

      1. Select pH/Temp measurement mode via the "CAL" button. Make sure pH reading is displayed on the main display.
      2. To calibrate to pH7, submerge probe tip in fresh pH7 Calibration Solution, wait a few minutes for the probe to come to the same temperature as the solution.
      3. Hold the "CAL" button until “CAL” displays, then release. Wait until •‘s stop flashing from left to right, stops flashing and “PASS PH7” displays.
      4. Rinse in fresh tap water.
      5. To calibrate to pH4, submerge probe tip in fresh pH4 Calibration Solution & hold the "CAL" button until “CAL” displays, then release. Wait until •‘s stop flashing from left to right, stops flashing and “PASS PH4” displays.
      6. On a successful two-point calibration the following icons will be displayed:
        1.  Successfully calibrated
        2. Calibration status
        3. pH7 calibrated
        4. pH4 calibrated

      Note: Can also be calibrated to pH7 and pH10.

      Step 5: Take a measurement

      1. Select desired measurement mode via "CAL" Button.
      2. Press the "O" button to save a measurement. The measurement will be held on the screen for 10 seconds.
      3. Press the "CAL" button to cycle through measurement screens while in hold.
      4. Either wait 10 seconds for the OnePen to exit hold or press the "O" button again to exit.

      Note: All three parameters saved to Pen to sync with Edenic.

      Step 6: Connect to Edenic by Bluelab software

      2. Turn the pen upside down to ensure the batteries remain in place.
      3. Unscrew the threaded collar and remove the old probe from the pen body.
      4. Remove the protective cap on the new probe.
      5. Carefully replace the probe in the pen, lining up the arrow on the top side of the probe with the corresponding notch on the pen body.
      6. Push the probe all the way in. The arrow should sit perfectly into the notch.
      7. Secure probe with the threaded collar. Twist to tighten.
