Before you take a reading, make sure the pen is clean, calibrated, in the appropriate measurement mode and connected to the App. The sample solution must also be within the specified measurement range. Keep all foreign material away from the sample to avoid contamination.

NOTE: If you cannot dip the pen in the sample solution, pour the sample into a clean container. If you don’t have a sample container and need to test a vertical stream of solution, use the scoop. The following table explains the LED Indicator signals and typical durations.

CAUTION: To measure solution at the extremes of the specified temperature range, allow the pen to equilibrate by submerging the cell in the sample solution for 1 minute prior to taking a measurement.

  1. PTBT1 UltrapenRinse the cell by swirling it in fresh solution sample.
  2. Open the ULTRAPEN App. If it does not open to the Measurement screen, tap the Measurement button in the Feature Navigation Bar. The Measurement screen will say, “Paired ULTRAPEN is Offline”.

  5. Press and release the PTBT1’s push button to turn it ON.
  6. When the LED flashes rapidly, IMMEDIATELY dip the pen in the sample solution so that the cell is completely submerged. (If you do not submerge the cell in solution before the flashing slows, allow the pen to power off and retake the reading).
  7. The App screen will display “Measuring …”
  8. When the LED flashes slowly, swirl the pen to remove bubbles, keeping the cell submerged and preferably at least 1 inch (2½ cm) away from sides/bottom of container.
  9. When the LED turns Solid ON, the App display will show the measurement and temperature. Remove the pen from solution and rinse it in clean water.
  10. The ULTRAPEN will turn OFF once the measurement is completed.
