12. Operating Modes
Measurement Mode
This is the standard mode for the application when it is paired with an actively measuring ULTRAPEN instrument.
Stand Alone Mode
●This operating mode allows you to access the previous measurement data stored in mobile device when:
○The application isnot currently paired with an instrument.
○The currently paired instrument is asleep or out of broadcast range.
●At startup:When the application starts up and is already paired to an ULTRAPEN instrument that is currently inactive:
○If the App is not paired to an ULTRAPEN the main Measurement screen will display, "No Paired ULTRAPEN".
○If the App is paired to an ULTRAPEN the main Measurement screen will display, "Paired ULTRAPEN is offline."
●Continuing use:Once the application has been operating and has received measurements from an active ULTRAPEN that is
currently inactive, the Stand Alone screen will:
○Display "Paired ULTRAPEN is Offline" in the Measurement display area.
○Display the most recent measured value taken with the currently paired ULTRAPEN.

13. Making Measurements – General
Before you take a reading, make sure the ULTRAPEN sensor is clean, and the instrument is 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 ULTRAPEN 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 (see the section titled:Using the Scoop).
CAUTIONS:
●PTBT2 and PTBT3: When measuring a solution at the extremes of the specified temperature, allow the pen to equilibrate by
submerging the cell in the sample solution of the same temperature for 1 minute prior to taking a measurement.
●PTBT3 ONLY: When moving from solutions with high to low ionic strength, allow the pen to equilibrate by submerging the cell in
the sample solution of the same temperature for 1 minute prior to taking a measurement. In some applications you may want
to allow the sensor to soak longer, until equilibrium with the solution is reached.

1. Rinse the sensor by swirling it around in fresh sample solution(see Caution in Section 13 above).
2. Open the PTBTx 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."
3. Grasp the ULTRAPEN near the battery cap to avoid sample contaminating the current sample.
4. Remove ULTRAPEN from the rinse solution, then press and release the ULTRAPEN's push button.
5. When the LED flashes rapidly, IMMEDIATELY dip the ULTRAPEN in fresh sample so that the cell is completely submerged.
○If you do not submerge the cell in solution before the flashing slows, allow the ULTRAPEN to power off. Retake the reading.
6. When the LED flashes slowly, swirl the ULTRAPEN around to remove bubbles, keeping the cell submerged.
○Keep the ULTRAPEN at least 1 inch (2½cm) away from sides/bottom of container, if possible.
7. When the LED turns Solid ON, remove the ULTRAPEN from solution.
○The App display will show the measurement and temperature values.
8. The ULTRAPEN will turn off once the measurement is completed.
9. The value will be held on the App Measurement Screen.
○The value will be grayed out.
○"Pen is Offline" will appear to the upper right of the measured value.
15. Using the Scoop
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 or
need to test a vertical stream of solution, use the scoop.
To use the scoop:
●Slide open end of scoop over bottom of ULTRAPEN shifting from side-to-side until the neck of the scoop is flush with the top of the
cell.
●Hold scoop under stream and perform the measurement as normal. Avoid bubbles.
●We recommend calibrating the ULTRAPEN using the scoop to retain ±1% accuracy.
●To remove, pull the scoop off while shifting side-to-side.
○If the sensor is not fully seated in the PTBT4, reinstall per pH Sensor Replacement (seepH/ORP Sensor Replacement).
