Preparing the New Sensor
Steps 1 and 2 should be performed AWAY from the ULTRAPEN.
CAUTION: The protective/hydration caps on the PT2, PT3, PT4, PTBT2, PTBT3 and PTBT4 ULTRAPENs contain a small amount of
concentrated saline storage solution that will cause damage if allowed to come in contact with the ULTRAPEN’s electronics or sensor
connector/circuitry.
NOTE: The O-rings of the sensor are pre-greased for ease of insertion. Carefully remove any packaging
from the shaft before installation and handle the sensor by the protective/hydration cap end to avoid
migration of the grease.
1.
Holding the new sensor, remove the warning label from around the protective/hydration cap. Then remove the
clear tape from around the top of the protective/hydration cap.
2.
If there are salt crystals around the cap of the sensor, using caution not to allow the connector side of the sensor
to get wet or contaminated, carefully rinse sensor with clean water, shake off excess water, and dry the outside of
the sensor body. Remove the connector cap from the connector end of the sensor and inspect to ensure 3 O-rings
are on the sensor body.

Installing the New Sensor
1.
Align the Large and Small alignment tabs on the sensor with the Large and Small grooves on the ULTRAPEN.
(It will only go in one way.) WARNING: Damage WILL occur to the connectors inside your ULTRAPEN if you
attempt to install the sensor incorrectly.
2.
While maintaining alignment, gently apply pressure to insert the sensor into the ULTRAPEN. You may need to
apply a slight twisting motion to start each O-ring, ensuring all 3 O-rings on sensor slide evenly into ULTRAPEN.
CAUTION: A damaged O-ring will allow solution to leak into the instrument. Press sensor STRAIGHT into the
ULTRAPEN until it is securely in place.
3.
Replace the battery tray by aligning the groove in the side of the enclosure with the groove in the battery tray, then
sliding the tray into the case until it is fully seated. The groove in the case corresponds to a guide bump inside the
enclosure that guides the tray back into the correct position. Screw the battery cap back on.
Your instrument is now ready for calibration. See Operation Manual for calibration instructions.
