ULTRAPEN™ PX SENSOR REPLACEMENT INSTRUCTIONS
For ULTRAPEN models PT2, PT3, PT4, PT6, PTBT2, PTBT3, PTBT4 and PTBT6
Not for PT5 or PTBT5, see PT5/PTBT5 Sensor Replacement Instructions.
NOTE: Please read these instructions thoroughly and carefully — Damage caused by improper installation or mishandling will void
the warranties of the instrument and the new sensor.
CAUTION: Moisture trapped in instrument will cause damage to the electronic circuitry. Careful adherence to the following
procedure will significantly reduce the potential for failure due to moisture contamination or damaged connectors.
CAUTION: AVOID TOUCHING AND/OR CONTAMINATING THE ULTRAPEN ELECTRONICS OR SENSOR CONNECTOR/
CIRCUITRY AT ALL TIMES!
For clarity, this procedure is broken down into three sections.
Follow each section carefully to avoid damage.
Refer to images as
necessary. All images are of model PT2 for example.

Preparation of ULTRAPEN
1.
Before removing the sensor from the ULTRAPEN, remove the protective/hydration cap from your ULTRAPEN by
wiggling it side to side while gently pulling it off the ULTRAPEN, use caution not to spill solution.
2.
Rinse the sensor end and surrounding area with clean water and dry thoroughly.
3.
Ensure hands are clean and dry. Moisture will damage the electronics.
4.
Unscrew the battery cap and remove the battery tray. (There is a pressure relief tube running from the battery
compartment to the sensor compartment, which allows pressure equalization in the sensor area.)
5.
Grasp the sensor body and gently pull the sensor out of the ULTRAPEN.
6.
Carefully clean off any residual salt or liquid around the opening of the ULTRAPEN’s sensor compartment using a
towel. CAUTION: Do NOT contaminate the inside of the ULTRAPEN.
