Section 4 Preparation for use
Prepare the probe for calibration and measurement as follows. Do not touch the protective black
layer on the LDO sensor cap.
1. Remove the shroud. Refer to Remove or install the shroud on page 9.
2. Open the pressure sensor module cap and make sure that the label on the iButton is on top.
3. Make sure that the LDO sensor cap and iButton label have the same lot code. Refer to Figure 2.
4. Install the LDO sensor cap and tighten by hand. Do not tighten more than is necessary for a good
seal.
5. Soak the probe in 100 mL of tap water for 30 minutes before use. For probes that will be in
aqueous solutions for more than 6 hours continuously, soak the probe for 72 hours.
Note: After 72 hours, the LDO sensor cap is fully hydrated.
6. Make sure that the meter has the correct date and time settings. The service-life time stamp in
the probe comes from the date and time settings in the meter.
Note: Some meters automatically open the date and time settings when the meter starts for the first time, or
after battery replacement.
7. Connect the probe to the meter.
8. Install the shroud. Refer to Remove or install the shroud on page 9.
Note: Make sure to install the shroud during field use to prevent damage to the sensing elements. The product
warranty does not include such damage.
