Replacing the Shroud
1. Place the locking ring ( Figure 2 , item 2 ) on the probe body with the threads toward the
shroud ( Figure 2 , item 1 ).
2. Slide the shroud onto the probe until the locking ribs ( Figure 2 , item 4 ) are seated in
the locking groove ( Figure 2 , item 7 ).
3. Screw the locking ring onto the threads.
4. Hold the shroud and hand-tighten the locking ring.
Calibration
Each lot of LDO sensor caps is factory-calibrated. For best performance, a one-time
calibration initialization can be performed when a new sensor is installed. Additional
calibrations can be performed but are not required.
For calibration steps, refer to the HQ Portable Meters User Manual. The IntelliCAL™
probes store the current calibration and calibration history in the probe memory. It is not
necessary to recalibrate when moving a calibrated probe from one meter to another.
