LDO101-01 or LDO101-03 Probe
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 electrode from one meter to another.
Maintenance
Important Note: Do not scrub the sensor cap or the sensor lens.
Important Note: Do not use organic solvent solutions such as acetone or methanol with
the LDO101 sensor cap. These solvents will damage the plastic sensor cap.
General Maintenance
• After use, visually inspect the sensor cap ( Figure 2 , item 3 ). Use optical tissue or a
cotton swab with soapy water to clean the sensor cap. Rinse with fresh water.
• Before measuring a new sample, rinse the electrode with deionized water and blot dry
with a paper towel.
• If the cap is sealed properly using the top O-ring seal ( Figure 2 , item 4 ), no water
should be present between the sensor cap and the clear plastic sensor lens ( Figure 2 ,
item 5 ) at the top of the probe. If water is present, remove the cap and thoroughly dry
the inside of the cap and the clear plastic sensor lens. The cap may require
replacement (Cat. No. 58112-00).
Storage
• Between uses, store the probe dry in ambient conditions.
