Sample measurement
Before measurement:
The probe must have the correct service-life time stamp. Set the date and time in the meter before the probe is attached.
If complete traceability is necessary, enter a sample ID and operator ID before measurement. Refer to the HQd meter
manual for more information.
Regular calibration is required for the best measurement accuracy (refer to
on page 3).
Prepare the probe for use (refer to
Make sure that the platinum disc is clean and smooth (refer to
on page 11).
To deploy a rugged probe at a distance, toss the probe body with a gentle underhand throw. Do not swing the probe by the
cable as this may cause injury to the user, will cause severe strain on the cable and will shorten the service life of the cell.
Damage under these conditions is not covered by the product warranty.
Measurement notes:
•
Data is automatically stored in the data log when Press to Read or Interval is
selected in the Measurement Mode. When Continuous is selected, data will only be
stored when Store is selected.
•
Air bubbles under the sensor tip when submerged can cause slow response or error
in measurement. If bubbles are present, gently shake the probe until bubbles are
removed.
•
If a measurement error occurs, refer to
on page 12.
