7 Introduction
Data & Event logger
• The controller automatically logs the process control information in an interval
log, and various event alarms and errors in an event log
•
Logged data can be retrieved and events visualized on the screen, in Log Recall menu
• Interval logs store up to 8600 records per lot, maximum lot number is 100 lots
• Logging interval can be set in the General settings menu
• Logged data includes:
` measurement variables and temperature measurements
` last calibration data
` setup configuration
` start/end date and time
` previous values
` event data and event code
• Event log can store up to 100 records of events, alarms, errors‑related data
• Log files can be uploaded to a USB flash drive via USB‑C port
Calibration
• pH
Up to three‑points standard calibration with selection from two buffer groups:
` Hanna Instruments: 1.68, 4.01, 7.01, 10.01, 12.45 pH
` NIST: 1.68, 4.01, 6.86, 9.18, 12.45 pH
• Conductivity
Up to two‑points user calibration with selectable calibration points:
` 0.000 μS/cm for offset
` 84.0 μS/cm, 1413 μS/cm, 5.00 mS/cm,12.88 mS/cm for 0.1/cm cell
` 80.0 mS/cm, 111.8 mS/cm additional standards for 1.0/cm cell
• DO (Dissolved Oxygen)
Up to two‑points standard calibration
• Single point process calibration for all supported parameters
•
Last calibration data stored on the probe and can be visualized in the Cal Data window
• Calibration reminder can be scheduled (1 to 99 days) or set as Off
Safety
• When in Setup or Calibration mode, without making any changes or pressing any
key, the controller will return to Measure mode and restart control.
