Overview of Configuration Menu Structure of Configuration The device provides 2 parameter sets “A“ and “B“. By switching between the param- eter sets you can adapt the device to different measurement situations, for example. Parameter set “B“ only permits setting of process-related parameters. The configuration steps are assigned to different menu groups.
Automatic Calibration (Calimatic) The AUTO calibration mode and the type of temperature detection are selected during configuration. Make sure that the buffer solutions used correspond to the configured buffer set. Other buffer solutions, even those with the same nominal values, may demonstrate a differ- ent temperature response.

Please note: The measured value Stability check can [mV] is displayed, “CAL2” be stopped after and “enter” are blinking. 10 sec (by pressing enter). However, this Calibration with the first buffer is terminated. reduces calibration Remove the sensor and accuracy.
Product Calibration (pH) Calibration by sampling (one-point calibration). During product calibration the sensor remains in the process. The measurement process is only interrupted briefly. Procedure: 1) The sample is measured in the lab or directly on the site using a por- table meter.

Sensoface (Sensocheck must have been activated during configuration.) The smiley in the display (Sensoface) alerts to sensor problems ( defective sensor, sensor wear, defective cable, maintenance request). The permitted calibration ranges and the conditions for a happy, neutral, or sad Sensoface are summarized in the following table. Additional icons refer to the error cause.
Sensoface Display Problem Status Asymmetry Asymmetry potential (zero) potential and and slope of the sensor are slope still okay. The sensor should be replaced soon. Asymmetry potential and slope of the sensor have reached values which no lon- ger ensure proper calibration. Replace sensor.

Sensoface Display Problem Status Sensor wear High temperatures and pH values have caused a wear of over 80%. The sensor should be replaced soon. Wear is at 100%. Replace sensor. SENSOR WEAR Replace sensor AUTOCLAVE CYCLES Maximally permitted number of auto- OVERRUN claving cycles has been reached.
