Memosens Cable CA/MS-... Intended Use Connecting cable for contactless inductive digital transmission of measured signals (Memosens®). The connecting cable consists of an inductive connector for digital Memosens® sensors (bayonet lock). It allows connecting the ferrule- terminated wires from the sensor loop of the transmitter. Contactless inductive digital transmission of signals and energy eliminates the influence of humidity, electromagnetic fields and corrosion.

PH Calibration Please note: • All calibration procedures must be performed by trained personnel. Incorrectly set parameters may go unnoticed, but change the measuring properties. • The response time of the sensor and temperature probe is considerably reduced when the sensor is first moved about in the buffer solution and then held still.
Selecting a Calibration Mode Calibration is used to adapt the device to the individual sensor characteristics, namely asymmetry potential and slope. Access to calibration can be protected with a passcode (SERVICE menu).

OXY Calibration Calibration adapts the device to the individual sensor characteristics. It is always recommended to calibrate in air. Compared to water, air is a calibration medium which is easy to handle, stable, and thus safe. In the most cases, however, the sensor must be removed for a calibration in air.
Selecting a Calibration Mode Calibration is used to adapt the device to the individual sensor characteristics, namely zero point and slope. Access to calibration can be protected with a passcode (SERVICE menu). First, you open the calibration menu and select the calibration mode: CAL_WTR / Calibration in water/air (as configured)

Sensoface (Sensocheck must have been activated during configuration.) The smiley in the display (Sensoface) alerts to sensor problems (defective sensor, sensor wear, maintenance request). The permitted calibration ranges and the conditions for a friendly, 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.
