Clean the sensor
Do not use abrasive cleaners. Always use gloves to handle the piston or the sensor. Oil from hands will increase
the stabilization time.
Pre-requisites:
1. Put the controller in manual mode.
2. Disconnect power to the instrument.
Required items:
• Soft toothbrush or soft cloth
• Clean sample water
Procedure:
The frequency and cleaning method changes with conditions in the process water. The streaming
current is very sensitive to the surface condition of the piston. After the sensor is cleaned, the
stabilization time can be up to 30 minutes. Refer to the illustrated steps to clean the sensor.
