Filling the membrane cap with electrolyte
Please note the information on the safety data sheet to ensure safe use of the electrolyte.
NOTICE
Damage to membrane and electrodes, air bubbles
Possibility of measured errors to complete failure of the measuring point
‣
Avoid damage to membrane and electrodes.
‣
The electrolyte is chemically neutral and is not hazardous to health. Nonetheless, do not
swallow it and avoid contact with eyes.
‣
Keep the electrolyte bottle closed after use. Do not transfer electrolyte to other vessels.
‣
Do not store electrolyte for longer than one year. The electrolyte must not be yellow in
color. Observe the use-by date on the label.
‣
Avoid air bubbles when pouring electrolyte into membrane cap.
‣
Only use membrane cap once.
‣
Store the electrolyte bottle upside down (standing on its head) to ensure that the viscous
electrolyte can be decanted as easily as possible with minimum bubbles. Smaller air bubbles
are not a problem. Larger air bubbles rise to the upper edge of the membrane cap.
Filling the membrane cap with electrolyte
The sensor is dry when delivered from the factory. Before using the sensor, fill the
membrane cap with electrolyte.
1. Open the electrolyte bottle. Screw the nozzle onto the electrolyte bottle.
2. Press out any excess air.
3. Place the electrolyte bottle on the membrane cap.
4. Using a single movement, slowly push the electrolyte into the membrane cap until it
reaches the lower turn of the thread. Withdraw the electrolyte bottle smoothly.
5. Slowly screw on membrane cap up to the stop . This will cause excess electrolyte to be
displaced at the valve and thread.
6. If necessary, pat the sensor and membrane cap dry using a cloth.
7. Thoroughly clean the nozzle with a clean, warm and strong jet of water to ensure that
any electrolyte is removed.
8. Reset operating hours counter for electrolyte on transmitter. For detailed information,
see Operating Instructions for transmitter.
