Preparing A Ph Electrode - Testo 252 Bedienungsanleitung

Make sure there is
pressure compensation
during measurement
with type 02 and 05.
Hold the ring of
the probe
sleeve adapter
Remove the
storage cap
Remove air bubbles
by shaking (type 02
and 05).
Check the level of
the electrolyte
Only for type 02 and type 05:
In order to guarantee pressure compen-
sation, the refill opening should be open for
the duration of the measurement.
- Remove the storage cap. Keep hold of the
probe sleeve adapter ring and remove the
storage cap by turning.
- Rinse the electrode in water and blot dry with
tissue paper. Rubbing the electrode dry can
considerably prolong the response time of the
electrode due to static charging.
Only for type 02 and type 05:
Check the inside of the glass membrane for air
bubbles. Remove any bubbles present by
carefully shaking the electrode up and down.
- Check the level of the electrolyte in the
electrode. Add more electrolyte should the level
drop below 20 mm from the refill opening.
Make sure that the correct electrolyte
solution (type 02/05) is used.
Should any electrolyte solution be spilt,
wipe it up immediately with a damp
cloth. Electrolyte solutions can
damage metal and electrical parts.
The electrode is now ready for use.
