Operation; A) First Commissioning; B) Replacing The Measuring Probe - VOLTCRAFT KBM-100 Bedienungsanleitung

10. OPERATION

a) first commissioning

The electrode of the pH measuring probe always must be kept moist to be able to deliver
accurate measuring results for a long period of time.
If a small amount of liquid is in the protective cap of the pH measuring probe at delivery
because of this, this is normal. If no liquid is visible, you need to fill it into the protective
cap after initial commissioning.
For this, add a little bit of the enclosed storage solution into the protective cap and
screw the protective cap onto the pH-measuring probe. The electrode of the pH measur-
ing probe must not dry out anymore after initial commissioning.
The same applies to the electrode of the ORP measuring probe (not enclosed, can be
ordered as an accessory).
Observe that the protective flap with the storage solution in it does not tip over. If this
has happened, wipe off the liquid with an absorbent cloth and put the cloth into the regu-
lar household waste. Wash your hands with water and soap carefully.
If the storage solution is used up, you can purchase more as an accessory.
The electrode of the pH measuring probe is a wear part. Its service life is limited. For this
reason, the pH measuring probe is not included in the warranty/guarantee.

b) Replacing the measuring probe

• Switch off the combination meter
• Loosen the cap nut (6) and take it off.
• Axially remove the present measuring probe from the combination meter; do not cant it. The
measuring probe can be removed with very little effort; do not apply any force!
• Plug another measuring probe into the combination meter. Observe that the slot in the hous-
ing points forward to the display so that it can be pushed open easily.
• Put on the cap nut (6) in the right direction and tighten it manually. Do not use any tools and
do not apply any force.
