NOTE
The product and conductivity measuring cell must be handled with care and used in
accordance with the technical data. Do not throw or strike.
NOTE
If the product is stored at a temperature above 50 °C, or is not used for an extended
period of time, the batteries must be removed. Leaks from the batteries are avoided as
a result.
The device is calibrated at the factory with the permanently connected conductivity
measuring cell. The highest system precision can be achieved in this manner. If de-
sired, a gradient correction can be carried out for the product in order to further optim-
ise the accuracy in a narrow range. This is only necessary for normal use. See Adjust-
ment of the measuring input [} p. 19].
If the empty frame in the battery display blinks, the batteries are depleted and must be
replaced. However, the device will still operate for a certain length of time.
If the BAT display text appears in the main display, the battery voltage is no longer ad-
equate for operation of the product. Now the battery is fully depleted.
DANGER
Danger of explosion!
Using damaged or unsuitable batteries can generate heat, which can cause the batter-
ies to crack and possibly explode!
– Only use high-quality and suitable alkaline batteries!
CAUTION
Damage!
If the batteries have different charge levels, leaks and thus damage to the product can
occur.
– Use new, high-quality batteries!
– Do not use different types of batteries!
– Remove depleted batteries and dispose of them at a suitable collection point!
