4 Measurement Basics
4.1 General information about conductivity measuring
During the measurement, the conductivity measuring cell must be dipped at least in so
far, that at least 30 mm beginning from the top of the measuring cell, is located in the
medium. The maximum immersion depth for continuous operation should not exceed
110 mm.
The measuring cell can either be stored dry or in water. After dry storage wetting time
will be prolonged slightly. If changing over from one liquid to another with conductivities
varying widely make sure to properly rinse and shake dry measuring cell.
If conductivity measured is much higher or lower than expected this may be due to the
electrode being soiled with non-conducting or conducting foreign materials. Measuring
cell has to be cleaned with a watery soap solution. When measuring media with low
conductivities the electrode has to be stirred sufficiently.
NOTE
Measuring cell must never come into contact with water-repellent materials such as oil
or silicone.
4.2 Conductivity measurement
The conductivity measurement is a comparatively uncomplicated measurement. The
standard electrodes are stable for correct use for a long time and can be calibrated
over the gradient correction.

5 Operation and maintenance
5.1 Operating and maintenance notices
_
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
desired, a gradient correction can be carried out for the product in order to further
optimise the accuracy in a narrow range. This is only necessary for normal use. See
Adjustment of the measuring input.
5.2 Battery
5.2.1 Battery indicator
_
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
adequate for operation of the product. The battery is fully depleted.
5.2.2 Changing battery
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!
_

Operating Manual RS 1410 page 11 of 20
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.
_
NOTE
This symbol indicates processes, which can have a direct influence on operation or
can trigger an unforeseen reaction in case of non-observance.
NOTE
Read the following handling instructions before replacing batteries and follow them
step by step.
If disregarded, the product could be damaged or the protection from moisture could be
diminished.
1. Unscrews the Phillips screws (A)and remove the cover.
2. Carefully replace the two Mignon AA batteries (B). En-
sure that the polarity is correct! It must be possible to in-
sert the batteries in the correct position without using
force.
3. The O-ring (C) must be undamaged, clean and posi-
tioned at the intended depth. In order to facilitate assem-
bly and avoid damage, a suitable grease can be applied.
4. Fit the cover on evenly. The O-ring must remain at the
intended depth!
5. Tighten the Phillips screws (A).

6.2 Adjustment of the measuring input
The temperature input can be adjusted with the zero point correction and the gradient
correction. If an adjustment is made, you change the pre-adjusted factory settings.
This is signalled with the T.OF, T.SL or S(L display text when the product is switched on.
1. The product is switched off
2. Press and hold the Down button.
3. Press the On/Off button to switch on the product and open the Configuration
menu. Release the Down button. The display shows the first parameter.
