Conductivity is the capacity of a solution to conduct electric current. It is ions that carry the charges. The more ions the solution
contains, the more current it will conduct.
Immerse the end of the cell in the solution, making sure that the sensitive part is completely immersed in the solution.
The instrument displays the measurement at the chosen
reference temperature (20 or 25°C). Wait for it to stabilize
before reading it on the instrument’s display unit.
16
3.3.1. USING ANOTHER CONDUCTIVITY CELL
The cell provided with the instrument has an integrated temperature probe. If you use another cell, one without an integrated
temperature sensor, you must measure the temperature of the solution.
Use a four-pole cell suited to the medium to be measured.
The instrument indicates that the temperature can be modied by displaying MTC next to the temperature
MTC = Manual Temperature Compensation.

Ref 20°C
You must then correct the temperature displayed, using the ▲ and ▼ keys, so that it is equal to the measured temperature of the
solution.
The instrument corrects the response of the cell as a function of the temperature.
To calibrate the cell, always correct the temperature rst.
To connect your cell, use an optional connection kit (see §1.2). These adapters also let you connect a PT1000 probe.
17
3.4. RESISTIVITY MEASUREMENT

3.6. SALINITY MEASUREMENT
The salinity measurement serves to evaluate the salt content of seawater. It is expressed in PSU (Practical Salinity Units).
The conversion from conductivity to salinity is done using the UNESCO formula (PSS-78), for a temperature of the solution ranging
from -2 to +35°C. Outside of this temperature range, the instrument displays O.L. The conductivity displayed is referred to 15°C.
You must rst calibrate the cell for conductivity and parameterize the measurements (in particular the temperature correction
and the reference temperature) before making salinity measurements.
Long-press the key to switch the instrument on.

3.7. RECORDING THE MEASUREMENTS
A short press on the MEM key records the measurement with the date and time. The MEM symbol is displayed briey.
It is not possible to record a single/an isolated measurement when/while the instrument is (already?) recording.
A long press on the REC key starts or stops a recording session. The REC symbol remains displayed for the duration of a
recording session. Auto o is deactivated (this means that the instrument is in permanent mode) and the P symbol is dis-
played.
Before starting a recording session, make sure that the battery life is sucient, or else connect the instrument to an external
power supply on/to a wall outlet using a micro USB cord.
When the memory is 90% full, the MEM FULL symbol blinks. When the memory is full, the MEM FULL symbol stops blinking.
To see the records, you must use a PC and install the Data Logger Transfer software (see §4).
3.8. ERRORS
The instrument detects errors and displays them in the form Er.XX. The main errors are the following:
Er.01: Hardware malfunction detected. The instrument must be sent in for repair.
Er.02: Error in internal memory. Format it using Windows.
Er.03: The update of the internal software is not compatible with the instrument (the software is that of another instrument of the
line). Install the correct internal software in your instrument.
Er.10: The instrument has not been calibrated or the calibration is not in conformity. The instrument must be sent back to customer
service.
Er.12: The update of the internal software is not compatible with the electronic boards in the instrument. Reload the previous
internal software into your instrument.
