3. USE IN STAND-ALONE MODE
The instrument can operate in two modes:
the stand-alone mode described in this section,
the record mode, in which it is controlled by a PC. This mode is described in the next section.
To ensure proper operation of the instrument, always leave the cell connected and the cap on the USB connector.
3.1. CONNECTING THE CELL
When you rst use the instrument, connect the conductivity cell provided to the measuring instrument. Connect the connector of
the cell to the instrument and screw the ring all the way on.
3.2. CALIBRATION
3.2.1. PARAMETERIZING THE MEASUREMENTS
Before calibrating the cell, you can set various parameters.
The unit of temperature (°C or °F)
The reference temperature, 20 or 25°C (68 or 77°F). This is the temperature to which the measurement will be referred.
The temperature correction used to correct and display the measured conductivity as of the chosen reference temperature.
This is useful because the conductivity of a solution increases with increasing temperature.
cor lin: linear temperature correction
The measured conductivity is corrected and displayed using the following formula:
Σdisplayed = σT / (1 + α (T - Tref) / 100%)
where: σdisplayed = the conductivity displayed by the instrument.
σ
T= the conductivity measured at temperature T.
α = the linear temperature correction coe󰀩cient.
T = the measured temperature (°C)
Tref = the reference temperature (20 or 25°C)
Acids: 1 to 1.6%/°C
Bases: 1.8 to 2.2%/°C
Salts: 2.2 to 3.0%/°C
Drinking water: 2.0%/°C
Ultra-pure water: 5.2%/°C
no cor: no correction, α = 0%/°C.
cor f(T): nonlinear temperature correction. See appendix 1 in §8.
TDS factor (f): between 0.40 and 1.00. This is used to calculate TDS (Total Dissolved Solids). It is expressed in mg/l or in ppm.
TDS = σ.f

It performs the conductivity measurement and indicates its progress.
During the calibrations, the cell coe󰀩cient for a given cell must vary only a little. If you observe a large variation, it may be
necessary to redo the calibration, check the condition of the standard solution (in particular the use-by date), or replace the
cell.

16
If you do not want to restore the initial calibration, choose no before pressing the CAL key.
Otherwise, choose YES and press the CAL key. The cell coe󰀩cient returns to 1.000.
3.3. CONDUCTIVITY MEASUREMENT
When the calibration is over, the cell is ready to make measurements.
Use a cell suited to the medium to be measured.
Between measurements, the cell must be rinsed, then dried.
For each measurement, wait for the measurement to stabilize and for the temperature to be correctly established.
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.

reference temperature (20 or 25°C). Wait for it to stabilize
before reading it on the instrument’s display unit.

17
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.

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 modied by displaying MTC next to the temperature

3.4. RESISTIVITY MEASUREMENT
Resistivity is the reciprocal of conductivity.

Long-press the key to switch the instrument on.
Press the key to switch to resistivity measurement.

3.5. TDS MEASUREMENT
The TDS (Total Dissolved Solids) measurement is used to estimate the level of dissolved solids in a solution.
You must rst calibrate the cell for conductivity and parameterize the measurements (in particular the temperature correction,
the reference temperature, and the TDS factor) before making TDS measurements.

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.

Before starting a recording session, make sure that the battery life is su󰀩cient, 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.
Er.13: Recording scheduling error. Check that the instrument’s time and the time of the Data Logger Transfer software are the
same.
Er.14: Calibration error. The measured value is too far from the value of the standard solution of the selected calibration set. Check
that the solution used in fact belongs to the selected set. If necessary, return to the initial calibration (see § 3.2.4).
Er.15: Calibration error. The stabilization time is too long.
Er.19: Calibration error. The temperature (ATC or MTC) is outside of the specications of the standard solutions. Redo the cali-
bration in a room where the temperature lies within the specications of the standard solution (see the Set.csv le, §4.3).
Er.20: Calibration error. The le dening the set of calibration solutions is missing. Download it from our web site:
www.chauvin-arnoux.com
Er.21: Calibration error. The le dening the set of calibration solutions is not in conformity. Check that it is the right le. If you have
modied it, check the format; in particular, the decimal separators must be points, not commas.
Er.22: Recording error. Power was cut o󰀨 while recording was in progress.
Er.50: Calibration error. Measurement error for the calibration.
To exit from calibration errors, press the CAL key or the END key.
