    Conventions Used in this Manual ITALICS are used for texts which appear in the Portamess® 913 (X) Cond display. Bold print is used to represent the texts of keys, e.g. cal. Display examples keys whose functions are explained are frequently shown in the left-hand column.
  • Page 4 1 The Model 913 (X) Cond Package contents Please check the completeness of the shipment after unpacking. The package should include: • Portamess® 913 (X) Cond incl. batteries and sensor container • Carrying strap • User manual • Quickstart instructions in German, English and French •...
  • Page 5 • The data logger records up to 100 measured values with the temperature, date and time. Recording can be done either manually, interval or event-controlled. • To minimize battery consumption, the meter switches off automatically when it is not operated for either one hour or twelve hours.

After power-on, the meter automatically carries out a self-test and adjusts itself to the connected temperature detector.
  • Page 8 Pressing cal starts calibration. With ▲ and ▼ you can select and change parameters ▲ ▼ and select a mode. Pressing clock switches the meter into the clock mode. All measurement processes are canceled and the battery consumption is reduced to a minimum. Pressing STO records the measured value in the display and stores it in the data memory.

    Connection and start-up Sensor The following sensors from the line of accessories can be connection connected to the meter. SE 202 2-electrode sensor with integrated NTC 30 kΩ temperature detector SE 204 4-electrode sensor with integrated NTC 30 kΩ temperature detector Connection Connection ..........Socket assignment...
  • Page 10 Note If the meter is connected to a PC and is used to take measurements in a grounded liquid, measuring errors may result. Note Prior to first use, the cell constant, temperature com- pensation and time and date must be checked and set, if required.
  • Page 11 Configuration The following basic settings can be changed in the configuration: Function: Cond (conductivity), SAL (salinity) or tdS (Total Dissolved Solids or evaporation residue) • Calibration by entering the cell constant (AutCAL Off) or calibration with calibration solution (AutCAL On) •...

Automatic To protect the batteries, the meter switches off switch-off automatically when not operated for a longer time. You can select whether switch-off is to take place after one hour or after twelve hours (default setting: 1 hour).
  • Page 13 Date and time You can choose between the display format 24 hours format and day.month.year and the format 12 hours a.m./p.m. and month.day.year. (Default setting: 24 hours and day.month.year) Operation...
  • Page 14 Calibration By calibration, the Portamess® 913 (X) Cond is adjusted to the cell constant of the sensor. It is generally sufficient to enter the cell constant specified by the sensor manufacturer. General information on calibration Calibration Solutions for calibration of conductivity measuring devices solutions are unbuffered systems.
  • Page 15 SE 202 and For the conductivity sensor models SE 202 and SE 204, the SE 204 sensors cell constant is specified with a tolerance of 2 % and 1.5 %. This cell constant is entered and stored in the calibration mode (AutCAL OFF).
  • Page 16 Calibration with 0.1 or 0.01 molar KCl solution (AutCAL On) Note Impurities must always be prevented from getting into the calibration solutions. Pressing cal activates calibration. Calibration can be exited again by pressing meas. Then, the cell constant of the last calibration is displayed briefly. Select the calibration solution used (CALSoL).
  • Page 17 Calibration with any calibration solution (AutCAL On) Note Impurities must always be prevented from getting into the calibration solutions. Pressing cal activates calibration. Calibration can be exited again by pressing meas. Then, the cell constant of the last calibration is displayed briefly. First confirm any of the 0.1 or 0.01 mol/l KCl solutions (CALSoL) by pressing cal.
  • Page 18 Measurement Measuring Pressing meas accesses the measuring mode from all func- mode tions. In the measuring mode, the main display indicates the measured variable and the secondary display shows the temperature. Note If the Portamess® 913 (X) Cond is connected to a PC and measurements are taken in a grounded liquid, measuring errors may result.
  • Page 19 Measuring the salinity (SAL) The main display indicates the measured salinity in ‰ (g/kg), the secondary display shows the temperature. TDS determination (TDS) The main display indicates the concentration of the dissolved solids contributing to the solution conductivity (TDS, comparable to the evaporation residue) in mg/l, the secondary display the temperature.

  • Page 20: Data Memory

    Data memory Up to one hundred measured values can be saved in the data memory together with the temperature, date and time. Storage is performed either manually or automati- cally using the data logger. The currently measured value is stored. Write memory Press STO.

  • Page 21: Data Logger

    Data logger Data logger The data logger records up to 100 measured values together with temperature, time and date. Data storage is performed either manually (at the press of a key), inter- val- or event-controlled. The data logger always saves the currently measured variable.
  • Page 22 Setting the data logger parameters In the parameter setting mode, you select whether data logging is to be interval-controlled, event-controlled or manual. Press STO to access the logging functions. To select interval-controlled logging of measured values, press STO and set the interval in which the recording is to take place using and .

  • Page 23: Clock Mode

    Clock mode Pressing clock exits the measuring mode, or enters the clock mode with the meter switched off. The time and date are displayed. In this mode the battery consumption of the meter is reduced to a minimum. Setting clock To set the time or date, the clock mode must be activated.

  • Page 24: Serial Interface

    Serial interface Note If the meter is connected to a PC and measurements are taken in a grounded liquid, measuring errors may result. With the remote interface, you can directly send data to a printer with serial port or set up a direct connection to a personal computer.
  • Page 25 Interface Only one interface cable is required to operate with a cable printer or PC. By simply turning the plug around on the meter’s interface port, the cable can be used to connect either printer or PC. The label facing the operator should match the output device being connected.
  • Page 26 Note If the permissible measurement or temperature range has been exceeded during data logging or if the clock has not been set, the line on the printout will be marked with “#”. If temperature compensation was active during data log- ging, the line on the printout will be marked with “!”.

  • Page 30: Maintenance

    4 Maintenance Changing the batteries When the battery symbol appears in the display, the batter- ies need replacement. However, the meter can still be used for a few days. When the battery voltage continues to drop, the meter will switch itself off. Never change the batteries within a hazardous area.
