Overview of the Portavo 902 COND The Portavo 902 COND is a portable conductivity meter. A plain-text line on the high-contrast LCD screen makes operation virtually self-explanatory. The meter stands out by the following features: • Use of digital Memosens sensors •...
Overview of the Portavo 902 COND Value-Added Features Memosens The Portavo 902 can communicate with Memosens sensors. These digital sensors are auto- matically identified and the meter switches to the appropriate measurement method. When a Memosens sensor is connected to the meter, it is indicated by the logo shown on the right.
Overview of the Portavo 902 COND Protective Cover The front of the meter is protected by a cover, which can be completely flipped over and secured to the back for oper- ation. A label on the inner side of the cover explains the control functions and device messages.
Overview of the Portavo 902 COND Display The meter has a three-line display for representing alphanumeric information such as measurement and calibration data, temperatures and date/time. Additional information is provided by means of icons (Sensoface, battery icon, etc.). Some typical displays are shown below:...
Overview of the Portavo 902 COND Keypad The keys of the membrane keypad have a noticeable pressure point. They have the following functions: on/off Switches the meter on and displays the device and calibration data (see Start-up) meas Switches the meter on /...
Start-Up Check the shipment for transport damage and completeness (see Package Contents). NOTICE! Do not operate the device when one of the following conditions applies: • the device shows visible damage • the device fails to perform the intended function •...
Start-Up Connecting a Sensor The Portavo 902 COND provides several connections so that many types of sensors can be used for measurement (see illustration below). Note that only one sensor may be connected to the meter at a time. The meter automatically recognizes a connected Memosens sensor and switches accordingly.
Start-Up Switching On the Meter When you have connected the sensor, you can switch the meter on by pressing the on/off or meas key. When the meter is switched on with the on/off key, first a self test is performed and then the calibration data and settings are displayed before the meter switches to measuring mode.
Configuring Conductivity Configuration Prior to measurement, a configuration should be performed to match the connected sensor and the desired measurement performance. Furthermore, you can select the suitable calibration method. The following table gives you an overview. Factory settings are shown in bold print. Measurement “Setup”...
Calibrating CELL CONST Calibration (Calibration by entry of cell constant) The calibration method is selected in the configuration menu. Measurement Calibration method, the number of calibration CELL CONST. points and the buffer set have been selected in the configuration menu. Value blinks to select the value for the cell constant.
Page 17
Calibrating 0.1 / 0.01 MOL KCL Calibration (Automatic calibration with KCl solution) The calibration method is selected in the configuration menu. NOTICE! • Make sure that the values of the calibration solutions used correspond exactly to those specified in this manual. If not, the resulting cell constant will be incorrect.
Page 18
Calibrating INST. FACTOR Calibration (For inductive conductivity measurement only: input of installation factor) Selected in the configuration menu. Measurement In narrow installation conditions, the conductivity measurement is influ- enced by the sensor’s distance to the wall and the wall material. This effect can be compensated for by the instal- lation factor.

Calibrating ZERO POINT Calibration (For inductive conductivity measurement only: calibrating the sensor zero point) Calibration method is selected in the configuration menu. Measurement Remove the sensor for calibration and place it in air – then start calibration. The “hourglass” icon blinks Calibration is performed.

Measuring Keys for Once you have completed all preparations, you can start with measurement the actual measurement. 1) Connect the desired sensor to the meter. Some sensors require a special preparation. Please proceed according to the operating instructions for the sensor. 2) Switch the meter on using the on/off or meas key.
Clock Press the clock key to access the clock mode. Date and time will be displayed in the format as set in the configuration menu. To set the clock, proceed as follows: Display of time+date Hour display blinks Set value. SET HOUR Minute display blinks Set value.
Options Enabling Options / TAN Input When you have bought “Option 002 Temperature Calibration”, you receive a document with a code (TAN) for enabling this option on your device. Press the set key to access the configuration mode. Use the arrow keys to select the “TAN TEMP CAL” function where you can enter the TAN for enabling the option.
Options Option 002 Temperature Calibration Selecting the temperature calibration (TEMP. OFFSET) In measuring mode, press the set key. 1) Select CAL (calibration) and confirm by pressing set. 2) Select the TEMP. OFFSET calibration mode and confirm by pressing set. Performing the temperature calibration (TEMP. OFFSET) In measuring mode, press the cal key.
