Instruction Manual Mi 306 EC/TDS Meter GENERAL DESCRIPTION Thank you for choosing Martini Instruments. This instruction manual will provide you the necessary information for correct use of the meter. Mi 306 is a waterproof portable logging microprocessor-based Conductivity/TDS/ NaCl/temperature meter. The autoranging feature of the EC and TDS ranges automatically sets the meter to the scale with the highest possible resolution.
www.milwaukeeinst.com PROBE MAINTENANCE Rinse the probe with clean water after measurements. If a more thorough cleaning is required, remove the probe sleeve and clean the probe with a cloth or a nonabrasive detergent. Make sure to reinsert the sleeve onto the probe properly and in the right direction. After cleaning the probe, recalibrate the instrument. SPECIFICATIONS Range EC (Autoranging) TDS (Autoranging) NaCl Temp. Resolution EC TDS NaCl Temp. 0.00 to 29.99 μS/cm 30.0 to 299.

www.milwaukeeinst.com SETUP Setup is used to view or change the instrument parameters. To enter setup press SHIFT+SETUP when the meter is in measurement mode. "Set" is displayed on the upper LCD. The lower LCD displays the blinking code of the current setup item. Select the desired setup item using the ▲ or ▼ key. Press SHIFT+CFM to confirm. Note: If SHIFT+SETUP are pressed before item confirmation, the meter will escape and return to measurement mode.
Instruction Manual Mi 306 EC/TDS Meter To change the value use the ▲ or ▼ key. Press SHIFT+CFM to confirm. Note: Press SHIFT+SETUP before confirmation to escape without changing the previously set value. The following table lists the setup items, their valid range of values and the factory settings (default): Item tc Description Temp. compensation coeff. Default 0.00 to 6.00 %/°C Valid value 1.90 tcE Temp.
www.milwaukeeinst.com 3 The battery charge level calculation is based on a typical alkaline battery discharge curve. If the meter is connected to an external power adapter and "Chr" is selected, the LCD will display "LINE". At startup, the main LCD shows briefly the reference temperature, while the secondary LCD shows "rEF". TAKING MEASUREMENTS Press the ON/OFF key to turn the meter on. At startup the display will show the reference temperature value with "rEF" indication for a few seconds.
Instruction Manual Mi 306 EC/TDS Meter 3 4 5 6 7 Make sure the meter is calibrated before taking measurements. If measurements are taken successively in different samples, to have accurate readings it is recommended to rinse the probe thoroughly with deionized water before immersion in the samples. To maximize battery life, the meter is automatically switched off after 5 minutes of non-use. To reactivate the instrument press the ON/OFF key.
www.milwaukeeinst.com The LCD will show the current reading together with a blinking "H" tag. When measurement becomes stable, the "H" symbol stops blinking and the measured value is frozen on the display. To exit this mode and return to normal operations, press again SHIFT+HOLD. Note: While in Auto Endpoint mode, current measurement (both stable and unstable) can be stored in the meter memory by pressing the MEM key.
Instruction Manual Mi 306 EC/TDS Meter If temperature compensation is active, measurements are compensated using a default temperature coefficient of 1.90 %/°C. It is possible to select a different temperature coefficient (TC) in the 0.00 to 6.00 %/°C range by entering the setup mode and selecting the "tc" item (see SETUP section for details). The current temperature coefficient can be quickly viewed pressing SHIFT+ATC. The value is briefly displayed on the lower LCD.
www.milwaukeeinst.com When the " " symbol stops blinking, the reading is stable. The "CFM" indication starts blinking on the LCD asking for confirmation. Press SHIFT+CFM to confirm the calibration. If everything is satisfactory, the meter displays the "Stor Good" message and returns to measurement mode. Notes I. The meter uses 1.90%/°C compensation factor during calibration.
Instruction Manual Mi 306 EC/TDS Meter LOGGING FUNCTION To store the current reading in memory press the MEM key while in measurement mode. The LCD will display "Stor" along with the "SAMPLE" indication and the sample number for a few seconds. By pressing the MEM key a complete set of information is memorized: date, time, EC/ TDS/NaCl and temperature readings. Up to 250 samples can be stored into memory.
www.milwaukeeinst.com • Press RANGE to view remaining data of the selected sample. After the date information, the remaining data will be displayed in the following order: year hour - EC, TDS, NaCL reading "----" means reading out of range or no probe was connected. - temperature reading "----" means reading out of range. • It is always possible to skip to another sample using the up and down arrow keys.
Instruction Manual Mi 306 EC/TDS Meter To delete logged data It is possible to delete a single sample or all the memory at one time. To delete a single sample: • Enter the viewing logged data mode and select the desired sample number. • Press SHIFT+HOLD. The "CFM" indication starts blinking asking for confirmation. • Press the SHIFT+CFM to confirm deletion. Note: Press SHIFT+HOLD to escape without data deletion.
www.milwaukeeinst.com DATA TRANSFER TO PC Connect the meter to a PC through the RS232C output (the connector is located on the top of the meter). Use MA 9351 9351(5 to 9 pin) connection cable. Specifications Isolated 8-bit data transmission Baud Rate: 2400 Start bit: 1 Stop bit: 1 Parity bit: none Sending Commands from PC With any terminal programs it is possible to remotely control the instrument.
Instruction Manual Mi 306 EC/TDS Meter BATTERY REPLACEMENT When the battery is low the meter will display the blinking battery symbol in the lower left corner of the LCD. When the battery indicator appears, the meter can still work for about 20 hours. A low battery condition will lead to unreliable readings. It is recommended to replace immediately the battery. Battery replacement must only take place in a non-hazardous area using a 9V alkaline battery.
