Operating Instructions Function selection 1) Turn on the meter by pressing the Power Button. To turn the meter off, hold the Power Button for over 2 seconds. 2) The meter has 3 measuring functions to choose from: Conductivity, TDS, and Salt. When the meter is on, press and hold the Function Button.
Zero Adjustment If the probe is not immersed in the measuring solution and the display will not show a Zero Value. Press and hold the Up Button for about 10 sec- onds and the display will then show zero. The Zero function is only valid for the 200µS range and not when the Zero Value is <...
5) Press the REC Button and HOLD Button at the same time. The display will show the symbol “Cd” and “CAL” 6) Press the Enter Button and the measuring value will show on both the upper and lower Display. Use the Up and Down Buttons to ad- just the upper display value to be the exact same as the standard conductivity value.
Backlight ON/OFF After powering the meter ON, the LCD Backlight will turn on automati- cally. While taking measurements, press the Backlight Button and the LCD Backlight will turn off. Press the Backlight Button once again to turn the LCD Backlight back ON. Datalogger Preparation Before Executing the Datalogger Function: 1) Insert the optional SD card into the SD card socket.
3) Stop Datalogging; while the Datalogger function is paused, press the REC Button for 2 seconds. The “REC” symbol will disappear indicating the Datalogging function has stopped. Manual Datalogger (Set sampling time = 0 seconds) 1) Set sampling time is to 0 second; Press the REC Button, and the “REC”...

Setting the Decimal point on the SD Card 1) When the lower display shows “dEC”, use the Up or Down Buttons to toggle between “bASIC” (“.” Decimal Point) or “Euro” (“,” Deci- mal Point). 2) After the Decimal point character has been selected, press the Enter Button to save the setting as the default.
Set sampling time 1) When the lower display shows “SP-t”, use the Up or Down Buttons to adjust the value. 2) After the Sampling value is selected, press the press the Enter Button to save the setting as the default. To exit “Advanced Settings”, press the Esc Button.
PC Serial Interface The instrument features an PC output via 3.5 mm terminal. The connector output is a 16 digit data stream which can be utilized to the user’s specific application. An USB RS232 lead with the following connection will be required to link the instrument with the PC serial input.
