Plug the 12 VDC adapter into the power supply socket.
Connect the EC/TDS probe to the 7-pin connector. Make sure the probe sleeve is
properly inserted and tighten the threaded ring.
Turn the instrument on by pressing ON/OFF. All LCD tags are displayed and a beep is heard
while the instrument performs a self test.
The reference temperature is displayed on the LCD for a few seconds and the instrument
enters in the same range as it was at power off.

Make sure the instrument has been calibrated before taking conductivity measurements.
• Immerse the probe into the solution to be tested. The sleeve holes must be completely
submerged. Tap the probe repeatedly to remove any air bubbles that may be trapped
inside the sleeve.
• If necessary, press the RANGE/FIXED key until the display changes to EC mode.
• The conductivity value is displayed on the primary LCD and the temperature on the secondary
LCD, along with the reference temperature.
Notes Notes Notes Notes Notes:
•If the reading is out of range, the closest full-scale value (200.0 for MTC/ATC mode or 500.0
for uncompensated conductivity) will be displayed blinking.
•If SHIFT&FIXED keys are pressed to freeze the LCD range and the reading goes out of
range, the full-scale value of the frozen range will be displayed blinking.
The EC reading is affected by temperature. Three options for temperature compensation are
available in EC measurement mode.
