  • Taking EC Measurements
  • Remove the protective cap.
  • Turn the EC meter on. The ON/OFF switch is located on the panel.
  • Immerse the meter into the water/solution up to the max. immersion level (2).

  • Wait until the display stabilizes. Once the reading stabilizes (approx. 10 seconds), press the HOLD button to view the reading out of the water.
  • If the meter displays a flashing x10 symbol, multiply the reading by 10.
  • After usage, shake off any excess water from your meter. Replace the cap.

  • Taking Temperature Measurements
  • Once the meter is on, the temperature function can be used at any time, in or out of liquid.
  • Press the TEMP button. The display will switch to temperature (in Celsius only).
  • To return to EC mode, press the TEMP button.

  • Changing the Batteries
  • Remove the battery compartment.
  • Install new batteries (model 357A). Be sure the batteries are properly aligned.
  • Replace the battery compartment. The meter will turn on automatically.
