• HM Digital EC-3 Handheld Conductivity Tester Instructions:

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”).
• Lightly stir the meter to dislodge any air bubbles.
• 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.

Precautions
• The meter is not water-tight. Do not dip the meter beyond the water level limit. The warranty will be voided if water enters the unit.
• Do not store the meter in high temperatures or direct sunlight. Damage to the unit caused by user error or carelessness will void the warranty.
• Do not attempt to open the housing or tinker with the electronics of the unit. Any unauthorized work on the unit will void the warranty.
• Though durable, the EC-3 is an electronic instrument and should be treated with proper care and maintenance.
