    PREPARATION Inserting the Batteries Four AAA batteries are included with your meter. Use a Philips screwdriver to remove the two screws holding the battery cover. See Figure 3 below. Lift meter stand to expose battery cover. Remove battery cover. Insert batteries. Follow the diagram inside the cover for correct polarity. Replace the battery cover into its original position using the two screws removed earlier.
  • Page 9 To connect the Conductivity/TDS electrode with built-in temperature sensor: During this operation, it is important that water does not get onto the BNC connector. Also avoid touching the connector with soiled hands. Slide the electrode connector of electrode over the socket of the meter (BNC connector). Ensure that the slot of the connector is inline with the protrusions of the socket.

  • Page 10: Attaching The Electrode Holder Onto The Meter

    Attaching the electrode holder onto the meter The meter has a slot on the side for the attachment of the electrode via the electrode holder. The meter provides a slot on the side of the instrument for the electrode holder. Hold the electrode holder over the slot of the meter.

  • Page 11: Attaching The Electrode Onto The Electrode Holder

    Attaching the electrode onto the electrode holder Your meter comes complete with an electrode holder. It is designed for easy use and installation.

  • Page 56: Additional Information

    11 ADDITIONAL INFORMATION What is Conductivity? In general, conductivity is a value that represents how easily electrical charges can be transported through a conductor. Conductors are substances that permit the movement of electrical charge with relative ease. Figure 39 shows a conductivity cell. It is an electrochemical cell for measuring the conductivity of an electrolyte solution.
