3.1
Prepare the electrode(s)
Rod Electrode
- Before filling, remove the cap with the wooden plug and soak it in water for about
an hour to allow the wood to saturate and swell.
Wheel Electrode
- The wooden plug is not intended to be removed. Immerse the wheel in water
well before you intend to use it to allow water to soak into the plug. The felt hoops and the felt hoop
connector should be saturated with water before measuring.
Copper Sulphate (Rod and Wheel)
- Prepare the saturated solution by mixing 40 units by weight
of copper sulphate with 100 units by weight of distilled water. In order to ensure that the solution
remains saturated, add an additional teaspoonful of copper sulphate crystals into the electrode.
The electrode should be filled as completely as possible with a minimum of air in the compart-
ment. This ensures that the solution is in contact with the wooden plug even when measuring in an
upwards direction.
Caution!
When handling copper sulphate be careful to take note of the safety
instructions on the packaging.
3.2
Connect the electrode / probe to the indicating device
Connect the half-cell electrode or Wenner Probe to the device as shown below:
Rod electrode connects to INPUT A and also
requires GND connection.
Wheel electrode connects to INPUT A, path
measurement connects to INPUT B.
GND connection is also required. (See 4.4)
Wenner probe connects to INTERFACE
RS232C only.
