Conductivity Module
1.
Connect a conductivity probe to the 8 pin MiniDIN connector on the module. If the
conductivity probe has a built-in temperature probe, the temperature will also be measured
when the conductivity probe is connected.
2.
Prepare the conductivity probe for use as instructed in the probe user manual.

Conductivity Measurement Module
Channel 1-4 Setup Menus
Mode Menus for Conductivity, TDS, Salinity and Resistivity
Within the Channel 1, Channel 2, Channel 3 and Channel 4 setup menus are Method, Mode
and Temperature submenus, which can be used to customize measurement settings and
parameters for the selected channel. This section provides detailed information on the Mode
menus for each measurement parameter available when using a conductivity module.
1.
In the measurement mode, press the setup key.
2.
Press the ◄ or ► key to highlight Channel 1, Channel 2, Channel 3 or Channel 4 (channel
number the module is connected with) and press the f3 (Select) key.
3.
Press the ◄ or ► key to highlight Mode and press the f3 (Select) key.
4.
Press the ▲ or ▼ key to highlight Conductivity, TDS, Salinity or Resistivity and press the
f3 (Select) key.
5.
Press the ▲ or ▼ key to highlight a menu option and press the ◄ or ► key to highlight a
submenu option. Onscreen text prompts provide instructions for changing the parameters.
a.
Use the popup keypad screen
for
Electrode SI No and
Sample ID. Press the
▲, ▼, ◄ or ► key to highlight
an alphanumeric character (numeric only for
Auto
Increment Sample ID), p
ress the f2 (Enter) key to input
the character and repeat until the desired label is
entered. Press the f1 (Done) key to save the entry.
