pH Module
1.
Connect a pH electrode or ORP electrode to the BNC connector on the module.
2.
Connect an ATC temperature probe to the 8 pin MiniDIN connector on the module.
3.
Connect a reference half-cell electrode to the pin tip connector on the module (for use when
a half-cell sensing electrode with BNC connector is used).
4.
Prepare the electrodes for use as instructed in the electrode user manuals.

pH/ISE Module
1.
Connect an ion selective electrode (ISE), pH electrode or ORP electrode to the BNC
connector on the module.
2.
Connect an ATC temperature probe to the 8 pin MiniDIN connector on the module.
3.
Connect a reference half-cell electrode to the pin tip connector on the module (for use when
a half-cell sensing electrode with BNC connector is used).
4.
Prepare the electrodes for use as instructed in the electrode user manuals.

pH/LogR Module
1.
Connect a pH electrode or ORP electrode to the BNC connector on the module. LogR
technology allows the temperature to be measured using the glass bulb of a pH electrode.
2.
Connect an ATC temperature probe to the 8 pin MiniDIN connector on the module.
3.
Connect a reference half-cell electrode to the pin tip connector on the module (for use when
a half-cell sensing electrode with BNC connector is used).
4.
Prepare the electrodes for use as instructed in the electrode user manuals.

pH, pH/ISE and pH/LogR Measurement Modules
Channel 1-4 Setup Menus
Mode Menus for pH, mV, Relative mV, ORP and ISE
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. When using a pH/ISE module that is set to the ISE
measurement mode, an Incremental Techniques submenu is also available. This section
provides detailed information on the Mode menus for each measurement parameter available
when using a pH, pH/ISE or pH/LogR 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 pH, mV, Relative mV, ORP or ISE
(pH/ISE module only)
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.
