=
2 2
or
r r..1 1
=

(2 or 3 point calibration).
3. Press /pH to select the
desired calibration type.
4. Press T/mV to display

Connect the pH Electrode
1. Secure the pH electrode to the pH input BNC
connector on the back of the controller.
2. If you are using automatic temperature
compensation (ATC), connect the RTD as shown
below.
Apply Power
1. Apply ac power to the unit.
The unit initializes, flashing the following
messages:
r rs st t
,
p ph h
,
i in ni it t
. Then a pH value
appears.
2. Verify that a value appears. If not:
• Remove ac power.
• Verify the TB1 power connections.
• Check your power source.
• Apply ac power again.
