The MIN Alarm function selects a MINIMUM alarm level, after which the
alarm relay is triggered.
The MAX Alarm function selects a MAXIMUM alarm level, after which the
alarm relay is triggered.
The priming function blocks the setpoint value to allow the metering pump to
remain primed, the outputs are not active.

Refer to the SETPOINT 1 menu, as the SETPOINT 2 menu has the same settings as the SETPOINT 1 menu, with the exception of
the MIN/MAX ALARM function, indeed only found in the SETPOINT 1.

Calibration operations follow the type of parameter selected in the M e a s u r e m e n t T y p e paragraph
Press O K / M E N U to confirm the selection and go to the next sub-menu.
The Calibration menu shows the electrode to be calibrated according to the selected Measurement Type.
We suggest using new buffer solutions or still in good conditions (not old).
As for the lengths of the pH electrode cable we advise max 9 m: contact ETATRON for longer distances.
The mV value at the bottom of the screen shows the electrode’s efficiency (according to the manufacturer’s specifications)
pH CALIBRATION > BASIC MENU
* When Calibration starts, the display shows random values.
Dip the pH electrode in the buffer solution pH 7.00 for ZERO calibration, wait 2/3 minutes.
Press ◄► and ensure the display shows the value 7.00 pH, confirm with the OK/MENU button.
Rinse the electrode with water (possibly demineralised) and dab dry with a clean cloth or paper tissues.
Dip the pH electrode in the solution pH 4 or pH 9 for “Gain” calibration, wait 2/3 min.
Press ◄► until the display shows the value 4.00 pH or 9.00 pH, confirm with the OK/MENU button.

To have an accurate pH measurement, essential for the entire chemical-physical balance, it is recommended to perform periodic calibration
of the pH electrode
