• Menu index 3B2 Redox (ORP) FREQU OUT
“This menu is available on the pH–Redox System version”
The frequency output (Open collector circuit) can be used to control and guide the dosing of a remote
system in proportion to the Redox measurement.
• Menu index 3B3 Redox OUT Current Output
“This menu is available on the pH–Redox System version”
Note: The value set under the HOLD mA item is automatically generated by the instrument when a functional Hold
is present, for example due to a lack of water Flow Alarm or an enabled Voltage Input.
• Menu index 3B4 Redox ALARMS (level probe alarm only available on pH and Redox systems)
Note: The Holding Range and Holding Time items must be used together.
The indicated function controls the chemical measurement at a constant value for long periods of time.
This alarm can help to prevent incorrect dosing as a result of damaged probes.
