relay output is not operational in this mode. See section 3.5.
2.
STANDBY

to inhibit the Alarm LED and (optional)
output relay action. Select this mode for calibration, or when
automatic dosing is not required.

relay output. These will be activated when the Redox is
outside the limit value. See section 3.5.
4.

to manually dose chemicals when the
optional relay output is fitted. The relay output will be
activated for as long as the
