4 OPERATION
4.3.2 Output Current
Enter the measuring range corresponding to the 4...20 mA output.E.g. -200 to 500 mV
corresponding to 4...20 mA. The beginning of the measuring range might be larger than the
end of it, e.g. -200 to 500 mV corresponds to 20...4 mA (inverted output signal).

RELAY
The sign can be changed like numbers.
The minimum measuring range is 0,5 redox. If the beginning of the measuring range equals
the end of it, there will be no display of the current value in the operation mode display

4.3.3 Relay
Definition of the relay functions. Two limit thresholds are set for each relay: 1- and 1+ or 2-
and 2+. Inversion of the relays and delay are available. A delay (0 to 180 seconds) pre-
vents the relays from being activated too fast, e.g. when time for homogenization is required
(e.g. measurements in tanks with agitator). If the redox potential exceeds a limit value, the
transmitter activates the relay at the end of the delay. Nothing happens, if the redox potential
passes again under the threshold before the delay is elapsed. Units and decimal points as
selected in the submenu "CURRENT" are active.
The following condition must be maintained 1- ≤ 1+ and ΔmV > 2.
