Conductivity in the required engineering unit. If "0000" or "9999"
is displayed, input value is to low, respectively to high, change
unit or decimal point position
Temperature in °C or °F. If "---- ° C" or "---- ° F" is displayed,
temperature is out of range (-50...+150) or connection with Pt
1000 is interrupted.
The output signal 4...20 mA is proportional to the conductivity
according to the selected measuring range.
HOLD-function. If this function is activated, the transmitter
generates an output current corresponding to the last value before
the option was entered and the relays are blocked in their last
state. This allows the electrode to be cleaned without interruption
of the process. The display in the operation mode will flash and
there is no access to the parameter definition or the test menu,
while the HOLD-function is activated.
