"ERROR" on the display (except in electrode calibration function) indicates that calibration
data are lost. By pressing ENTER, the user can access the main menu but the transmitter
works with the factory settings (see §5.4). The transmitter needs re-calibration. If this mes-
sage recurs, please return the transmitter to your supplier.
Transmitter, separate version:
Temperature: If "----°C" or "----° F" is displayed, temperature is out of range (T < -33 °C or
T > +140 °C) or connection with Pt1000 is interrupted. In this case "PH = --" is displayed.
For the outputs (current and relays) pH=0 is fixed.
pH values out of range: pH>14 or pH<0, "PH = --" is displayed. For the outputs (current
and relays) pH=14, respectively pH=0, are fixed.
Electrode voltage: >+575 mV or <-575 mV. "PH = --" and "---- mV" are displayed. For the
outputs (current and relays) pH=0, respectively pH=14, are fixed.
Power failure: In case of power failure, the display turns off, 4-20 mA and pulse output to 0,
alarm relays open. When the power supply is turned on, the transmitter is set to the pre-
vious configuration and to operation resumes.
