To prevent improper operationof systems or pumps that are controlled directly by the current output, place the analyzer in holdbefore removing the sensor for calibration and maintenance. Be sure to remove the transmitterfrom hold once calibration is complete. During hold, both outputs remain at the last value. Oncein hold, all current outputs remain on Hold indefinitely.44 Transmitter Programming
