FLASHING RED
Red LED. It indicates an ALARM status.
FLASHING RED
RED
Red LED. It indicates a status of total stoppage of the functions of the instrument.
RED
When this LED is illuminated, it signals a temporary block of operation of the pumps. The current
outputs remain locked on the last value that was re-transmitted.
CALIBRATION FUNCTIONS
7 pH
4 pH
465 mv
The pH pump is OFF.
The set point is active but the pump is temporarily OFF.
The set point is active and the pump is ON.
During programming it indicates that the parameter being
displayed refers to control of the pH set point.
The chlorine pump is OFF.
The set point is active but the pump is temporarily OFF.
The set point is active and the pump is ON.
During programming it indicates that the parameter being
displayed refers to control of the Redox set point.
An alarm status has occurred. The alarm relay has been
activated. To reset the alarm press the ACK key.
An alarm has been acknowledged by pressing the ACK
key, however the cause that generated the alarm is still
present. Once the cause is removed the alarm LED will
extinguish.
The instrument is prompting you to dip the electrode into a
sample solution a 7 pH it is therefore ready to carry out
calibration of the offset on the pH electrode.
The instrument is prompting you to dip the electrode into a
sample solution with a pH of 4. It is therefore ready to
carry out calibration of the gain on the pH electrode.
The instrument is prompting you to dip the electrode into a
sample solution at 465 mV. It is therefore ready to carry out
calibration of the gain on the Redox electrode.
