1.
WAIT-
This will be displayed when
the unit is still waiting for a
stable reading or end point
sensing.
7.
AUTO-
AUTOLOCK mode
indicator.
2.
BAT-
Low battery indicator.
8.
Buffer selection-
This indicator will flash if the
unit is not yet calibrated.
This indicator will remain
lit-up if the unit has been
calibrated.
3.
pH-
Unit and mode indicators.
9.
LOCK-
This will indicate that the
reading is frozen during
AUTOLOCK mode.
4.
mV (RmV)-
Unit and mode indicators.
10.
EFF-
This will be displayed when
the user is viewing the
efficiency of the electrode.It
is recommended to use a
new electrode when the
efficiency value is less over
than 75%.
5.
ATC/MAN-
ATC indicator will be
displayed if a temperature
probe is connected
otherwise the MAN indicator
will be displayed.
