It indicates, from left to right:
4.
In models HD2205.2 and HD2256.2 : The symbol indicates the quality of the pH electrode con-
nected to the inputs
c
or
e
, or the CAL blinking message if the probe connected to the pH
input is not calibrated. The symbol shows an electrode that gets “empty” as its efficiency de-
creases.
In the
HD2206.2 instrument, the cell constant value of the conductivity probe connected to in-
puts
i
or
j
. It has up to 4 different calibration points and nominal cell constant corrections.
The displayed value is referred to the calibration point at 1413
μ
S/cm .
5. In the HD2205.2 instrument, the symbol indicates the quality of the pH electrode connected to
the inputs
d
or
f
, or the CAL blinking message if the probe connected to the pH input is not
calibrated.
In the
HD2206.2 instrument, the temperature coefficient

In the HD2256.2 instrument, the cell constant value of the conductivity probe connected to in-

. It has up to 4 different calibration points and nominal cell constant corrections.
The displayed value is referred to the calibration point at 1413

6. The EPT (End PoinT) symbol indicates the display mode. The mode selection is done using the
ENDPNT function key ( SHIFT/FNC key >> F4 key). When EPT is blinking, the measurement
is updated on the display; when it is fixed, the measurement is “frozen”. For a new measurement,
press F3 = MEAS.
EPT = DIR : The instrument operates in continuous view mode . In this mode the displayed
measurement is updated every second (standard mode).
EPT = MAN : The displayed measurement is continuously updated until F3 = MEAS is
pressed. During the measurement update, the EPT-MAN symbol is blinking. For a new
measurement, press MEAS.
EPT = TIME : The measurement is frozen after a set time of 8 seconds. For a new measure-
ment, press MEAS.
EPT = AUTO : The instrument performs the measurement, and when it stabilizes the EPT-
AUTO symbol stops blinking. For a new measurement, press MEAS.
