CAL-
This will be displayed when the
unit enters into the calibration
mode.
10.
MAIN DISPLAY-
For Conductivity, Salinity and
TDS values.
5.
AUTO-
Auto ranging indicator
11.
SECONDARY DISPLAY-
For temperature in
℃
.

ATC indicator will be displayed
if a temperature probe is
connected otherwise the MAN
indicator will be displayed.

Mode-
Selects display mode. Pressing this key changes the
display sequentially to display pH-AUTOLOCK, mV
(RmV)-AUTOLOCK, pH , mV (RmV) , Conductivity ,
Salinity and TDS . The calibration values will not be
affected by changing the display modes. In
“calibration”,
press
“Mode”
key to exit calibration
mode.

Clear-
It is used to clear the unit when error signal appears. It
clears all calibration values stored in the internal
memory.
Under normal use the key will not be activated unless
pressed and held for 5 seconds to prevent accidental
erasing stored memory.
In pH, mV (Rmv) or conductivity (salinity, TDS) mode,
when the
“Clear”
key is pressed for 5 seconds, all
segments of the LCD will be lit on.
After 2 seconds the
unit
will
enter
the
pH-AUTOLOCK
mode,
mV-AUTOLOCK mode or conductivity mode, In the
pH mode, the “AUTO” and “CAL” icons will be
displayed and one of the buffer values in the
pre-selected buffer set will begin to flash. This means
that the unit is un-calibrated and requires new pH
calibration before use. In the ORP mode, the “AUTO”
and “mV” icons will be displayed. This means that the
unit is un-calibrated and requires new ORP
calibration before use. In the conductivity mode, the
“AUTO” icon will be displayed. This means that the
unit is requires new conductivity calibration before
use.
