Mode-
Selects display mode. Pressing this key changes the
display sequentially to display pH-AUTO, mV
(RmV)-AUTO, 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-AUTO mode, mV-AUTO 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.
