” key to select the parameter (pH or mV)
which you want to clear before entering setup mode.
While in setup mode, press “

P3.0 Electrode-for pH probe only (ELE)
To view the pH electrode data (slope & offset value) from WT-80:
Press “
MODE
” key to select the mode as pH before entering setting mode.
Press “
p
“ to select P3.0 while in setting mode, “
ELE
“ appears on the LCD.
Press “
ENTER
” key to enter P3.1, LCD displays 1of 4 available slope values
(P3.1 to P3.4). If the value is <75% or >115%, suggest to change electrode
immediately.
Press “
ENTER
” key to review P3.2, P3.3 & P3.4 (Fig. 7)
Press “
ENTER
” to enter P3.5 to view the offset value.(Fig. 8) Offset value is the
mV value of pH 7 and the default offset value is 0.0. The offset value will be
different after re-calibration. When the offset value is out of range +60mV,
strongly suggest you to replace with a new probe.
