7. Press
CAL
for more than 2 seconds to
begin calibration. The conductivity value
of the solution will flash on the LCD.
8. Press ▲ or ▼ to adjust the value on
the primary display to match the value
of the standard buffer. You can adjust
the conductivity reading ± 30% from the
detected value. If the detected value
and the standard value differ by more
than ± 30%, clean or replace the pen.
Example:
Standard: 10 µS; Detected value: 19 uS
Adjustable range: ± 5.7 µS (19*30%)
Under the above situation, the values
differ by over 30%.
Note…
If the standard value is over the measuring
range or 10% less, the displayed value will
be equal to the range limit or 10% of the
range limit.
Example 1:
Standard: 22 µS; Detected value: 19 µS
Adjustable range: ± 5.7 µS (19*30%)
