The ” pH 4.01 USE ” message is then displayed. Place the
probe in the second calibration buffer (pH 4.01 or 10.01).
When the second buffer is accepted, the LCD will display
“
SAVE ” for 1 second and the meter will return to the normal
measurement mode.
If the buffer is not recognized or the slope is out of accepted
range ”
--- WRONG ” is displayed. Change the buffer, clean
the electrode or press any key to exit calibration.
It is always recommended to carry out a two‑point calibration
for better accuracy.
When the calibration procedure is completed, the
tag
is turned on together with the calibrated points.
To exit calibration and reset default values
After entering the calibration mode and before the first point is
accepted, it is possible to quit the procedure and return to the
last calibration data by pressing the button. The LCD displays
“
ESC “ for 1 second and the meter returns to normal mode.
To reset the default values and clear a previous calibration,
press the
SET button after entering the calibration mode
and before the first point is accepted.
The LCD displays “
CLEAR “ for 1 second, the meter resets to
the default calibration and the tag with the calibrated
points on the LCD disappears.
QUICK CALIBRATION FOR pH AND EC
Select calibration type “ QUICK “ from meter setup. Enter
calibration mode. Immerse the probe in the HI50036
calibration solution. When the standard value is recognized
and stability is reached the meter automatically accepts the
calibration. The LCD will display “
SAVE ” for 1 second and
return to normal measurement mode. If the standard is not
recognized or the slope is out of accepted range “
--- WRONG “
is displayed. Change the calibration solution, clean the electrode or
press any key to exit calibration. When the calibration procedure
is completed, the
and tag is turned on.
pH ELECTRODE CONDITION
The display is provided with a probe icon (unless the feature
is disabled from setup) which indicates the pH electrode
status after calibration. The “condition” remains active for
