PH500T pH Meter Operation Quick Guide
● Reading mode: supports continuous,
timing and auto reading mode.
The default is continuous reading mode,
you can choose according to your
requirements, press the "Enter" key to
complete the setting.

Calibration
1.
Setting.
1)
Set the parameters (e.g. pH).
2)
Select NIST standard solution
group, and check pH 4.01, pH
7.00 and pH 10.01 three
standard solutions.
3)
Set the Auto Mode recognition.
2.
After pressing the "Calibrate"-"pH
Verification" key, the instrument
enters the interface for selecting
calibration type. Select “Calibration”
to enter the pH electrode calibration
interface.
3.
Put the cleaned electrode into pH
4.01 standard solution. Wait for the
instrument to display “Auto Mode
Matched”, or the instrument reading
is stable, press "Start" to calibrate
1-point, after the completion of the
instrument, display calibration
results.
4.
If multi-point calibration is required,
please replace the pH7.01 and
pH10.01 standard buffer solutions.
After cleaning the electrode, put the
electrode into the standard solution.
After the instrument recognizes it
successfully, the instrument reads
stably, press the "Next Point" to
complete the calibration.
5.
During the calibration process, press
the “Enter” key to terminate the
calibration, and the instrument will
automatically display the window
prompts whether to save the
calibration results. After selecting,
directly enter the start interface.
interface. If the checked standard
solution group is 6, automatically end
the calibration after six points of
calibration.
3.3.
Measurement
1.
Setting.
1)
Set the parameters (e.g. pH).
2)
Set the reading mode (e.g.
continuous reading,
auto-reading, or timed format).
2.
Press " Measure" to enter the
measurement interface, after the
reading is stabilized (the data
stability mark is full), then measure.
3.
Press the "Save" to save the
measurement results. Press the
"Output" to print the measurement
result when connect to the printer.
Note: For accurate measurement, please
calibrate and measure at the same
temperature.
