pH Calibration
Bante900P portable meter allows up to 5 points calibration in the pH mode. We recommend that you perform at least 2 points calibration
for high accuracy measurement. The meter will automatically recognize and calibrate to following standard buffer values.
■
USA Standard Options: pH1.68, 4.01, 7.00, 10.01, 12.45
■
NIST Standard Options: pH1.68, 4.01, 6.86, 9.18, 12.45
■
DIN Standard Options: pH1.09, 4.65, 6.79, 9.23, 12.75
If you selected the user-defined option in the setup menu, the meter will allow only 2 points calibration. Single point calibration should only
be carried out with pH7.00, 6.86 or 6.79, otherwise calibration will not be accepted.
Make sure to calibrate the meter when attaching a new electrode or during first use. DO NOT reuse calibration solution after calibration,
contaminants in solution will affect the calibration and eventually the accuracy of the measurement.
SINGLE POINT CALIBRATION:
1.1 Make sure that you have selected 1 point calibration in the setup menu.
1.2 Rinse the pH electrode with distilled water.
1.3
Press CAL key, the meter shows “pH7.00/CAL” (or “6.86/CAL”, “6.79/CAL”).
1.4 Dip the pH electrode into the pH7.00 (or 6.86, or 6.79) buffer solution, the end of the electrode must be completely immersed into
the calibration solution. Stir the electrode gently to create a homogenous solution.
1.5
Press ENTER key, “Calibration” indicator begin
s flashing. Wait for the measured value to stabilize, the display shows
“END”
. The
meter returns to measurement mode automatically. Calibration is completed.
