Calibration of Standard Solution
Select the Standard Solution Calibration,
USA: 7.00, 4.01, 10.01
NIST: 6.86, 4.01, 9.18.
After the selection is completed, press the [ENT] button to enter the calibration mode
Submerse sensor into individual reference solutions different for 10 seconds min.
Note: begin with 7.00 USA - 6.86 NIST reference solution.
Press [ENT] button to calibrate.
The calibrated value will appear in box Move to next reference liquid and follow same procedure If the instrument has been calibrated, the
calibration screen will display DONE calibrated state. If recalibration is needed, press the [ent] key in this state to enter recalibration.
If the monitor prompts you to enter the calibration password, press or key to set the calibration safety password, then press
[ENT] to
confirm the calibration safety password.
Done
PH Calibration: After entering the calibration mode, the instrument displays as shown above. The instrument automatically identifies
the standard liquid, first calibrates the midpoint (example 7.00pH), then calibrates 4.01pH or 10.01pH. The corresponding mV value will be
displayed on the left side of the screen. After the calibration is completed, the offset and slope will be displayed on the right side of the
screen.The pH value of buffer solution was measured at 25°C.
To calibrate the instrument using an automatic identification buffer, you need a standard pH buffer that matches any of these values.
Before using automatic calibration, please select the correct buffer table (see “Buffer Table”).
Field Calibration — Select on-site calibration methods: [Linear calibration] , [Offset adjustment] , [linear adjustment] .
If only two points of calibration are needed, after two points of calibration, press the
[MENU] button to exit directly.
During the calibration process, Error prompt appears on the screen when the reference liquid is incorrect or sensor can not be calibrated.
(Replacement Sensor Required) The slope of glass electrode (> 0.90) is qualified.
