Setpoint setting
Press the SET click for after 3 seconds until the screen does not appear in "SET POINT" To change the value in the same time
click the button to decrease or increase the value. Note that the pH-value can be set is from 3,5 to 11 and the ORP from 300 mV to
900 mV
Calibration
Press for 5 seconds the CAL/OK bottun. The Calibration menu appears on the screen. You can look down the procedure of
the calibration for pH, please note that if calibration is for the redox measure there will be only one point calibration with the buffer
solution 650 mV. After calibration on the display will appear a life persentage of the probe, down 25% there will be a calibration
error, this means that the probe has to be replaced. PLEASE NOTE: Standard buffer solution for the pH measure are pH 7 and pH
9, there will be an calibration error if a buffer solution 4 pH is used.
PUSH CAL/OK for 5 seconds
INSERT PROBE IN BUFFER PH 7
MOVE IT
LET IT INSIDE AND DON'T TOUCH IT
CALIBRATING PH 7
7.20 PH (-90s)
1) WASH THE PROBE
2) INSERT PROBE IN BUFFER PH 9
3) MOVE IT
4) LET IT INSIDE AND DON'T TOUCH IT
CALIBRATING PH 9
9.20 PH (-90s)
QUALITY:
7.07 pH
NOTE: After calibrating the electrode with the solution pH 9 the instrument could show the alarm concentration error, this
alarm will disappear when the electrode is put into operation.
