1.Remove the protective cap.Turn on the meter.
2.First rinse the electrode with distiled water,and suck it with fiter-paper
3.immerse the electrode in the solution to be tested.
4.Sr gently and wait for the reading to stabilize.Do not tap it against the glass.
5.Short press the”MODE”burton,choice the PH or EC(TDS)for measuring.
6.in the EC(TDS)MODE,Long press the “MODE”button(about 5 seconds)to
smach the display of EC value and TDS value on the screen successively(
7.After use,turn off the meter.Rinse the electrode with distiled water to
8.Always replace the protective cap after use.
9.Switching Temperature Modes
Shot press the TEMP/CAL’button to switch between Celsius and Fahrenheit
For a single-point calibration
Pour a small quantity of pH6.86,pH4.01 and pH9.18 solution into clean beakers
2.For a particularly accurate calibration,it is advised to use wo beakers
for each buffer soluion, one for rinsing the eledrode.ong for the
Calibration In this way.the risks of contaminatng the butler solution are reduced to a minimum.
3.Turn on the meter.Press the “MODE”button,choice the PH for
4.lmmerse the electrode in a pH 6.86 buffer solution,and gently shake it until the reading to stabilize.
5.Press and hold the ‘TEMP/CAL’button about 5 seconds until 686 appears on the display.Release the button.The LCD will display “6.86”.Rinse the electrode with distilled water.
6.lmmerse the electrode in a pH 4.01 bufer solution,and gently shake it until the reading to stabilize.
7.Press and hold the”TEMP/CAL’button about 5 seconds until 400 appears on the display.Release the button.The LCD will display”4.01″.Rinse the electrode with distilled water.
8.Immerse the electrode in a PH9.18 buffer solution,gently shake the
electrode and waiting for the reading to stabilize.The showing value and buffer solution’s ph value is within eror range.
The calibration of the instrument’s pH range is now complete.
Note: It is always recommended to carry out a two point calibration for better accuracy.
