3. Complete Kit
4.Conductivity Calibration
4.1 Press key to switch to conductivity measurement mode. Rinse the probe in distilled water
and dry it.
4.2 Pour certain amount (about half volume of the calibration bottle) of 1413μS/cm and 12.88
mS/cm conductivity calibration solution into accordant calibration bottles.
4.3 Long press key to enter calibration mode, short press to exit.
4.4 Dip the probe in 1413 μS/cm conductivity calibration solution, stir gently and
allow it to stand still in the solution until a stable reading is reached. When stable
icon appears and stays on the LCD screen, short press key to complete one-point
calibration, the tester returns to measurement mode and indication icon will
appear at the bottom left of the LCD screen.
4.5 After calibration, dip the probe in 12.88 mS/cm conductivity calibration
solution. If the value is accurate, it is not necessary to conduct 2
nd
point
calibration. If it is inaccurate, follow the steps in 7.3 to 7.4 to complete the 2
nd
point of calibration
using 12.88 mS/cm buffer solution.
* 1000 µS/cm = 1 mS/cm
* 1000ppm = 1ppt
