Hi, Could you do a video showing how to calibrate the Primo 5 (μS) EC and TDS tester... I just bought one. Thanks.

Hi Cury. The calibration of this tester is pretty simple.
• Switch the meter on.
• Press and hold the ON/OFF button for about 3 seconds.
The required calibration solution value will start blinking
on the display to indicate that the calibration mode has
been entered.
“1382” for Primo, Primo 1, Primo2, Primo3
“5.00” for Primo 4, and “1413” for Primo 5
• Immerse the probe in the proper calibration solution
without exceeding the maximum immersion level.
• Stir gently and wait for about 20 seconds.
• Once the display stops blinking, the meter is calibrated
and ready for use.
