Close the meter case
1. Align the cables so that they are not pinched and do not obstruct the IR transmitter when the bottom case is
installed (Figure 1 on page 4).
2. Make sure the sealing gasket is installed in the groove of the top case.
3. Attach the bottom case and tighten the four screws evenly and securely. A waterproof seal cannot be
guaranteed unless the screws are tightened by hand and secure. Do not overtighten the screws.
4. Fill the pH/ORP sensor cup with pH storage solution and replace the protective cap.
Note: Always calibrate the meter after maintenance procedures.
