Get some pH calibration solution 7.0 and make sure the meter is correct. The electrode has to be stored wet anyway. The good ones have a small screw driver with em to set it AND DIRECTIONS. Get some perlite and dolomite for the soil too.
Yes, i forgot, don't let the pen dry up. If you use it enough, just putting the cap back on will be enough, but if you let it dry up, it will go bad.
