Saya ada DO meter YSI Pro 20 tombol On/Of tidak berfungsi kenapa ya?. Setelah Caliberasi succes, terus semua tombol macet. Bagaimana mengatasinya? Terimakasih.
Boleh cuba untuk ganti elektrolit ATAU membrane ATAU mengilapkan silver katod dan cuba kalibrasi semula. Pastikan meter sudah dihidupkan lebih kurang 10-15 minit sebelum mulakan kalibrasi. Jika gagal, berkemungkinan probe rosak.
Dear Devy, you have to make sure the meter is turn on within 10-15min before calibration is start. The condition of the sensor, have to keep it in moist sleeve during this waiting. One more thing, you have to make sure membrane in a good condition, and KCl already fill up in side the membrane and no air bubbles present. Hope, this is help. :)
