Instruction Manual CyberScan pH5500/ 5000
Option: Connect the optional FET electrode by plugging it into
the FET jack on the back meter panel. Allow the FET electrode to
warm up five minutes before use.
Connect ion specific electrodes in the same manner as pH
electrodes.
If both a conventional and a FET electrode are connected to the
meter, do not put them in a solution together because you will get
inaccurate measurements.
Do not discard the BNC shorting cap.
3. Rinse and blot-dry (do not wipe)
electrodes between each
measurement.
Rinse electrodes
with distilled or deionized water,
or a portion of the next solution
to be measured.
4. Between measurements, store
conventional pH electrodes
storage solution, pH 4 buffer, or
KCI solution. Always leave the
filling hole of liquid filled
combination electrodes open.
Refill when the level of
solution gets below the
manufacturer’s recommended
level.
Proper electrode care is fundamental to obtaining reliable pH
measurements. Improper care of the electrode may cause the meter
reading to drift, respond slowly, or produce erroneous readings. For
this reason, the electrode should always be conditional and used in
accordance with manufacturer’s instructions.
