mV Output Measurement Mode (pH Electrode)
Note:
The millivolt capability of pH meters can be used to
determine the actual slope of pH electrodes but it is mostly
used to measure the voltage potential difference.
1.
Connect the included pH Electrode into the Input (BNC) Jack.
2.
Press the
button to select ORP mode.
3.
Place the electrode into the measured solution, so that the tip of the
electrode and junction are fully immersed and stir at a moderate,
uniform rate.
4.
The LCD will display the pH electrode output in mV.
ORP Measurement Mode
(Optional R3525-ELECTRODE2 required)
1.
Connect the ORP Electrode into the Input (BNC) Jack.
2.
Press the
button to select mV (ORP) mode.
3.
Place the electrode into the measured solution, so that the tip of the
electrode and junction are fully immersed and stir at a moderate,
uniform rate.
4.
The LCD will display the mV.
Over Range
When the pH value is under or over the meter's measuring range, the
LCD display will indicate "- - - -". If the electrode is not placed in any
solution or connected to the meter, the LCD display will also indicate "- - - -".
pH Calibration Procedure
In order to obtain the most accurate results possible,
a pH meter should be calibrated at least once a day.
If the pH meter is stored for an extended period of time, prior to calibration,
condition your electrode in pH 4 buffer solution or distilled water for a
minimum of 1 hour.
