Relative mV Relative mV Relative mV Relative mV Relative mV MEASUREMENTS MEASUREMENTS MEASUREMENTS MEASUREMENTS MEASUREMENTS
To measure the Relative mV of a sample:
• Press and then to enter Relative mV
Measure mode.
• The instrument will display the measured Relative mV value
on the LCD, together with a short GLP information about the
last calibration or “Not Calibrated” message if no Rel mV
calibration was performed (no Rel mV offset set).
Notes: • If the measured mV potential is out of range, “-----”
will be displayed on the LCD.
• If pressing while in Relative mV Measure
mode, the Relative mV offset screen will be displayed
on the LCD. Press
to clear the existing
Relative mV or use or to adjust
the Relative mV value and then press to save
the current Relative mV. Press at any time
to return to Relative mV Measure mode.
• Before performing a Rel mV calibration, make sure
that the electrode is immersed into the sample to be
measured.
