Relative mV 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 dis-
played 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.
