• Press CAL when the instrument is in RELATIVE mV measurement mode.
The relative mV value and the temperature values are displayed.
• Use the ARROW keys if you want to change the displayed relative mV value.
• When the reading is stable, in mV range and the Relative mV offset is
inside the offset window (±2000 mV), CFM functional key is displayed.
• Press CFM to confirm relative mV calibration. The instrument will return to
measurement mode.
• If the absolute mV reading is out of range or the Relative mV offset is out
of the offset window, “Wrong relative offset” message is displayed.
Change the input value or the Relative mV value to complete the calibra-
tion process.
