• Press CAL when the instrument is in RELATIVE
mV measurement mode. The relative mV value
is displayed on the primary LCD and the absolute
mV value on the secondary LCD.
• 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” tag blinks.
• 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” tag will blink. Change the input value or
the Relative mV value on the primary LCD to complete the calibration
process.
