• Press CAL when the instrument is in RELATIVE mV measurement
mode. The “ mV” and “ ” tags will be displayed. Absolute mV is
displayed on the primary LCD and “ AbS” message is displayed on the
secondary LCD.
• When the absolute reading is stable and in measurement range, the
instrument asks for confirmation.
• If the reading is out of range, “ WRONG” tag will be displayed.
• Press CFM to confirm the absolute value. The instrument will display
“ 0.0 mV“ on the primary LCD and “rEL” message on the secondary
LCD. In this moment the relative mV offset is equal to absolute mV
reading.
• Use the ARROW keys if you want to change the displayed relative
mV value.
• Press CFM to confirm the relative mV value. The relative mV
offset is displayed on the primary LCD. The instrument returns to
measurement mode.
Note: The relative mV value can be changed only inside the relative mV
offset window (± 2000 mV).
