Data Hold Function And Backlight Display; Mode Button; Before You Send The Meter To Be Serviced - Sonel CMP-401 Manual De Uso

In the relative mode, the value shown on the LCD is always the
difference between the stored reference value and the present
reading. For example, if the reference value is 24,00V and the pre-
sent reading is 12,50V, the display will indicate -11,50V. If the new
reading is the same as the reference value, the display will be zero.
This feature also is made as DCA ZERO adjustment.
Press the REL button again to exit the relative mode.
