2 Press to select DC voltage measurement in primary display.
3 Press to select AC voltage measurement for secondary display.
4 Press . Use and to select autoranging or manual range for
secondary display.
NOTE
– Press to disable the secondary display.
– Press to select the suitable range if DCV+ACV ripple is above the scale
of the current range.
