5.4.1.4. RNGE MODE DUAL: Dual Range Mode Configuration
DUAL range mode allows the A1 and A2 outputs to be configured with separate
reporting range spans as well as separate electronic signal levels. The analyzer software
calls these two ranges LOW and HI.
The LOW range setting corresponds with the analog output labeled A1 on the rear
panel of the instrument and is viewable via the test function RANGE1.
The HIGH range setting corresponds with the A2 output and is viewable via the test
function RANGE2.
While the software labels these two ranges as LOW and HI, when in DUAL mode
their upper limits need not conform to that convention. The upper span limit of the
LOW/RANGE1 can be a higher number than that of HI/RANGE2
To set the ranges press following button stroke sequence:
