Voltage
Voltages can be measured in the following
basic ranges:
Basic ranges
–15 +77 mV
0 +170 mV
–76 +76 mV
–162 +880 mV
0 +1930 mV
–880 +880 mV
–1.84 +10 V
0 +22 V
–10 +10 V
shortest span: 5 mV
Within these basic range limits the start and
end of range can be freely programmed, up
to 999 mV in 0.01mV steps, from 1V in 1mV
steps.

Customized linearisation
In the setup program there is a choice be-
tween linear, square law and cube law line-
arisation. There can be up to 41 calibration
points for linear and square law linearisation,
and up to 61 calibration points for cube law
linearisation. These calibration points are
used to determine the coefficients for poly-
nomials defined for each section so that
even a few calibration points produce a
smooth graph.
