Voltage
Voltages can be measured in the following
basic ranges:
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.

Current
Currents can be measured in the following
basic ranges:
shortest span: 0.5 mA
Within these basic range limits the start and
end of range can be freely programmed in
0.01mA 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.
Accuracy: depends on shape of graph

0 mA is recognised.
In case of a break at the transducer all pens
are positioned on 0 %. The LED dot matrix
