You can have the Q parameters be shown in the additional status
display in all operating modes (except for the

For each parameter type (Q, QL, QR, QS), define
the parameter numbers you wish to control.
Separate single Q parameters with a comma, and
connect sequential Q parameters with a hyphen,
e.g. 1,3,200-208. The input range per parameter
type is 132 characters.
The display in the QPARA tab always contains eight
decimal places. The result of Q1 = COS89.999 is
shown by the control as 0.00001745 for example.
Very large or very small values are displayed by
the control in exponential notation. The result of
Q1 = COS 89.999 * 0.001 is shown by the control as
+1.74532925e-08, whereby e-08 corresponds to the
factor of 10 -8 .
