Fundamentals | Status displays
Display of Q parameters (QPARA tab)
Soft key Meaning
Display the current values of the defined
Q parameters
Display the character strings of the defined string
parameters
Press the Q PARAMETER LIST soft key. The control
opens a pop-up window. For each parameter type (Q,
QL, QR, QS), define the parameter numbers you wish to
check. Separate single Q parameters with commas and
connect sequential Q parameters with a hyphen (e.g.,
1,3,200-208). The maximum number of characters per
parameter type is 132.
The display in the QPARA tab always contains eight
decimal places. The result of Q1 = COS 89.999 is shown
by the control as 0.00001745, for example. Very large
and 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
The display of QS parameters is restricted to the first 30
characters, i.e. the contents might be truncated.
