Input via the button group
The simplest method to input parameters directly and exactly is
•
via the button group (keyboard). The value selected will be
stored after pressing the appropriate button Hz, kHz, MHz.
Erasing values is possible by pushing [ESC]
the unit button. The formerly entered value will be restored. In
case an illegal value should be entered an acoustical signal will
sound (if this signal was activated), any formerly entered value
will remain valid.
In this example the value 102.56 kHz is to be entered:
Fr. 102.56_
-val+ <cur>
1 2 3 4
"Push the following buttons of the keyboard
[.], [5], [6]. Then push the button kHz/V, the display will show:
Fr: 102.5600000 kHz
-val+ <cur>
The cursor is now below the first digit to the right of the decimal
point.
Entering a parameter via the keyboard will always
cause the cursor to be placed below the first digit
to the right of the decimal point. The instrument did not need
to calculate,
In the following example the value 10256.78 Hz is to be entered:
STOP

"Push the following buttons of the keyboard in turn: [1], [0], [2],
[5], [6], [.], [7], [8]. Enter the number by pushing button Hz/mV.
The display will show":
Fr: 10.256780 kHz
-val+ <cur>
The instrument will change the value entered in Hz into kHz.
The cursor will not reside below the first digit to the right of the
decimal point.
However, if you now look at the Hz – display you
will notice that there was a 7 to the right of the
decimal point, the cursor will come below the same 7 in the
kHz – display.
