PROGRAMMING THE LINEARIZER
To enter the Linearizer mode press the following key sequence:
CHA
->
DP
->
ENT
->
DP
Now the display shows:
LINEARIZER !!!
1=CL 2=AC 3=DEAC
By pressing the 1 key the Linearizer will be cleared. This means all error values are set to +12.7% and
all frequency points are set to zero.
By pressing the 2 key the Linearizer will be activated.
By pressing the 3 key the Linearizer will de deactivated.
Regardless of the key pressed the following display will come up:
LINEARIZER PROG?
0 = NO AND 1 = YES
If the 0 key is pressed the Linearizer selection done above will go into effect and the unit returns to the
regular operating screen.
If the 1 key is pressed the unit enters a 10-point programming routine. When the 10-point programming
routine is entered there is no short cut, which means, all of the errors and points have to be reviewed
and entered.
The following display will appear:
ERRxx=00000yy.y%
POIxx=zzzzz.zzHz
where,
xx is the current point 01 through 10
yy.y is the error -12.7% to +12.7% at point xx
zzzzz.zz is the frequency at which the error xx occurs.
There are 10 points to be programmed. The first thing to be entered is the percentage of error. To
change the sign use the DP key. After the correct percentage of error is put in the unit and the correct
sign is selected (+ or -) then press the ENT key. On the second line is the frequency at which the above
error occurs. Enter new frequency and press the ENT key. All ten points will show up, but only
program the points that are necessary. Leave all unused points at zero Hz.
The Linearizer uses linear interpolation between points, which means a straight line between two error
points.
** IMPORTANT ** The channel that will be linearized is the one on the display line 1 !!!!!
