GENERAL ADJUSTMENTS
ADJUSTMENT PROCEDURE
Conditions: User control for geomagnetic compensation: 0
Geomagnetic compensation coil: Unconnected
Perform voltage measurement at both ends of RJ06 and adjust the volt-
age to the following adjustable value with GMF of data adjustment mode:
0

ADJUSTMENT PROCEDURE
Measure the terminal voltage waveform of test pin (DF terminal) with 100:1 probe and
adjust the terminal voltage using L451 (horizontal amplitude coil: TLN2110AD).
Adjust the above waveform by turning the core of L451 so as to obtain the following
voltage:
34": 1000 Vp-p
Note: Because the vertical cycle parabolic waveform is also of superposition, the
above voltage value shall be measured on the waveform.
Adopted signal: PAL E-12ch
