ADJUSTMENT

To obtain the best performance, periodically calibrate the
unit. Sometimes, only one mode need be calibrated, while
at other times, all modes should be calibrated. When one
mode is calibrated, it must be noted that the other modes
may be affected. When calibrating all modes, perform the
calibration in the specified sequence.

The following calibration required an accurate measuring in-
strument and an insulated adjusting flat blade screwdriver.
If they are not available, contact your dealer. For optimum
adjustment, turn the power on and warm up the scope suffi-
ciently (more than 30 minutes) before starting.

Before calibrating the scope, check the power supply
voltage.

om VR (TC) P.c.B. Procedure

Supply voltage VR1 X68-1570 Adjust VR1 to give—8,00 V at pin P1-6.

Intensity VR2 X68-1570 MODE: X-Y
With a spot on the screen, turn the INTENSITY knob to a 9 o'clock posi~
tion and then adjust VR2 until the spot disappears.

CRT center VRIOZ X65-1380 CH2: 50 mV/DIV. GND
VvMODE: CH2
Pull and push INV to find a position of POSITION knob where the lumines-
cent line does not vary.
Leaving POSITION unchanged, adjust to the center of the screen using
VR102.

Y operating point VR104 X65-1380 Position after CRT center adjustment
Adjust VR104 to give + 57.0 V at pin P64.

X operating point VR301 X65—1380 MODE: X-Y

FOCUS: 12 o’clock
CH1,2: 50 mV/DIV, GND
Adjust the spot ”.' to the best position with the ASTIG knob and VR3.

CH1 Step VR2 X65-1380 CH1: GND

ATT Balance Adjust VR2 so that the luminescent line does not vary when switching
between 1 mV/DIV and 2 mV/DIV.

Adjust VR3 so that the luminescent line does not vary when switching
between 2 mV/DIV and 5 mV/DIV.

CH2 Step VRSZ X65-1380 V-MODE: CH2

ATT Balance CH2: GND
Adjust VR52 so that the luminescent line does not very when switching
between 1 mV/DIV and 2 mV/DIV.

CH2 MAG Balance VR53 X65-138O V-MODE: CH2

Adjust VR53 so that the luminescent line does not vary when switching
between 2 mV/DIV and 5 mV/DIV.

ADD Position VR101 X65-1380 CH'I,2: GND
Bring the luminescent line to the center for both CH1 and CH2. Switch
V-MODE to ADD and adjust VR101 so that the luminescent line comes to
the center.
