Connect the digital tester to the 5V-S and GND-S check pins and adjust VR3 so that the voltage is 5.0V.
Connect the digital tester to the 12V and GND-S check pins and verify the voltage is 12.0±0.6V.
Connect the oscilloscope to the FRQ and GND-P check pins and adjust the waveforms at VR1 so that the below
is shown.
The value of frequency counter is 56.0 kHz.
17.85μsec(56.0 kHz)
Verify the voltage bVOUT and -VOUT (GND-S) in the Power Supply PCB No.694 is 12.0.0V, +0.46V, -
0.26V.
-30-
Adjust the Power Supply PCB (No.692) for S-1800M15 (MBB)
(Reckless adjustment may cause serious problem.)
Confirming the voltage on the Power Supply PCB (No.694) for S-1800M15 (MBB)
