5-4. Signal Adjustment
5-4-1. Signal Adjustment Preparations
Connect the display unit (BR series) or detector (BD series)
to the BS75A-R scale unit.
1 Remove the protective cap from the head connector of the
scale unit, and connect the head connector to the HEAD
IN terminal of the display unit or detector.
Note
• Never touch the connector pin with hands as this might
damage the inner electronic parts by the static electricity.
When the connector is not used, as for transport, be sure
to mount the protective cap.
• Be sure to switch off the power supply to the display unit
or detector before attaching or removing the connector.
2 Remove the cover of the signal adjustment section of the
display unit or the detector.
3 Connect the CH1 probe of the oscilloscope to S (SIN) and
G (GND).
4 Connect the CH2 probe of the oscilloscope to C (COS) and
G (GND).

5 Set the input coupling switches of CH1 and CH2 of the
oscilloscope to GND and adjust the oscilloscope to locate
the signal in the center of the screen.
6 Set the input coupling switches of CH1 and CH2 of the
oscilloscope to DC.
7 Set the TIME/DIV switch to the X-Y mode.
8 Set the deviation sensitivity (VOLTS/DIV) of CH1 and CH2
to 0.5 V/DIV.
9 Turn the display unit's or detector's power on.
