PRELIMINARY PROCEDURE FOR
ADJUSTMENT
NOTE
The oscilloscope must be adjusted within an am­
bient temperature range of +20° C to +30° C for best
overall accuracy and to meet the electrical
characteristic tolerances given as Performance Re­
quirements in the Specification section of this
manual. Information given as Supplemental Infor­
mation in the Specification section is provided for
user information only, and should not be interpreted
as Performance Requirements.
1. Remove the cabinet sides and bottom from the
oscilloscope (refer to Cabinet Removal in the
Maintenance section of this manual).
2. Check the rear panel of the oscilloscope to ensure
that the indicated line voltage and the line voltage source
are
the same (refer to Operating Voltage in the
Maintenance section of this manual).
3. Ensure that all test equipment is suitably adapted to
the line voltage to be applied.
4. If applicable, install the TM 500-series test equip­
ment into the test equipment power module.
5. Install a vertical amplifier unit into the left vertical
compartment of the oscilloscope.
6. Install a time-base unit into the horizontal compart­
ment of the oscilloscope.
7. Connect the equipment under test and the test
equipment to a suitable line voltage source. Turn all
equipment on and allow at least 20 minutes for the
equipment to stabilize.
NOTE
Titles for external controls of the oscilloscope are
capitalized in this procedure (e.g. INTENSITY,
POWER). Internal adjustments are initial capitalized
only (e.g. Intensity Range, Vertical Gain).
