OPERATOR'S CHECKS AND ADJUSTMENTS
INTRODUCTION TRACE ROTATION
To verify the operation and accuracy o f your instru­
ment, perform the following check and adjustment pro­
cedures before making a measurement. If adjustments are
required beyond the scope o f these operator's checks
and adjustments, refer the instrument to a qualified service
technician for calibration. Before proceeding w ith these
instructions, verify that the LINE VOLTAGE SELECTOR
switch is placed in the proper position and that the correct
line fuse is installed for the ac-power-in put source voltage
to be used. Refer to the "Preparation fo r Use" information
in this manual for procedures relating to ac-power-in put
source voltage and fuse selection. Verify that the POWER
switch is OFF (push button out), then plug the power cord
into the ac-power-input source outlet. Push in the POWER
switch (ON) to apply power to the instrument and allow
sufficient time for warm-up before starting these checks
and adjustments. Warm-up time required to meet all the
instrument's specification is 20 minutes.
1. Preset instrument controls and obtain a Normal
Sweep Display (refer to "Instrum ent Fam iliarization").
2. Use the Channel 1 POSITION control to move the
baseline trace to the center horizontal graticule line.
NOTE
Normally, the resulting trace w ill be parallel to the
center horizontal graticule line, and the Trace
Rotation adjustment should n o t be required.
3. If the resulting trace is not parallel to the center
horizontal graticule line, use a small-bladed screwdriver to
adjust the TRACE ROTATION control (see Figure 3)
and align the trace w ith the center horizontal graticule line.
