This feature is not usually used.
Perform span adjustment during calibration, when you wish to precisely realign the span
(recording paper width) to compensate for the expansion and contraction of the recording
paper, or when you wish to vary the span for other reasons.
The recording width can be adjusted with a precision slotted screwdriver.
As shown below, the chart cover can be opened up to the line indicated by the label.
Do not attempt to push the chart cover beyond the line as doing so may damage it.
SPAN (span adjustment)
• To increase the width: Turn clockwise.
(The recording width can be increased up to 20%.)
• To decrease the width: Turn counterclockwise.
(The recording width can be decreased up to 20%.)
Adjusting the span causes values to diverge from the calibrated values guaranteed by HIOKI.
After making measurements following span adjustment, have HIOKI or your nearest distribu-
tor recalibrate the instrument.

Be sure to read "Operating Precautions" (p. 5) before using the instrument.
2.2 Loading Recording Paper
14
You can use either fanfold or roll type recording paper in the instrument.
See: "Options" (p. 2)
2.2 Loading Recording Paper
• Please use only the specified recording paper. Using non-specified paper may not only
result in faulty printing, but printing may become impossible.
• If not loaded properly, recording paper may jam.
• Do not use wet recording paper. Doing so may damage the instrument.
• Do not reuse recording paper. Doing so may prevent the paper from feeding properly.
• Store recording paper at room temperature, taking care to avoid high temperatures and
humidity. Avoid moisture (rain or condensation).
Loading Fanfold Recording Paper
1 Turn on the POWER switch.
2 Set the pen lever to the CHART SET (top)
position and lock the lever in place by moving
it to the left.
The platen will be raised, and the pens will automat-
ically move to the far right.
3 Hold and shake the recording paper by the
edge to separate the sheets.
4 Load the recording paper into the chart holder
with the round holes on the left and the oval
holes on the right.
(Load so that the side of the paper with the red
marks along the edge is on the bottom.)
5 Open the chart cover, pass the top of the
recording paper through the opening, and pull
the top edge through.
6 Align the paper so that the sprockets engage
the round holes on its left edge.
7 In the same way, align the paper so that the
sprockets engage the oval holes on its right edge.
8 Close the chart cover.
9 Set the pen lever to the UP (middle) position.
The platen will be lowered.
