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.
