<Calibration Procedure>
Starting Semi-Auto Calibration from the Display
1) From the basic display display if you touch the Setup key, the [Execution/Setup]
display appears. Select [Calibration].
2) Next select [Semi-auto calibration]. The [Semi-autocal] channel select display,
Fig 9.8, is displayed.
3) Select the channel to be calibrated. The [Semi-auto cal.] display, Fig. 9.9, is dis-
played.
4) When you select [Start calibration] the [Semi-autocal] trend graph of Fig 9.10 is
displayed, and Span calibration begins.
5) When the preset calibration time has elapsed, Span calibration ends and Zero calibra-
tion begins. Likewise, when the preset calibration time has elapsed, Zero calibration
ends. After a preset stabilization (settling) time, the instrument reverts to measure-
ment mode.
6) Touch the Escape key (icon of door with arrow) to abort calibration. If you abort
Span or Zero calibration then calibration time is skipped and stabilization (settling)
time starts. If you touch the Escape key again then stabilization (settling) time is also
skipped, and you revert to the Basic display.
