Starting on screen
(1) Tap on the Home/Main screen > Calibration
(2) Tap to select Automatic zero calibration.
(3) Confirm the calibration contents (target channel for automatic zero
calibration and calibration range) on the screen that appears. If there are
no problems, tap [Start calibration]. Automatic zero calibration starts and
the measurement screen appears.
• On the measurement screen, the indicating that calibration is in
progress is displayed at the top of the screen. Ch (component) subject
to simple zero calibration switches to the calibration range. During zero
calibration, appears on the Ch (component) subject to simple zero
calibration, and zero calibration is performed at the same time.
• When the zero calibration is completed, replacement time starts and
the blinks.The range returns to the pre-calibration range. After the
replacement time has elapsed, the goes off and the system returns
to the measurement state.
l
Remote start
To perform an automatic zero calibration, close (short-circuit) the input terminal to which
"Automatic zero calibration start" is assigned in the contact input setting and open (release) it
after at least 1.5 seconds. (For contact input settings, see 5.2.4 Contact input setting)

CAUTION
• If a setting confirmation dialog box appears when starting simple zero calibration and simple
zero calibration cannot be started, the contact output setting is insufficient. See 5.2.3
Contact output setting to assign the necessary functions.
• If a zero calibration error occurs during the execution of automatic zero calibration, an auto-
calibration error occurs. This auto-calibration error will be resolved when the next automatic
zero calibration is successfully performed or manual calibration is performed, regardless of
success or failure.
• A calibration stability error may occur due to insufficient flow time when performing an
automatic zero calibration. To cancel the error, perform manual calibration or adjust
the flow time and perform the automatic zero calibration again. See 5.1.3 Auto zero
calibration setting for more information on flow time settings.
