9) Stop the weight loader system, and when the mass value is stable, automatically measure the mass.
10) Drive the weight loader system, and unload the internal weight from UniBloc.
11) Stop the weight loader system, and when the zero point mass is stable, measure the mass (Z int).
12) Attach an instrumental error to the internal weight, and re-store in NVRAM.
13) Automatic sensitivity calibration (ICAL) starts up next.

Sensitivity Calibration
5.7.1.
External Weight Calibration ECAL
5.7.1.1. Operation Procedure and Process
(1) Press and hold down the [CAL] key for at least 3 seconds.
(2) "E.CAL" is displayed. Press the [O/T] key.
(3) The calibration weight value starts flashing. Place the weight.
If the weight value changes, press the [MENU] key during weight value flashing.
The weight value input display appears. See "5. Numerical Input Operation" and input the weight value.
(4) If an error occurs, the displays in the following table appear.
Display
Error Name
Description
CAL E1
Instability error
Measurement value during zero point or weight mass measurement is
unstable.
Stabilization mark failed to light up even after 15 seconds had elapsed since
weight was placed or removed.
CAL E2
Zero point error
Drift in zero point from last sensitivity calibration is large. Object exceeding
20 % of weight capacity is placed on the pan, or a change in the zero point
equivalent to excess of 20 % of weight capacity occurred.
CAL E4
Span error
Difference between the set reference weight value and measured weight
span value exceeds 2 % of the weight mass.
Pressing the [BREAK] key returns to the AD value display.
(5) If the "END" display appears without an error occurring, return to the AD value display.
