7) Automatic sensitivity calibration step 4
Stop the weight loader system, and when stable, measure the zero point mass value.
Calculate the sensitivity correction coefficient, and store in NVRAM again.
8) Automatic sensitivity calibration step 6
After several seconds display, it returns to the mass display (state before execution of automatic
sensitivity calibration).
While detailed error codes are not displayed in user mode, they are displayed in service mode, as shown in
the table below. To return from the error display, press the [Break] key.

Description
Unstable Error (CAL E1)
Measurement value during zero
point
and
weight
mass
measurement is unstable.
Zero Change Error (CAL E2)
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.
Weight Error (CAL E3)
Difference
between
reference
weight value and measured weight
span value during PCAL exceeds
2 % of the reference weight value.
Span Change Error (CAL E4)
Difference
between
the
set
reference weight value and the
measured weight span value
exceeds 2 % of the weight mass.
i. Operation and execution of sensitivity calibration, and the operating procedure for the sensitivity
calibration menu is the same as in the user mode, and does not appear as a service mode menu item.
ii. Prepare the reference weights listed in the table below for CAL values.
