17.1.4
Calibration of Zero point only
Each item of the low chart corresponds to each procedure described in Chapter
①
Changing to Zero point only calibration mode
②
Zero stability check
③
Zero calibration using weight
④
Finish Zero point only calibration mode
Note:
-
Calibrating by transmission
(-RS-) is displayed.
-
When the calibration is force inished, all data returns to its condition prior to
calibration without registration.
-
Be sure to register the data for calibration with a weight after conirming the
condition is stable.
17.1.4.1
Changing to Zero point only calibration mode
Write 12 in maintenance address 56853 and proceed to Zero point only calibration mode
17.1.4.2
Zero stability check
Stable/Unstable is read from holding register address 56845 with no load on the load
cell.
0: Unstable
1: Stable
17.1.4.3
Zero calibration by weighing value
The load cell output value is registered in holding register address 72 as the Zero point.
[1] is written in holding register address 72.
[1] is automatically rewritten as [0] after writing is complete.
Setting range: 1
TE-L error
[20] (TE-L) is written in input register address 52 when the read load cell output value is
less than –2.5 mV/V, which is outside the range of zero calibration on the negative side.

Zero point < –2.5 mV/V
TE-H error
[21] (TE-H) is written in input register address 52 when the read load cell output value is
more than 2.5 mV/V, which exceeds the range of zero calibration on the positive side.
