Instruction manual

ST : In case of the ST series, do not change the settings. If changed, weighing will not be performed properly.
Function #
Function name Range
Default
CALF-19 ST Zero Input Voltage 0.000000 - 2.200000 (mV/V) 0.000000
Input Voltage (mV/V) from the Load Cell at "Zero", which is determined in "Zero Calibration" with
weights.—Actual load calibration
CALF-20 ST
Span Input Voltage
(Capacity to zero)
0.000000 - 3.2000000 (mV/V) 3.200000
Input Voltage (mV/V) from the Load Cell at "Span", which means the difference between Capacity and
Zero. The voltage is determined in "Span Calibration" with weights—Actual load calibration.
CALF21 ST
Weight against Span
Input Voltage
0 – 800000
(Decimal point ignored)
16000
When "Digital-Calibration", calibration not using weights, is performed, CALF-19 and CALF-20 as well
as CALF-21 also have to be done. Refer to the following.
* This setting will be changed to capacity (CAL-04) if actual load calibration is
done.
* For future load cell replacement, keep a record of the CALF-19, CALF-20, an
d CALF-21 settings.
(Use {APPENDIX F: User’s setting record}.)
* Accuracy at replacement: 1/500 approximately
* Revising CALF-19, CALF-20, and CALF-21 settings can perform “Zero calibration” and “
Span
calibration”.
* Accuracy of digital span calibration: 1/1000approximately
* Accuracy of the output from the load cell depends
on the calibration conditions.
* Actual load calibration is highly recommended for a better accuracy. Perform digital span
calibration only whe
n calibration with weights can not be done.
