● The load value display is not stabilized.

　▶ An indicated value may not be stabilized because of the influence of vibration.　 You can stabilize an indicated value by three kinds of filter facilities of analog filter, digital filter, and stabilized filter.　　 Refer to the operation manual for details, such as the setting method of these functions.

The calibration is an operation that matches the load of the sensor to the display of this instrument to display the electrical signal from the sensor (load cell) as an accurate load.

Here, we explain the calibration procedure from a factory-shipments state based on the condition at the factory-shipment. As an example, we explains by the case that the weight of 4 ton can be prepared, the weighing value is 6.000 ton and a scale interval is 0.002 ton.We describe the example that zero is registered by [Calibration at zero by the weight], span is registered by [Calibration at span by the weight] or [Calibration at span with inputting the numeric value].

（SPAN）（S MV）

ZERO is registered by reading the load cell output value in the condition that nothing is put on the weighing section. (Initial condition including tare.)

When CSD-892-76 used is replaced with another unit and only when all the below requirements are accepted, ZERO calibration by the value input can be applied.　・When ZERO calibration data before the replacement remains. 　・When the condition that nothing is put on the measuring section (such as an initial load) is impossible.

SPAN is registered by inputting the value in which the load cell output value at zero is subtracted from the load cell output value assumed when loaded for rating weight.

SPAN is registered by reading the load cell output value in the condition to put the weight set in step 6 on measuring part.
