TERMS

DEFINITIONS

Rated CapaCity (R. C.)

The maximum force measured by continuous test of load cell according to its specifications.

Rated Output

The value subtracted output value of no load from output value of rated capacity. Generally, it is expressed as mV/V or relative strain.

Non-Linearity

The maximum deviation of calibration curve against the straight line between no load output and rated output, and expressed by percentage of rated output. It is measured while being loaded.

Hysteresis

The maximum difference of output value of load cell between load is increased and load is decreased, and is expressed by percentage of rated output.

Repeatability

The maximum difference of output value among results of repeated tests under the same loading conditions and environment. It is generally measured at the rated capacity and expressed by percentage of rated output.

Recommended Input Voltage

The voltage with that the load cell can perform its optimum function.

Maximum Input Voltage

The maximum voltage at which the load cell is not damaged.

In this case, the load cell can perform its function, but the result is not guaranteed.

Input/Output Resistance

Resistance value at input or output terminal when no load is The direct current resistance between the load cell circuit and the load cell itself. Normally, it is measured at DC50V.

Compensated Temperature

The temperature range being compensated to keep the rated output and zero point within the setting range.

Operating Temperature Range

The temperature range that can be used without deforming the characteristics of load cell.

Temperature Effect on Zero Balance

The variation of zero balance when the environment temperature is varied. It is generally expressed by percentage of variation per 1°C to rated output.

Temperature Effect on Rated Output

The variation of rated output when the environment temperature is varied. It is generally expressed by percentage of output variation per 1°C to rated output.

Safe Overload Ratmg

Limit of load that will not cause permanent deformation of load cell. It is expressed by percentage of rated capacity.

Initial Bridge Balance

Percentage of output at no load to output at rated capacity when the load cell is normally installed.
