## Technical definitions of terminology

1. RATED CAPACITY(R.C)
The maximum axial load that a load cell is designed to measure within its specification.
2. RATED OUTPUT(R.O)
The algebraic difference between the outputs at no-load and at rated load.
3. NON-LINEARITY The maximum deviation of the cali-bration curve from a straight line between zepo and rated load outputs, expressed as a percent of the rated output and measured on increasing load only.

4. HYSTERESIS The maximum difference between output readings for the same applied load one point obtained while increasing from zero and the othr while decreasing from rated output. The points are taken on the same continyuous cycle. The deviation is expressed as a percent of rated output.

5. REPEATABILITY The ability of a load cell to reproduce output readings when the same load is applied to it consecutively, under the same conditions, and in the same direc-tion. Repeatability is expressed as the maximum difference between output readings as a percent of rated output.

6. ZERO BALANCE
The output signal of the load cell with rated exitation and with on load applied, usually expresed in percent of rated output.
7. TEMPERATURE RANGE, COMPENSATED
The range of temperature over which the load cell is compensated to maintain rated output and zero balance withn specific limits.
8. TEMPERATURE RANGE, SAFE
The range of temperature over which the load cell may be safely operated up to full scale without causing failure but specifications may not be met.
9. TEMPERATURE EFFECT ON RATED OUTPUT
The change in rated output due to a change in ambient temperature. Usually expressed as +/- a percentage change in rated output per degree C change in ambient temparature, over the compensated temperature range.
10. TEMPERATURE EFFECT ON ZERO BALANCE
The change in zero balance due to a change in ambient temperature. Usually expressed as +/- a percentage change in rated output per degree C change in ambient temperature, over the compensated temperature range.
11. TERMINAL RESISTANCE, INPUT;
The resistance of the load cell circuit measured at the excitation terminal, at standard temperture, with no-load applied, and with the output terminals open-circuited.
12. TERMINAL RESISTANCE, OUTPUT
The resistance of the load cell circuit measured at the output signal terminals, at standard temperature, with no-load applied, and with the excitation terminals open-circuited.
13. INSULATION RESISTANCE
The DC resistance expressed in ohms measured between any electrical connector pin or lead wire and the load cell body or case. Normally measured at 50 V DC.
14. EXCITATION
The voltage or current applied to the input terminals of the load cell.
