- Sensitivity cell 1 [mV/V]
- Sensitivity C of the first load cell: output in millivolts per volt of excitation (mV/V) when exactly its rated load acts. Small cell-to-cell differences cause corner errors and are trimmed here. Source: the cell's individual test or calibration certificate, not merely the general datasheet; usually stated to four decimals.
- Output resistance cell 1 [Ω]
- Output resistance of the first cell, measured between its two signal leads. It determines how strongly the cells load one another in the parallel connection. Source: the datasheet gives only a nominal value (e.g. 350 Ω ± 3 Ω); for trimming measure with a precision ohmmeter to 0.01 Ω.
- Sensitivity cell 2 [mV/V]
- Sensitivity of the second load cell: output in mV/V at rated load per its test certificate. All cells of one scale should share the same nominal sensitivity; the small differences in the decimals are what is equalised here.
- Output resistance cell 2 [Ω]
- Output resistance of the second cell between its signal leads, measured with a precision ohmmeter to 0.01 Ω (not the datasheet nominal – its tolerance exceeds the trimming effect).
- Sensitivity cell 3 [mV/V]
- Sensitivity of the third load cell in mV/V at rated load from its test certificate; enter to four decimals so the trimming can capture the production scatter at all.
- Output resistance cell 3 [Ω]
- Output resistance of the third cell between its signal leads, measured with a precision ohmmeter to 0.01 Ω; the cell must be unloaded and disconnected from the amplifier.
- Sensitivity cell 4 (0 = not used) [mV/V]
- Sensitivity of the fourth load cell in mV/V at rated load from its test certificate. If the scale has only three cells (e.g. a vessel on three supports), enter 0 – the cell is then ignored.
- Output resistance cell 4 [Ω]
- Output resistance of the fourth cell between its signal leads, measured with a precision ohmmeter to 0.01 Ω. Irrelevant if C₄ = 0 is entered.
