Can I calculate the expected millivolt reading of my scale?

Can I calculate the expected Millivolt reading of my scale?  I want to place a test weight on the scale and know what the expected signal Mv load cell output increase will be.

To calculate what the expected millivolt reading should be, use the following formula:

(Applied load/Scale capacity) * Sensitivity * Sense voltage = the Expected Millivolt increase

Dividing the number of lb or kg placed on the scale by the load point capacity will give you a percentage. Multiply that percentage times the load cell sensitivity found on the load cell certificate. To find the total change, multiple the sensitivity times the sense voltage.

Example:

Applied load = 100 kg

Scale capacity = 500 kg (This is the total capacity of all the load cells, not the rated capacity or max load capacity.)

Sensitivity = 2.0005 mV/V

Sense Voltage is 4.93 VDC

Starting mV reading

Expected mV increase is 1.97 mV
Use the sense lines as reference. The voltage drop over the Excitation lines are monitored by the sense lines and set the internal reference point for full scale.

If the sense lines are not used to measure the actual excitation voltage at the junction box an error may be introduced. The error will be equal to the percentage of excitation voltage lost due to cable resistance between the instrument and the junction box. If the excitation voltage at the back of the instrument was 5 volts and the excitation voltage at the junction box was 4.95 volts, 0.05 volts was lost due to cable resistance. This loss will cause a linear error of 1% of applied load in all weight readings. This error is introduced because the programmed millivolt per volt data of the load point is multiplied by the voltage between the sense lines to compute the calibration curve of the load point.
