Have MTL32 opened with the calibration menu displayed at the bottom.  You may need to log in as administrator in MTL32 to show this screen.  Click 'user' and then 'administrator' in MTL32.  Some may have a password prompt which will be testresources.

1.) Verify loads along the range of the load cell to see if its within tolerance.  Within +/- 1% of reading is typical industry standard, consult quality standard/procedure if different.  If all readings are with in that tolerance then no adjustment is needed and you don't need to proceed.

2.) If some or all readings are outside of the tolerance then you'll need to adjust the calibration and then verify.  Look at the points where the calibration is out of tolerance 1-3. points and recalculate a new shunt value using the formula below.

(Applied load from traceable device or weight / Reading from MTL32) x Current shunt value.

If you are calculating using 2 or 3 points add up those new shunt values and divide by the number calculations you did to get an average shunt.  Note: this might be useful where you are within tolerance in portion of the range and but out at others.  Sometimes 1 point adjustment is all that is needed but and average may be needed.

4.) Remove any load from the load cell.  Input the new shunt value in the shunt setting below.

Note: screen shot is for reference purposes only.  Do not change settings to match picture

5.) Press the yellow 'C' button to apply the new shunt value.  You may see the ''Range' setting shift.  You can use the Gain 1 and 2 settings to bring the 'Range' back towards the range setting that was previous in there.  If you see the Yellow live readout shift you can use the 'h/w offs' to adjust so it is as close to zero as possible.  Once those changes have been made click the 'C' button again.  There will be more of a slight shift in numbers but small compared to previous.

6.) Apply load again and verify the measurements are within tolerance.  If they are still out of tolerance.  Repeat the above process, this time using the new shunt value in the equation.
