## R6581T Adjustment Toolkit
|
|
A toolkit to dump INL calibration constants of the R6581 DMM and update them to fit a reference DMM's.
|
|
|
|
|
|
# How to set up
|
|
1. Download repository
|
|
2. Open Hosei.py and adjust the following for your setup:
|
|
- libraries (uses a pyvisa compliant alternative for USB-CDC GPIB adapter)
|
|
- lines #19-21 for the GPIB adresses
|
|
- lines #36-42 for your voltage source configuration
|
|
- lines #43-54 for your reference dmm configurations
|
|
- the measurement functions from lines #74-92 for your DMM and source.
|
|
3. You can opt to comment out line #63-72 if you do not wish to clear your initial coefficients for the first sweep.
|
|
4. Run and wait
|
|
|
|
There are some basic pareametersd also like nrepeats, which defines the amount of INL sweeps to be averaged.
|
|
Note that this is a tradeoff of thermal effects against DMM noise
|
|
|
|
Typically with Datron 4805 and 3458A I get within +-0.1 uV/V of the reference DMM (3458A) on an average correction fit. |
