 ## R6581T Adjustment Toolkit
 A toolkit to dump INL calibration constants of the R6581 DMM and update them to fit a reference DMM's.
- - Run toolkit with two meters
- - Compensate INL
- - Look at data

+
+# 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 to 92 for your DMM and source.
+3. You can opt to comment out line #63 to 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.
