Note 1 – To Calculate Drift Specifications (into ppm) use the following formulas:
For Drift @ Point 1 (
µΩ/Ω
) Calculate Using formula:
((Current Cal
Value Point 1
– Last Cal
Value Point 1
)/Last Cal
Value Point 1
)*1E

For Drift @ Point 2 (
µΩ/Ω
) Calculate Using formula:
((Current Cal
Value Point 1
– Last Cal
Value Point 1
)/Last Cal
Value Point 1
)*1E

For Drift @ Point 3 (
µΩ/Ω
) Calculate Using formula:
((Current Cal
