LA-55:
|
|
DAC full range is 40A
|
|
Actual bits is 16
|
|
Stable bits is ~21
|
|
|
|
CT full range is 55 A (FR + 0.5 bits)
|
|
CT used range is 100 mA (FR - 8.5 bits)
|
|
ADC resolution over used range is about 8.5 bits
|
|
Which would give us (FR - 17 bits)
|
|
-- IF the LA-55 can measure 300uA.
|
|
This would be 17.5 bits at its full range.
|
|
Spec is around 1% = 7 bits.

|
CT-0.1:
|
|
DAC full range is 60A
|
|
Actual bits is 16
|
|
Stable bits is ~21
|
|
|
|
CT range is 5 mA (FR - 13 bits)
|
|
ADC resolution over this range is about 8.5 bits
|
|
Which would give us (FR - 21.5 bits)
|
|
-- IF the CT-0.1 worked at all.. it's broken.
|
|
It would be measuring 20uA.
|
|
This would be 12.2 bits at its full range.
|
|
Spec is around 1% = 7 bits.

A6302:
|
|
DAC full range is 20A
|
|
Actual bits is 16
|
|
Stable bits is ~21
|
|
|
|
CT range is 180mA (FR - 6.8 bits)
|
|
ADC resolution over this range is about 11 bits
|
|
Which would give us (FR - 17.8 bits)
|
|
-- Except CT resolution is only about 4 bits at this range.
|
|
Which gives us 10.8 total, at best.
