#104329 - How many??
Responding to: ???'s previous message
Ravi P said:
1,00,000

Do you mean 100,000 (one hundred thousand), or 1,000,000 (one million)?
(or 100.000 or 1.000.000, if you prefer)

Even with the lower option, you're still trying to accomodate a range of 1g to 100kg (or whatever).

To put it another way, you're trying to resolve tens of parts per million - do you really need this precision?
