Why are PM700s pulse weights different on different PM700s?

Issue
Some PM700 have the possibility for adjusting pulse weight to 0.01 kWh/pulse even though the documentation says the minimum value that can be set is 0.1 kWh/pulse.

Product Line
PM700

Environment
Firmware

Cause
OS 2.020 added a higher amount of accuracy for the pulse weight option.

Resolution
With firmware OS 2.020, the lowest pulse weight value that can be set on the meter was reduced from 0.1 to 0.01kWh/pulse. That is to say, starting from firmware version OS 2.020, lowest pulse weight option is now 0.01 kWh/pulse instead of .1 kWh/pulse.
