The Operational Status and Condition Registers
The operation status register provides information about the operation of the
meter. Bits in the operational status event register are latched from changes in the
bits in the operational status condition register.
The meter only uses a single bit (bit 8) in these registers. This bit indicates the
settling state of the digital filter. If the digital filter is enabled, bit 8 is set to 1 to

operation of the digital filter.
