6.20 Over-range
Numerical over-range of the rate or total displays is
indicated by all the digits displaying ‘9’ and all the
decimal points flashing.
When the total display exceeds 99999999 or -
9999999 it will not automatically roll-over to zero and
continue counting, but the grand total will continue to
count. If it is likely that the total will exceeds
99999999 or -9999999 the grand total, which has a
capacity of 10
16
and –10
15
counts, should be reset to
zero at the start of the operation.
If the total display exceeds 99999999 or -9999999
when the BA354NE has been configured for
bi-directional flow, the total display will be locked
and will not record flow in the opposite direction to
the over-range, although the grand total will continue
to function.
