Lvl
Threshold level. If the Low Flow Cutoff in the calibration menu is
set above this value, the meter will read zero flow. The Lvl level
can be checked at no flow. At no flow, the Lvl must be below the
Low Flow Cutoff setting or the meter will have an output at no flow.
Adj. Flilter
Adjustable filter. Displays the filtering in decibels. Normally reads
zero. If this value is consistently -5 or -10, for example, the Ck or
density setting may be wrong.
Iso. Power Volts Nominally 2.7 Vdc, if less than this check the flowmeter input power.
O,I Factory use only.
Pulse Out Queue
Pulse output queue. This value will accumulate if the totalizer is
accumulating faster than the pulse output hardware can function.
The queue will allow the pulses to"catch up" later if the flowrate
decreases. A better practice is to slow down the totalizer pulse by
increasing the value in the (unit)/pulse setting in the totalizer menu.
