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 deci-
bels. Normally reads zero. If this value is consistently -5 or
-10, for example, the Ck or density setting may be wrong.
•
O,I = factory use only.
•
Pulse Out Queue = Pulse output queue. This value will ac-
cumulate 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 flow rate decreases. A better practice
is to slow down the totalizer pulse by increasing the value in
the (unit)/pulse setting in the totalizer menu.
•
TOF, G, f = factory use only.
•
Sig. Rev = Signal board hardware and firmware revision.
•
Miro Rev = Microprocessor board hardware and firmware re-
vision.
•
AD, R, T, F, PT, V = factory use only.
•
SPR Err, Rcv, Sent = factory use only.
Column Two Hidden Diagnostics Values
• 4-20(1) Zero = Analog counts to calibrate zero on analog out-
put 1.
• 4-20(1) FScale = Analog counts to cal. full scale on analog
output 1.
• 4-20(2) Zero = Analog counts to calibrate zero on analog out-
put 2.
• 4-20(2) FScale = Analog counts to cal. full scale on analog
output 2.
• 4-20(3) Zero = Analog counts to calibrate zero on analog out-
put 3.
• 4-20(3) FScale = Analog counts to cal. full scale on analog
output 3.
• Alarm (1) Test = Used as a test to verify that the alarm circuit
is functioning. When low is selected the alarm will initiate a
low alarm on the output. When High is selected it will give a
high alarm on the output.
• Alarm (2) Test = Used as a test to verify that the alarm circuit
is functioning. When low is selected the alarm will initiate a
low alarm on the output. When High is selected it will give a
high alarm on the output.
