this menu can be compared to the actual Ck setting in the
calibration menu to help determine if the Ck setting is correct.
•
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 flow meter 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 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
revision.
•
AD, R, T, F, PT, V
= Factory use only.
•
SPI Err, Rcv, Sent
= Factory use only.
•
Version Retries =
Factory use only.
•
Internal Temperature =
Electronics temperature.
•
Dens. Calc Time =
Factory use only.
•
Rel. Roughness =
Factory use only.
Level Two Hidden Diagnostics Values
•
4-20(1) Zero
= Analog counts to calibrate zero on analog
output 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
output 2.
•
4-20(2) FScale
= Analog counts to cal. full scale on analog
output 2.
