Level One Hidden Diagnostics Values – continued
•
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.
•
4-20(3) Zero
= Analog counts to calibrate zero on analog output 3.
•
4-20(3) FScale
= Analog counts to cal. full scale on analog output 3.
•
Ext. 4 mA Cal.
= Enter 0 for auto calibration or enter factory supplied A/D counts. Note: You must connect a known
4.00 mA input if you are going to calibrate the unit.
•
Ext. 20 mA Cal.
= Enter 0 for auto calibration or enter factory supplied A/D counts. Note: You must connect a
known 20.00 mA input if you are going to calibrate the unit.
