6.4 Analogue output calibration
To check the 4-20 mA circuit, connect a DVM in series with the output loop. Select zero or
full scale (from the second column of the hidden diagnostics) and then actuate the enter key
twice. This action will cause the meter to output its 4 mA or 20 mA conditions.
If the DVM indicates a current greater than ±0.006 mA from 4 or 20, adjust the setting up or
down until the output is calibrated.
Note: these settings are not for adjusting the output zero and span to match a flow range,
that function is located in the Output Menu.
6.5 Troubleshooting the flowmeter
Warning!
Before attempting any flowmeter repair, verify that the line is not pressurized.
Always remove main power before disassembling any part of the mass
flowmeter. Use hazardous area precautions if applicable. Static sensitive
electronics - use electro-static discharge precautions.
6.6 First check items:
-
Installation direction correct
-
Installation depth correct (insertion style meter)
-
Power and wiring correct
-
Application fluid correct
-
Meter range correct for the application
-
Meter configuration correct
-
Describe Installation Geometry i.e. upstream diameters, valve position, downstream
diameters, etc.
6.7 Record values:
Record the following values from the Run menu with the meter installed in order to
determine the operating state of the flowmeter:
With Flow
With No Flow (if possible)
