7 Troubleshooting
7.1 General guidelines
Troubleshooting a Micro Motion flowmeter is performed in two parts:
1. Tests of wiring integrity
2. Observation of the transmitter's diagnostic tools, which include the
diagnostic LED, diagnostic messages, and fault output levels
CAUTION
During troubleshooting, the transmitter could produce
inaccurate flow signals.
Set control devices for manual operation while
troubleshooting the flowmeter.
CAUTION
Rotating the transmitter housing cover or adjustable
faceplate could cause the display to change, the
flowmeter to be zeroed, or totalizers to be reset.
Rotating the transmitter cover actuates the Scroll and
Reset knobs, which will affect the screen that is displayed,
and could zero the flowmeter or reset the transmitter flow
totalizers.
Do not rotate the transmitter housing cover or adjust the
faceplate while RATE, TOT, or INV screens are
displayed.
Security settings that prevent the use of scroll and reset
knobs also prevent this situation from occurring. For
information about security modes, see
Section 2.3
