Chapter 3. Operating Instructions
3.3.12 The Diagnostics Menu
Use the Diagnostics Menu (see Figure 64 on page 70 ) to simulate operation and review the system files. The system
log files contain time/date stamped messages including: power on, power off, programming time outs, parameter faults,
incorrect password entry and other various information relative to system operation and programming.
The simulated inputs are for testing the meter to verify that the programming is correct. They are also used to enter
nominal operating temperature and pressure for the V only model. Simulated vortex frequency allows you to enter any
value for the sensor input in Hz. The meter will calculate a flow rate based on the corresponding value and update all
analog outputs
(
the totalizer display and output is not affected by a simulated frequency
) . The simulated pressure and
temperature settings work the same way. The meter will output these new values and will use them to calculate a new
density for mass flow measurement.
Note:
When your diagnostic work is complete, make sure to return the values to zero to allow the electronics to use
the actual transducer values. For the
V only model, keep the temperature and pressure at nominal operating
conditions.
If the meter display indicates a temperature or pressure fault, a substitute value can be entered to allow flow
calculations to continue at a fixed value until the source of the fault is identified and corrected.
The units of measure of
the displayed values are the same as the units configured for the flowmeter
.
