3.5.13 The Diagnostics Menu
Use the Diagnostics Menu (see Figure 107 on page 93 ) to simulate operation and review the system files. The system
log files contain time/date stamped messages including: power on, power off, programmed 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 flow meter .
