Use the Diagnostics Menu 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 turbine frequency allows you to enter any value for the sensor input in Hz. The meter
will calculate a flowrate based on the corresponding value and update all Analogue 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.
