Decade Box Verification (example)
The averaging system can be verified using the Delta R calibration sheets and decade boxes to simulate the
delta R signal from the flow elements. The following example begins with the instrument wired for input
power, the Slave flow output is connected the Master Aux 1 input and both instruments are set up using
the same flow units.
The master unit can be switched between the Average Flow on and normal Flow modes to view the results
of the averaging function. This switching is done in the 2.4.2. Menu under the Mode selection.

Mode = Average Flow
Values for Aux1, Aux2, Enabled and Mode = Average Flow, indicates that the instrument is correctly set up
for averaging flow. Each instrument will have different values for Aux1 and Aux2 depending on the specific
instrument set up.
