3. Apply the gas listed on the Data Label to the inlet at the recommended pressure (listed on the Data
Label/Calibration Certificate). Your 50 Series will begin to measure mass flow. This will be
displayed on the user software or local display.
4. You will need a setpoint input in order to control flow. Do so carefully! You can digitally input a
setpoint using the user software or control directly with your analog setpoint source if you ordered
the analog option. NOTE: The unit ships in the configuration ordered. This information is also listed
on the Data Label and on the Calibration Certificate. This information is also inherent in the model
code. See the Instruction Manual for more details.
5. DO NOT leave a setpoint applied for an extended period of time to a controller when the gas supply
is off or blocked. Damage may result from excessive heating, and the unit will become hot
enough to burn you. In this case you should adjust your setpoint to 0.000 or power down the unit.
