Pressing the Return button at the bottom right of the operator interface on any screen will take the
display to the default. It may be necessary to press the Return button multiple times.
Pump Operation
Initially, the pump will be off. The pump should remain off while sampling an endothermic generator or
any other atmosphere under positive pressure. The pump should also remain off during calibration. For
proper operation, the flow of gas through the sensors should be between 1.0 and 2.0 SCFH. If the flow
meter on the right of the screen or on the inside of the lid does not indicate sufficient flow, turn the pump
on. When accessed from the main screen, the pump has two possible modes: Automatic and Off.
Carbon Calculation
The MGA 6010 determines the percent carbon in the sample gas using measured amounts of CO, CO
2
, and
CH
4
along with the Furnace Temperature. The Furnace Temperature is either entered by the user or
obtained automatically from the Furnace Temperature Controller via RS-485 communications.
Additionally, the carbon percentage measured by the MGA 6010 can be used as a comparison to the
carbon percentage measured by a furnace’s oxygen probe. This is accomplished either by manually
entering the Probe Temperature, Probe Millivolts, and the Probe CO Factor into the MGA 6010 or by
obtaining the information automatically via RS-485 communications to the Furnace Carbon Controller.
Providing the probe information allows the MGA 6010 to suggest an adjustment for the probe CO Factor
(or Process Factor) in order to keep the oxygen probe measuring properly.
