Gas Inlet and Outlet
Gas to be measured is connected to the ¼ inch push-connect
IN
port.
The acceptable inlet gas-pressure range is 0 to 15 psig.
The ¼ inch push-connect OUT port may:
Remain open, expelling non-hazardous gas into the air,
Be routed to a different location or system, or
Be recirculated through an enclosed gas-flux chamber.
Power
The analyzer is operational for up to 3 hours when using the internal battery only.
The battery may be recharged using the AC/DC power supply to the DC power
inlet. This power supply contains a 10 A 32 V DC automotive fuse inside the external
power-input harness.
There is also an optional battery charger (ACC-MICRO-BC) when extra batteries
need to be charged outside the analyzer.
WARNING!
Do not use a battery other than the battery provided by ABB.
