Procedure

1. Read & follow the manufacturer’s manuals, to decide the correct procedure for initial startup of the meters.
2. Test the condition of the batteries before each use. lf low (below 500 for the 320P/D or out of test limits for the 320P) then the unit must be recharged before use. It is recommended that the charge should be overnight for 14 hours.
3. Check the condition of the filter material on the back of the unit. Change it if it is wet or dirty. 4, Remove the cell saver cap, check the oxygen calli- bration with non-tainted or polluted ambient air (20.9%) with the 320P on the high range scale. The 320P/D will auto-range. Adjust with the span dial as necessary. Then install the flow through adapter cap on the O2 fuel cell holder.
5.Connect the temperature reducing tubing to the engine exhaust system. A. Turbocharged engines have a 1/4” npt fitting in the exhaust elbow after the turbocharger and naturally aspirated engines have a 1/4” fitting in the exhaust manifold. Use 10 to 15 feet of 3/8” tubing (Copper or Stainless Steel) and connect to the 1/4” fitting.
