QUICK START GUIDE

README FIRST!

To zero the instrument, allow 30 minutes to one hour for warm-up time Pass 20% flow (~1VDC output) through the instrument for 5 minutes. Stop flow and insure that there is no leakage. Wait 2 minutes, then adjust the zero potentiometric. Unpack and Inspect all items for any obvious signs of damage due to shipment. Immediately advise the carrier who delivered the shipment if any damage is suspected. Insure that all parts are present (e.g. flow meter, switched mode powersupply, cable, etc.) Insure that instrument options are correct (e.g. output, range, gas, pin out, etc.)
