• Acquisition Module (P/N 1-360-03-008) (T-21, T-22, T-41, T-200)

Should the Daniel 3410 Series Ultrasonic Gas Flow Meter require disassembly in the field
(i.e., check boards, change switch settings, or replace boards), to prevent electrostatic
damage to the electronic boards, always use a ground strap while handling the circuit
boards. If one is not available, ensure you are electrically discharged before touching the
boards by first touching a metal surface such as a ground lug on the meter or a table.
