Technicians calibrate the unit by backing off the adjusting screw to find the "zero vibration point" while the machine is idle

Common signs include the burner failing to light despite a call for heat

It operates via a standard 4-20mA current loop and is fully compatible with RS-485 network protocols

while the integrated 1/8" NPT upstream and downstream pipe taps simplify routine leakage testing

The encapsulated design protects internal windings against moisture and vibration
