Before complete failure, pressure switches are often out of calibration for a wide variety of reasons, which can cause the furnace to operate in an unsafe manner.
The DDSM1 Draft Simulator creates a controlled vacuum to test pressure switches, so technicians can tell exactly when a pressure switch closes and opens. This either proves that the switch is within spec, or identifies if the switch is starting to fail.
Plus, the DDSM1 is the only tool available to calibrate adjustable pressure switches to manufacturers specifications. This saves contractors from carrying a large inventory of pressure switches on their trucks, and from leaving the job site to buy pre-calibrated switches
