	<...calibration range...> -400mm to +2000mm H₂O should cover it. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	Assuming that you have PADS ( Remote Diaphragm with Capillary) on both HP & LP side of Transmitter, after installation with empty tank Calibrate the Transmitter for ZERO, then your range should be 1500 x 1.25 = 1875 mm H2O LRV = 0 mmH2O & URV = 1875 mmH2O 250 mmHG Vacuum will be cancelled automatically as it is acting on both HP & LP sides of Transmitter.
