How is the equalizer used during transmitter calibration?<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To zero the transmitter, first close both isolation valves, then open the equalising valve to equalise high\u2011 and low\u2011side pressures. The transmitter should output 4 mA (or 0%); if not, adjust the zero.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Q2. Can a direct\u2011mount manifold fit transmitters from different brands?<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As long as the flange center\u2011to\u2011center distance and bolt pattern match, most will physically fit. However, sealing face roughness and gasket material requirements may vary between brands\u2014using the same brand or obtaining written compatibility approval is advisable.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Q3. When should I choose a 5\u2011valve over a 3\u2011valve?<\/span><\/p>\n<p><span style=\"font-weight: 400;\">When the process fluid is dirty, prone to condensation, or requires frequent venting. The two extra vent ports on a 5\u2011valve allow independent purging of the high and low sides without interfering with the equalising valve operation.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Q4. What do the handle colors mean on a manifold valve?<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Industry\u2011standard color coding (used by NPT\u2011LOK and others): Black = isolate\/block, Red = test\/vent, Green = equalize.
