5.1.2. ZERO SPAN VALVES WITH IZS (OPT 51B)

Because of the addition of the auto-reference gas path and the multi-tube Nafiondryer, the internal pneumatics gas flow of the M300EU is somewhat different from the M300E/EM. Otherwise, the information found in Section 5.4.4 of the M300E/EM Operators Manual (P/N 04288) is applicable to the M300EU.
