6.4 4-20 mA, Current Loop Output
The current loop option replaces the voltage output of the instrument with an isolated 4-20 mA
current output. The current outputs come out on the same terminals that were used for voltage
outputs, see Figure 2-2. See Troubleshooting Section 9.3.3 for setup and calibration.
6.5 NO
y
Converter
The NO
y
Converter Option allows placement of the molybdenum converter at the sample inlet
point. This configuration is useful for background studies and where it is desirable to
immediately convert certain components of the atmosphere that decompose rapidly, or may be
lost on the walls of a normal sample induction system. This group of compounds is sometimes
referred to as NO
y
.
The Option consists of a modified M200AU, a M501Y chassis and remote converter. The
pneumatic diagram for this system of components is in Figure 8-7. Because of the nature of this
option, there is a separate manual “M501Y – Remotely Mounted Converter” (P/N 02808). The
manual covers setup, calibration, and operation of the system.
