11.5. SUBSYSTEM CHECHOUT

11.5.1. RELAY BOARD

The information found in Section 11.5.5 of the M300E/EM Operators Manual (P/N 04288) is applicable to the M300EU with the following exception:

•The following table replaces Table 11-8 of the M300E/EM Operators Manual.

11.5.2. MOTHERBOARD

11.5.2.1. A/D Functions

The M300EU makes higher resolution CO measurements than the M300E/EM means that it is susceptible to temperature coefficient issues related to the motherboard’s A-to-D converter that could occur if the temperature of the motherboard differs significantly from that of the rest of the analyzer’s oven area.

•Compare the values of the BOX TEMP & OVEN TEMP test functions. If they are significantly different check the function of the:

•Oven theaters.

•The oven heater fans.

•The motherboard stabilization fan.

•The relays controlling the oven heaters.

•No abnormal blockages to airflow inside the oven area exist.
