Access Door: To provide access to the Micro-Fuel Cell, the front panel swings open when the latch in the upper right corner of the panel is pressed all the way in with a narrow gauge tool. Accessing the main circuit board requires unfastening the rear panel screws and sliding the unit out of the case.

1.6Recognizing Difference Between LCD &

VFD

LCD has GREEN background with BLACK characters. VFD has DARK background with GREEN characters. In the case of VFD - NO CONTRAST ADJUSTMENT IS NEEDED.

1.7Rear Panel (Equipment Interface)

The rear panel, shown in Figure 1-2, contains the gas and electrical connectors for external inlets and outlets. The Zero and Span gas connectors, and the Current signal outputs are optional and may not appear on your instrument. The connectors are described briefly here and in detail in the Installation chapter of this manual.
