Page 9: Summary Of System Design
Summary of System Design Overview and Theory The WMA-5 is designed to function as a self-contained instrument for continuous measurement of CO air. Its open-path design allows for continuous, unattended air sampling, as the pump introduces fresh sample gas to the essential component, the IRGA (infrared gas analyzer). - Page 10 Some changes may require recalibration, although one of the strengths of the WMA-5 is that recalibration is not a routine (annual) maintenance task as a result of our innovative “Auto-Zero” function. Our Auto-Zero function corrects for nearly all changes that result in calibration drifts.

Input: 12 VDC, 1.5A or 100-240 VAC, 50-60 Hz, 0.6A (AC adapter included) The WMA-5 can be powered by 12V if required via direct connection to the terminal block. It requires a 12V DC input at 1.5A. Connect the positive to +12V and the negative to GND. The terminal block is clearly marked for ease of connection. -

Data Port Touch Display The WMA-5 features a 2.7” a-Si, active matrix TFT, Electronic Paper Display (EPD) touch panel. The panel has such high resolution (117 dpi) that it is able to easily display fine patterns. Due to its bi-stable nature, the EPD panel requires very little power to update and needs no power to maintain an image. -
