Microbarograph. ADC is Quanterra model QX80.

DIGITAL FORMAT:
24 bit integer data words for all broad-band (20 sps), long period (1 sps), very  
long period (0.1 sps) and ultra long period (0.01 sps) channels.  Range: 
+8,388,607 to -8,388,608 counts.  16 bit integer data words for very short period
(100 sps), mass position, and all environmental channels.  Range: +32767 to -32768.

EVENT DETECTOR ALGORITHIM:  
The Murdock event detector (Murdock 1983) was installed on 03 May 1983.

The Noise Study was done using 1992 data, consequently, it is only an estimation for this generation of station instrumentation.
COMMENTS:  The 54000 is installed with a non-standard orientation.  The
orientation portion of the SEED channel names change from N and E to 1 and 2
(e.g. BHN changes to BH1) and vice-versa. Please see the latest dataless seed 
volume for current information or contact the Albuquerque Seismic Lab.
