HGSUM Mercury Lamp Summary
HGSUM reads the daily Data (B) file and prints out the 'summary' results of the day's HG
calibrations. In addition an entry is made in the HGOAVG.nnn file.
The HGSUM command is usually invoked as part of the ED command.
See also Appendix A for an explanation of the HGOAVG.nnn file.
HGSUM is an 'Ozone Only' command, and will not execute in the NO
HV
High Voltage Test
The HV command invokes a test used to determine the optimum high voltage setting for the
photomultiplier. The HVSET command can then be used to set the High Voltage.
This test is normally used in the factory during the final set-up stages of manufacture, or in
the field if it is suspected that the setting is not correct.
The Standard Lamp is turned on, the iris is opened, FW#1 is put to position 1, and FW#2 is
set to position 0.
See the HVSET command, and Appendix F for more details on the HV test.
HVSET High Voltage Set-up
The HVSET command can be used to adjust for the optimum High Voltage as determined be
the HV test.

Change Instrument
The NO command allows the instrument number of the Brewer to be changed. Each Brewer
has a set of files which are stored in the C:\BDATA\NNN subdirectory, and which are
necessary for proper operation of Brewer NNN. When the NO command is issued, the
software is made aware of which Brewer is connected.
NOSUM NO2 Summary
The NOSUM command reads the BJJJYY.nnn file and produces NO2 DS and ZS
summaries and statistics for the day's observations. An entry is made in the NONAVG.nnn
file. This command is usually invoked as part of the ED command.
NR
No Recording
This command will turn off recording to the data disk. Data will continue to be printed to the
