D Record

D records contain the following information:

 

 

 

D

 

Record identifier

 

 

 

 

 

 

 

 

 

 

 

Date

 

Date in yyyy/mm/dd format

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Time

 

Time in hh:mm:ss format

 

 

 

 

 

 

 

 

 

 

Flags

 

Status Flags (see information in RIE command description)

 

 

 

 

Conc

 

Aggregated concentration calculated by dividing the

 

 

 

 

 

 

 

 

accumulated aggregate counts by the live-time of the

 

 

 

 

 

 

 

 

sample flow rate (2 cm3/sec). The aggregated counts and

 

 

 

 

 

 

 

live-times are accumulated each 1/10th second interval.

 

 

 

 

 

 

 

 

The overflow flag is set when the concentration value

 

 

 

 

 

 

 

 

exceeds the maximum specified concentration.

 

 

 

 

 

 

 

AT

 

Elapsed sample time 0.1 sec resolution (0.1 to 3600)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

LT

 

Live time 0.001 sec resolution (0.001 to 3600)

 

 

 

 

 

 

 

CNT

 

Accumulated particle counts

 

 

 

 

 

 

 

 

 

 

Photo

 

Average photo-detector value in mV

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Reserved

 

Blank reserved space

 

 

 

 

 

 

 

 

 

 

 

PH

 

Average pulse height in mV

 

 

 

 

 

 

 

 

 

 

PSTD

 

Pulse height standard deviation
