C-8 Electrostatic Classifier Model 3082 and SMPS Spectrometer Model 3938
Table C-2
Electrostatic Classifier Firmware Commands List (select)
RMDETERRORS returns the detector errors.
Example: RMDETERRORS returns a 32 bit integer. If the bit is set, there
is an error.
Water separator temperature
Read SMPS
Counts/Deadtime
During Scan
RMSCANDATA reads the SMPS counts and deadtime during scan.
Example: RMSCANDATA returns a string yyyy/mm/dd
hh:mm:ss,df,cf,pol,ndata,eos where yyyy = year, mm = month, dd = day,
hh = hour, mm = minutes, ss = seconds, df = detector error, cf =
classifier error, pol = polarity, ndata = number of data points following
this header, eos = end of scan flag
Data point format is ParticleCounts,Deadtime in microseconds
RMIMPFLOW reads flow rate as measured by the dP sensor across the
impactor. Only valid if 3082-compatible impactor is installed.
Sets the time using the format hh:mm:ss
Example: WDTIME 15:01:00 sets the time to 3:01 pm and returns OK
Sets the date using the format mm/dd/yyyy
Example: WDDATE 07122013 sets the date to July 12
th
, 2013 and
returns OK
Write High
Voltage Polarity
WSHVPOL sets the high voltage polarity.
Example: WSHVPOL returns the values 0 or 1, where 0 = negative
voltage, and 1 = positive voltage
Write Sheath
Voltage Setpoint
WSSHFLOW Sets the sheath flow rate in L/m.
Example: WSSHFLOW returns a value in the range 0.0 to 30.0 in L/min
WSHV Sets the DMA high voltage in volts.
Example: WSHV returns values in the range 0.0 to 10000.0 L/min
Write Detector
Inlet Flow
WSDETINFLOW Sets the detector flow rate to low or high.
Example: WSDETINFLOW returns values where 0 = low flow and 1 =
high flow.
Write Tube
Length Between
Classifier and
detector
WSTUBELENGTH sets the tube length from 0.1 to 100 centimeters
Example: WSTUBELENGTH 25 sets the length to 25 centimeters
