Instrument Status Parameters

Parameter

Description

Sheath Flow

Volumetric flow rate of the particle free sheath air flow in
liter per minutes.

Sample Flow

Volumetric flow rate of the sample flow, in liter per
minutes. Sample flow plus extraction flow equals the
aerosol inlet flow.

Extraction Flow

Volumetric flow rate of the extraction flow in liter per
minutes.

Charger Flow

Volumetric flow rate of the particle free charger sheath
air in liter per minutes.

Internal Pressure

Absolute pressure in the sizing column in millibar. Used
for the volumetric flow calculation.

Column Voltage 1-3.

Voltage on the center electrode sections in Volt.

Column Voltage 1 = Top Section

Column Voltage 2 = Middle Section

Column Voltage 3 = Bottom Section

Sheath Temp.

Temperature of the particle free sheath air flow in
degree Celsius before it enters the sizing column.

Neg. Charger Current
and Voltage

Ion current of the negative charger in nano Ampere.
Voltage at the charger needle in Volts.

Pos. Charger Current
and Voltage

Ion current of the positive charger in nano Ampere.
Voltage at the charger needle in Volts.

External Inputs

Analog 1

Voltage of the external analog input Analog In CH1 in
Volts.

Analog 2

Voltage of the external analog input Analog In CH2 in
Volts.

Trigger channel 1

Status of the external Trigger IN (On or OFF)

External Outputs

Analog Out

Activates the Analog Output Settings Dialog. The
Analog Out button is only displayed if the Model 3090
EEPS spectrometer has the analog out option.

Note:

The Instrument Status Dialog is inactive while the

Analog Out dialog is displayed.

Controls

Neg. Charger

Use this push button to turn on/off the negative charger.

Pos. Charger

Use this push button to turn on/off the positive charger.

Column Heater

Use this push button to turn on/off the column heater.
Turn the heater on when the instrument is in a cool (i.e.,
air conditioned) environment and sampling from a warm,
humid environment to prevent condensation that could
cause the electrometers to become noisy. Normally, the
heater should be turned off unless needed.

Flow Control

Use this push button to turn on/off the flow control.

Analyzer Voltages

Use this push button to turn on/off the analyzer
voltages.
