Sheath Flow Temperature Too Low
Check that flowmeter connector did not come loose during
shipping.
The flowmeter is reading outside its valid range of -10°C to
70°C. If the instrument is in a hot location, move it to a cooler
location. If not, the flowmeter may be defective.
The flowmeter is reading outside its valid range of -10°C to
70°C. If the instrument is in a cold location, move it to a
warmer location. If not, the flowmeter, its cable or connector
may be defective.

Positive Charger Current Too Low
Check the state of the Chargers
in the instrument’s User
Settings Window or view the Instrument Status window in the
EEPS software.
Check state of Flows in the instrument’s User Settings Window
or view the Instrument Status window in the EEPS software.
Chargers are turned off automatically when flows are turned
off.
The charger current is not stable or has hit a voltage limit to
meet the required current. Clean the charger assembly and
clean or replace the charger corona wire.

34
Particle Concentration Too High
The concentration on one or more channels has exceeded its
upper limit. Lower the concentration of aerosol going into the
instrument. This is indicated in the software by a red box on
top of the column that is over-ranged in the 2D histogram.
34
Particle Concentration Too High
The RMS noise for a single channel is much larger than the
average of all the other channels. This could indicate that the
column is dirty. Clean the column or contact TSI.
50
Electrometer Channel High Offset
During instrument zeroing, the offset current for one or more
channels was higher than normal. This could indicate that the
column is dirty. View the last offset and RMS values to
determine the channel causing the error. If the channel is not
changing over time, the instrument may be okay to continue to
use. Otherwise, clean the column or contact TSI.
54
Electrometer Channel Noisy
During instrument zeroing, the RMS noise for one or more
channels was higher than normal. This could indicate that the
column is dirty. View the last offset and RMS values to
determine the channel causing the error. If the channel is not
changing over time, the instrument may be okay to continue to
use. Otherwise, clean the column or contact TSI.
