5-52 Electrostatic Classifier Model 3082 and SMPS Spectrometer Model 3938
A u t o R e c o v e r y F e a t u r e
If the classifier is sampling in SMPS mode and a power failure occurs,
sampling will resume when power returns.
For auto recovery to occur, the following must be true:

The classifier must be in SMPS mode, not in external control mode
using the Aerosol Instrument Manager software.

A sample must be in progress when power failure occurs.

Power must return to both the classifier and detector.

The classifier must still be connected to the detector when power
returns.
If these conditions
are met, upon power-
on, the following
screen will appear:
Most settings are preserved after auto recovery. The behavior of the
instrument after auto recovery is detailed below:

All scan parameters (hardware settings, gas parameters, scan time,
etc.) are preserved after auto-recovery.

Sample and scan indices restart at 1 when sampling resumes.

Sample data will be saved to a new text file when sampling resumes.

Sampling will resume immediately after power returns. Auto recovery
does not take into account a delayed start time.

Text in the Notes field will be replaced with the text “Recovered from
power failure.” This text will stay in the notes field until it is overwritten
by the user or until the next power cycle.

Graph viewing settings such as units, weights, and view boundaries
may not be preserved after auto-recovery.
If you discover that your instrument has recovered from a power failure, it
is recommended that you stop sampling in ord
er to clear the “Recovered
from power fai
lure” text from the Notes field.
Note : Sample records immediately following an auto-recovery will often
contain errors due to the stabilization and warm-up times required
by the system.
