Page 6: Chapter I. Instrument Introduction
Chapter I. Instrument Introduction Model 3991 is a linear digital aerosol photometer for scattered light with advanced technology and scientific design, and serves as the optimum test instrument for testing the integrity of the high efficiency particulate air (HEPA) filter or conducting leakage test. Considering the low concentration of atmospheric dust in the upstream of the HEPA filter under test, the aerosol generator should be used to replenish and generate dust to meet the test conditions. -

Page 12: Test Connection At The Upstream (High Aerosol Concentration Zone)
Attention Before testing, the operator should check the sampling joint and ensure that there are no fluffs or impurities blocking the filter screen. During the test, if the pump noise suddenly increases, the operator should check of the gas passage is blocked, especially the filter screen at the sampling joint. It’s recommended to wipe clean the filter screen at the sampling with a piece of silk cloth before each use. -
Page 13: Test Connection At The Downstream (Low Aerosol Concentration Zone)
In order to ensure the accuracy of the test results, the upstream and downstream sampling air pipe should not be mixed. 3.1-3 Test Connection at the downstream (low aerosol concentration zone) Attention 1) Be sure to connect the probe’s cable connector before the instrument is powered on. -
Page 14: Loading Printing Paper Into The Printer
3.2 Loading printing paper into the printer Please use the printing paper that is matched with the printer, the printing paper’s specifications should be 57mm (2 in) in width. If the printing test results need to be saved for a long run, please choose the long-term thermal o-sensitive printing paper. -
