Maintenance 

 

Overview 

The N95-Companion and P

ORTA

C

OUNT

 Plus both require daily and periodic 

maintenance. Refer to the P

ORTA

C

OUNT

 Plus Operation and Service Manual 

for P

ORTA

C

OUNT

 Plus maintenance information. The N95-Companion 

maintenance information appears below.  
 

Daily Checks 

The daily checks are designed to determine if the instrument is working 
properly. They must be done in the order specified. There are four daily 
checks:  

 

Particle check 

 

Classifier check 

 

Zero check 

 

Maximum fit factor check 

Note

FitPlus for Windows software can be used to automate the daily 
checks if desired.  

 

Performing the Particle Check 

After you set up the N95-Companion and P

ORTA

C

OUNT

 Plus, run 

the particle generator for at least 15 minutes, touch the count switch 
on the P

ORTA

C

OUNT

 Plus. The concentration number will appear in 

the P

ORTA

C

OUNT

 Plus display. You must have a particle count of at 

least 70 to pass this test.  
 

Note: 

The N95-Companion will not operate at concentrations 
below 70 particles per cc. Do not be concerned if 
concentrations are higher than 250 to 300 particles/cc. This 
may simply indicate a high concentration of naturally 
occurring aerosol. Also, if concentrations are this high, you 
may be able to operate the particle generator at a lower 
setting, or not at all. Refer to the Model 8026 Particle 
Generator Operation and Service Manual for more 
information.
