Troubleshooting

General Questions

Fault

Possible Cause

Remedy

Very low or no instrument 
response detected, yet com-
pounds are known to be pre-
sent

The Multi-PID 2 has not been 
properl

Verify the concentration of 
the span gas. Calibrate the 
Multi-PID 2. See page 73.

Memory slots are not set up 
correctly.

Program the memory slots. 
See page 67.

Response Factor has been 
set to zero. 

 Set Response Factor to 1.0 
or refer to Table 6 for correct 
response factor.

Detector is leaking.

Ensure the UV lamp is cor-
rectly installed.

Ensure the lamp cover is 
tight. Do not over tighten.

Ensure the O-ring seal on the 
lamp cover is positioned cor-
rectly.

UV lamp is the incorrect size.  Contact Dräger Safety for 

correct lamp.

Sampling environment is 
extremely humid or it is rai-
ning.

Water vapor is not ionized by 
the PID. Water vapor does 
scatter and absorb light that 
causes a higher or lower rea-
ding. The Multi-PID 2 has 
been designed to work in a 
humid environment but you 
may notice a decreased 
response.

UV lamp is failing.

Install a new UV lamp. See 
page 80.

High concentrations of non-
ionizable compounds.

Chemical compounds with 
an ionization potential higher 
than 10.6 eV or 11.7 eV scat-
ter and absorb UV light. Sen-
sitivity may be decreased. 
Contact Dräger Safety for 
more information.
