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.
