testo 6610
- 2.2 Product description 95
Temperature error as a factor of process temperature and temperature of
electronics
2.2.6 testo 6615 trace humidity cable probe
(self-adjustment)
The testo 6615 probe corrects deviations in measurements by means of self-
adjustment. This has a particular significance with low humidity values (in
dewpoint range).
Please also see volume 1, chapter 1.3.3.6 for the functional
principle of the testo 6615.
Only use testo 6615 with sintered PTFE filter (art. no.
0554 0759) or sintered stainless steel filter (art. no.
0554 0647).
During the self-adjustment phase the signal values of the
analog outputs remain on hold, meaning they are frozen for
the duration.
System error 6681 + probe, electronics 25 °C/+77 °F
System error 6681 + probe, electronics -25 °C to +70 °C/-13 to +158 °F
