4 User configurable settings and functions
The HC2 probe ships configured as per the factory defaults:
o
Users who intend to use the probe as a stand-alone analog device can use the probe as any conventional
humidity and temperature probe. A connecting cable with active electronics may be required to power the
probe. Most such users will never have to use the probe configurable settings and functions
o
Users who purchased a probe for use with another ROTRONIC instrument can also use the probe right
away and do not necessarily have to use the probe configurable settings and functions
o Users that intend to use the probe as a stand-alone digital device typically need to use a connecting cable
with active electronics and generally need to configure either the probe or the PC
Making use of the probe configurable settings and functions is entirely up to the user and the appropriate settings
depend on the user application. We have provided below a short description of the probe functions and also
indicated the factory default settings.
4.1 Function overview
MEASUREMENT ACCURACY AND RELIABILITY
AirChip 3000 Functions Description
► Humidity / temperature adjustment
o
1-point or multi-point humidity calibration or adjustment
o
1-point or 2-point temperature calibration or adjustment
o
Generate a time stamp for calibrations and adjustments
o
Retain and view last adjustment date and adjustment values
o
Generate calibration and adjustment protocols
► Automatic humidity sensor test
and optional drift compensation Tests the humidity sensor for drift caused by contaminants and
can be used to automatically apply a correction. The test is
automatically carried out at regular intervals of time. Can be
configured, enabled, or disabled
The humidity sensor status can be verified either with the HW4
software and is shown as Good, SQ-tuned (corrected for drift) or
Bad (defective)
► Data recording The data recording function differs from a true data logging
function in the sense that the AirChip 3000 does not time stamp
the data. This data recording function can be used to investigate
events such as a sensor malfunction as well as to retrieve data
that would otherwise be lost
o
Start or stop data recording - up to 2000 value pairs (%RH
and temperature). Starting a recording session erases all
previously recorded data
o
The recording mode and log interval can be specified
o When the probe is powered off, the recording session is
paused but not ended As long as the recording session has
not been ended, the probe automatically resumes recording
data when powered up again
o
The recorded data can be downloaded to a PC with the
HW4 software, time stamped and viewed
