4.1 Function overview
MEASUREMENT ACCURACY AND RELIABILITY (PROBE FUNCTIONS)
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 or with the instrument display (if available) and is
shown as Good, SQ-tuned (corrected for drift) or Bad (defective)
Not available when the probe is connected to a HF52
► 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. The data recording function can be use 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 device is powered off, the recording session is
paused but not ended As long as the recording session has
not been ended, the device 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
Not available when the probe is connected to a HF52
MEASUREMENT LOOP VALIDATION
Functions
Description
► Simulator mode
Used to make the HF5 generate fixed values for the humidity,
temperature and calculated parameter. Can be configured,
enabled or disabled
