Making use of the HygroMet MP and HC2-S3 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 HygroMet MP and HC2-S3 and probe functions and also indicated the factory default settings.
4.1 Requirements for configuring the HygroMet MP
Configuration of the HygroMet MP by the user and access to its functions requires the following:
o
PC with the ROTRONIC HW4 software (version 2.3.0 or higher) installed.
o Service cable AC3006 to connect the HygroMet internal service connector to a USB port of the PC.
o DC voltage source to power the HygroMet MP
Note: The RS-485 interface of the HygroMet MP 3-wire version can be used as an alternative to the service
connector to configure the HygroMet MP after connecting the HygroMet MP to a RS-485 network monitored
by a PC with the HW4 software.
4.2 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 HygroMet
2-wire version
► 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 HygroMet
2-wire version
