5.3 Calibrator function
The HP23 can be used to do the following:
o Read the measurement data from a probe, transmitter or other device
o Perform a 1-point or multi-point calibration of the probe, transmitter or other device (humidity and / or
temperature) against a reference HygroClip 2 probe that is also connected to the HP23. The
calibration points are retained in the probe, transmitter or other device memory.
o Perform a 1-point or a multi-point calibration of the probe, transmitter or other device (humidity and /
or temperature) against a known reference environment. The calibration points are retained in the
probe, transmitter or other device memory.
o Adjust the probe, transmitter or other device using the temperature and / or humidity calibration
points already present in the probe, transmitter or other device memory.
5.3.1 Connecting a device to the HP23
The HP23 is compatible with all of the ROTRONIC HygroClip 2 devices (probe, transmitter or other). The table
below explains how to connect the HP23 and the device to be read, calibrated or adjusted.
Device to be read / calibrated Connection to the HP23 Notes
• HygroClip 2 plug-in probe
• Transmitter or other device with
an integral – non removable –
probe. Examples: HF3, HF4
transmitters, etc.
In principle, the probe, transmitter
or other device can be connected
to any of the two HP23 probe
inputs. To avoid confusion, we
recommend to systematically use
probe input 1
Use cable AC2001 to connect a
device with a UART interface (e.g.
service connector) to the HP23
The probe, transmitter or other
device can be calibrated against a
known reference environment or
against a reference probe
connected to the other input of the
HP23
• HygroClip 2 plug-in probe
connected to a device such as
the HF5 (except 2-wire models
such as HF520) or HF8
transmitter
The transmitter (or other device)
must be connected to probe input
1 of the HP23. Do not connect the
device to input 2
Use cable AC2001 to connect the
service connector (UART
interface) of the device to the
HP23
The probe or probes connected to
the device can be calibrated
against a known reference
environment or against a
reference probe connected to
input 2 of the HP23
