2.6 Alarm Indication on the display
Depending on the type of alarm, the display shows either a symbol or a text when the HP23 detects an alarm
condition:
o Out-of-limits value (defined with the HW4 software for each probe input, includes measured values
and calculated parameter).
o No communication with the probe.
o Display of fixed values when no probe is connected the input. Easily identified humidity and
temperature values can be specified with the HW4 software for each probe input.
o Bad RH sensor or major sensor failure (open or shorted sensor – humidity and temperature)
o Low battery charge
2.7 Real time clock
The HP23 clock keeps track of the date and time and can be adjusted from the keypad. Using the HW4
software, the clock can be synchronized with the PC date and time. The clock does not automatically adjust
for daylight saving time (DST).
2.8 Service connector
The service connector of the HP23 is a USB port. Any standard cable equipped with a mini-USB type
connector at one end can be used to connect the HP23 to a PC running the ROTRONIC HW4 software. See
“Maintenance” for the location of the service connector. The service connector is used for the following:
o Configuration of the HP23
o Downloading data recorded on the HP23
o Access to the HygroClip 2 probe functions
o Firmware updates
3 User configurable settings and functions
The HP23 can be used just as any conventional humidity and temperature indicator. Making use of the HP23
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 HP23 functions and also indicated the factory
default settings.
3.1 Factory default settings
Notes:
o
Configuration of the HP23 and probe by the user and access to its functions requires a PC with the
ROTRONIC HW4 software (version 3.0.0 or higher) installed. A standard USB cable with a mini-USB
connector at one end is used to connect the HP23 service connector to a USB port of the PC.
o
Settings and functions that can also be accessed from the keypad are marked with the letter K (see also
