3.2 Interaction between the HP23 and HygroClip 2 probe functions
It is important to note that when used together, the HP23 indicator and HC2 probe (HygroClip 2) constitute a
2-component system. Each system component has its own microprocessor, firmware and functions. Some of
these functions are unique to each system component. Other functions are found in both components.
The functions and settings of the HP23 indicator and HygroClip 2 probe (HC2) operate together as indicated
below:
Function / Setting HP23 HC2 Notes
Device protection X X Individual to the HP23 and HC2 probe
RS-485 address X X Individual to the HP23 and HC2 probe
Device Name X X
User defined description
The device name of the HC2 probe is not displayed by HW4 and is
replaced with the HP23 Input Name
Calculation X X
Psychrometric calculation
HP23 setting overrides HC2 probe setting
Data refresh rate X
Refresh interval for the LC display. When set above 1 s, this
setting causes the HC2 probe not to be powered in between
display refreshes so as to conserve battery power.
Note: when the HP23 is recording data, the probe is powered as
required by the log interval, regardless of the display refresh
interval.
Simulator function X X
Generates fixed humidity and / or temperature value
When enabled, the HP23 settings override the HC2 probe settings
Unit system X X
The HP23 setting overrides HC2 probe setting. The HC2 probe
settings still apply when the probe is used alone
Make sure to use the same humidity symbol and the same
temperature unit for both the HP23 and probe.
Out-of-limits value
alarm
X X
The HP23 settings are independent from the HC2 probe settings.
The HC2 probe settings have no effect on the HP23 and out-of-
limits values defined at the probe level do not generate a HP23
alarm.
RH sensor test X
The RH sensor is not tested when the refresh interval for the LC
display is set above 1 sec.
Analog outputs X
Parameter and scale
The HC2 probe settings have no effect on the HP23
