5.2 Interaction between the HygroLab C1 and HygroClip 2 probe
It is important to note that when used together, the HygroLab C1 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 HygroLab C1 indicator and HygroClip 2 probe (HC2) operate together as
indicated below:
Function / Setting

HC2 Notes
Device protection X X Individual to the HygroLab C1 and HC2 probe
RS-485 address X X Individual to the HygroLab C1 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 HygroLab C1 Input Name
Calculation X X
Psychrometric calculation
HygroLab C1 setting overrides HC2 probe setting
Simulator function X X
Generates fixed humidity and / or temperature value
When enabled, the HygroLab C1 settings override the HC2
probe settings
Unit system X X
The HygroLab C1 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 HygroLab C1 and probe.
Out-of-limits value
alarm
X X
The HygroLab C1 settings are independent from the HC2
probe settings.
The HC2 probe settings have no effect on the HygroLab C1
and out-of-limits values defined at the probe level do not
generate a HygroLab C1 alarm.
5.3 User defined parameter
Using the HW4 software, the HygroLab C1 can be enabled to calculate for each probe input a user defined
parameter such as the difference between the temperature and the dew point measured by a probe, the
average of the temperature measured by two probes, etc.
The user defined parameters can be shown on the display by turning on the Formula option (HygroLab C1
internal menu - accessed from the keypad). For additional explanations and instructions see the following
HW4 manual: E-M-HW4v3-F2-019.
