DEVICE OVERVIEW
GENERAL OPERATION
SOFTWARE HW4 LITE INSTALLATION
Data analysis and the general setting of the device can be easily done with
the free HW4 Software.
To get the software, download the latest HW4 Software from the Rotronic
Homepage. While the software always remains the same, the corresponding key
unlocks the desired version. For the free Lite version, no key is needed and
up to 3 Rotronic devices can be connected. Probes count as one device.
BATTERY, STAND-BY, AND AUTO-SWITCH
The HP3x has an integrated lithium battery. Simply connect the device to a USB port with the delivered cable to charge it. The device has a stand-by and an auto-switch-off feature. After 5 minutes without user interaction, the display is switched off, after 10 minutes the device is switched off to save battery. This feature does not affect data-logging operations.
DISPLAY AND HOME SCREEN
MASTER RESET
There are a few instances in which the HP3x device may need to be reset.
These include the following:
- To restore to factory default settings.
- The HP3x is not functioning properly (value are frozen).
Performing a reset will erase user data. Performing a Master Reset: Press and hold the reset button on the backside of the device with a thin pen or an office clammy for 3 sec.

UNITS
Main menu [OK]→Settings→Units
Your options are as follow:
- Distance: m, ft
- Temperature: °C, °F
- Pressure: hPa, mmHg
- Weight: kg, lbs
CALCULATED PSYCHROMETRIC PARAMETERS
Besides relative humidity and temperature, the HP32 can display 2 of the
following 10 psychrometric parameters:
- Dew / Frost point (Dp/Fp)
- Wet-bulb temperature (Tw)
- Enthalpy (H)
- Vapor concentration (DV)
- Specific humidity (Q)
- Mixing ration by weight (R)
- Vapor pressure (E)
- Saturation vapor pressure (Ew)
- Saturation vapor density (SVD)
Select the parameters that you want to log and/or see on the home screen
within:
Main menu [OK]→Settings→Displayed calculated parameters
You can change the order of values on the home screen by [UP] on the home screen.
You can change the atmospheric pressure constant used in calculations in:
Main menu→Settings→Atmospheric pressure
SAVING DATA
HOLD/CAPTURE AND SPOT MEASUREMENTS
Freeze the displayed values on the home screen by pressing the
[Hold/Capture] action button on the home screen. Those values can then be:
- Saved as a spot measurement with [Capture]
- Released again with [Release]
DATA LOGGING
Program or start the automatic logging at regular intervals with the [Log] action button. Define the storage location, the interval, and, if you want, a start and stop time, then start the logging operation by pressing the [Start] action button.
Your device will be automatically switched on at the given start time to start the logging.
The main menu is not accessible while data logging is active. Spot measurements are, however, still possible.
You must name storage locations before use. Simply use the [Rename] action button when selecting a storage location to assign it a name.
VIEWING SAVED DATA
SPOT MEASUREMENTS
Review the spot measurements by selecting their storage location within:
Main Menu [OK]→Memory →Capture
LOGGED DATA
Review the logged data by selecting its storage location within:
Main Menu [OK]→Memory→Log
Switch between graphic displays and MIN / MAX / AVG values of the 4
parameters with [UP] and [DOWN].
ALARM
Set up upper, lower limits as well as hysteresis for every displayed parameter
in:
Main Menu [OK]→Alarms
Broken alarm limits are shown in red on the home screen.
To enable an acoustic signal for an alarm:
Main Menu [OK]→Settings→Buzzer
ADJUSTMENT
The HP3X has a humidity and temperature adjustment function so that you can
adjust directly with the handheld instrument. The instrument can make a
1-point adjustment for temperature and a 1-point or 3-point adjustment for
humidity.
Main Menu [OK]→Adjustment
Select Humidity or Temperature with the arrow keys and confirm with OK.
Example of sequence for 3-point humidity adjustment:
Reference value 1 10 %rh
Reference value 2 35 %rh
Reference value 3 80 %rh
The value of the reference can be entered with the keypad. The attached probe
shows the current measured value. After entering the first reference value (10
%rh), press OK to confirm
“Save & Continue” and enter the next reference value (35 %rh).
When all three reference values have been entered, press OK to confirm “Save &
Continue” again, and adjustment is finished. The last adjustment date is now
listed under Adjustment.
