2.1 PROBE
The HP32 is compatible with all HC2 and HC2A probes. Simply connect it to the probe input
on top.
A calibration of the HP32 after changing the probe is not necessary.
2.2 TRIPOD SOCKET
The standardized tripod socket (1/4"-20 UNC thread) at the back of the device enables a wide
range of conventional mounting accessories. For example, camera tripods or, the belt buckle
delivered with the device.
2.3 MAGNETIC
The magnet integrated at the back of the HP32 enables easy installation on metallic surfaces
such as, for example, ventilation shafts.
The magnetic fastening will not work with an accessory mounted on the tripod socket.
2.4 LANYARD
Delivered with the HP32, you will find a lanyard that can be tightened on the HP32 for easy
hand carrying and manipulation.

GENERAL OPERATION

3.1 BATTERY, STAND-BY AND AUTO SWITCH OFF

The HP32 has an integrated battery. Simply connect the device to an USB port with the deliv-
ered cable to charge it.
The device has a stand-by and an auto switch off feature. After 5 minutes without user interac-
tion, the display is dimmed. Moreover, after a total of 10 minutes without user interaction, the
device is switched off to save battery.
These features do not affect data logging operations. While data logging is active,
although the screen is dimmed or off, data points are still logged and saved.

4.1 LANGUAGE
To change the display language, go into:
Main menu [OK]  Settings  Language
Available languages: English, Deutsch, Français, Italiano

4.2 DATE/TIME

To set up the date and time, go into:
Main menu [OK]  Settings  Date / Time
The following settings can also be set beside the date and time.
• Date format: DIN, US, ISO
• Time format: 12 h, 24 h
The date and time must be set correctly for proper operation of the device.

4.3 UNITS

Set units used and displayed by the HP32 into:
Main menu [OK]  Settings  Units
Your options are as follow:
• Distance: m, ft
• Temperature: °C, °F
• Pressure: hPa, mmHg
• Weight: kg, lbs

4.4 CALCULATED PSYCHROMETRIC PARAMETERS

Beside relative humidity and temperature, the HP32 can display 2 of the following 10 psychro-
metric 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
5 SAVING DATA
5.1 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]
5.2 DATA LOGGING
Program or start the automatic logging at regular interval 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.
6 VIEWING SAVED DATA
6.1 SPOT MEASUREMENTS
Review the spot measurements by selecting their storage location within:
Main Menu [OK]  Memory – Capture
6.2 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].
7 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.
You can also enable an acoustic signal for broken alarms in:
Main Menu [OK]  Settings  Buzzer
8 ADJUSTEMENT
Adjustments of the probe (humidity and temperature) can be performed in:
Main Menu [OK]  Adjustement
Incorrectly adjusted probes will deliver wrong measurements. Please refer to our man-
ual for more information about probe adjustments.
9 COMPUTER CONNECTION
It is possible to connect the HP32 to a computer with the delivered USB service cable. Data
analysis and settings changes are performed with the HW4 software for which you received a
license key.
