4 Function Overview 4
4 Function Overview
The UVpad E combines the benefits of the spectral measuring technology with a handheld and
easy to operate radio meter. Use the spect roradiometer UVpad E for an accurate meas urement
of the UV irradiance and for comparisons of different UV lamps and UV LEDs. 512 photodiodes measure the spectrum in the wavelength range of 200 – 440 nm. The categorization in
UVA, UVB and UVC is taken according to international standards and traceable. The calibration to only one light source is omitted.
During the measurement, the spectrum is shown on the graphic display. The irradiances for
UVA, UVB, UVC and VIS are available by the click of a button. In the background, the spectrum is already record ed. Whi le measuri ng, the do se an d the ch ronolo gical i rradian ce seq uence
can additionally be documented. Spectra and measurement data can be exported and evaluated
with the provided software.
The UVpad E offers these functions/features:
Spectral measurements:
• Real-time of the spectrum
• Real-time of irradiance
Radiometric measurements:
• Spectrum at max irradiance
• Irradiance (UVA, UVB, UVC, VIS)
• Profile of irradiance (UVA, UVB, UVC, VIS)
• Dose of irradiance (UVA, UVB, UVC, VIS)
Measurements related to cau se and eff ect s:
• Photo initiator spectrums (optional)
• Sensitivity functions of broadband radiometers (optional)

6 Intended Use
The UVpad E determines the irradiance in the UV and VIS spectral range and indicates
these on the integ r ated display. Typic al Applic ati ons:
- Measurement of UV-LEDs and ultraviol et lamps
- UV dose measureme nt s
- Universal irrad iance measurement
- GMP and IQ/OQ docum ent ation
7 Conventional Use
The UVpad E is solely intended for the determination and visualization of irradiances, which are
generated in UV curing systems.
The UVpa d E is battery operated and suitable for usage with lithium batteries, type CR2032. In
case other batteries, than the supplied ones, are used, an operating range of up to 70 °C has to be
observed. Spare batteries are to be obtained from your supplier.
Operation only allowed in dry environments. The assembly position is arbitrary.
When using the UVp ad E, light and UV radiation can be reflected and distributed at the housing.
Appropriate protection measures for the protection against radiation need to be applied, if necessary. Note: The UVpad E itself does not emit any hazardous radiation.
The housing, with the exception of the battery compartment, must not be opened by the user.
The optically active surface must not be touched.
Gloves need to be worn when cleaning the optically active surface.
The UVpad E is a highly sensitive optical measurement device. It must not be exposed to shocks.
Any other usage than the one described above leads to a damage of the product. Furthermore, this
involves risks, such as short-circuits, fire and electric shocks. The entire device must not be modified and/or remodeled! The safety indications are to be observed without fail.

When using the UVpad E, light and UV radiation can be reflected and distributed

The maximum housing temperature of the sensor can re ach > 60 °C and there
is the risk of skin burns on contact. Please allow for the UVpad E

9 Operation
The UVpad E is operated via four keys. These are arranged on the front panel below the display. The keys and the functions are illustrated as follows:
The keys and are addit ionally available as softke ys. Softkey functions are directly dis-
played above the key. Example:
9.1 Switching the device on and off
The UVpad E is activated via any key. During the initialization (ca. 2s), the welcome screen is
displayed:
After the initialization, the standby menu is displayed:

, the device switches off
In this example, the language “English” is set.
In the standby menu, the UVpad E is switched off via the key .
After 2 minutes of not using the UVpad E
automatically.
9.2 Standby Menu
Via the standby menu, all functions of the UVpad E are available for you. These are:
• Start measurement
• Show last measurement
• Scope measurement
• Settings
• Information
In the standby menu and in all other menus, select the active menu item via the keys and .
Confirm the active menu item with the key . With , you return to the previous menu with-
out saving any changes.
The selected menu item is highlighted in black and displayed inverted. If several settings are
selectable, then the selected setting is marked with. Example:
“German” is selected, but not set.
With the key -key, the setting is accepted
and the language is being changed.

Use ‘”Auto” mode to get the best integration
time or, in fixed mode use and ke ys to
adjust integration time.
Notes:
The optimal integration time, gain (L/H) and the saturation of the measurement range are displayed at the upper display edge. The integration time is displayed in ms. Example:
T 100: The integration time is 100 ms
Hint:
For optimum measurement results, the measuring range should be fully controlled. Very good measuring results are achieved when the measuring range
is at least 50%.
The modulation is linear to the set integration time. Example:
55/5000
T10 M20%: Measuring range is 20% used => Bad
T40 M80%: Measuring range is 80% used => Very good

Stop the measurement by pressing the key for at least 0.5s.
The measurement results are displayed automatically. For a better overview, these are partitioned to four screens.
1. Irradiance (only when viewing saved measurements)
2. Dose of irradiance (UVA, UVB, UVC, VIS)
3. Spectrum at maximum irradiance (only when viewing saved measurements)
4. Irradiance profile over the duration of the measurement
These can be displayed with the keys or .

Note:
If the irradiance is too low for the measurement range, then the UVpad E displays no measured values. The irradiance and the dosage values are then di splayed with “-“.
UVA, UVB, UVC, VIS and total are displayed.
