Description
The UV measuring device KUV2.4 WR MD is used in conjunction with UV sensors of
various types as a mobile handheld device for checking ballast water UV systems.
The display range of this device has been extended upwards for strong medium
pressure lamps.
By comparing the measured values between the system sensor and the UV sensor of
the device, it can be determined whether the system sensor needs to be
recalibrated or replaced. In addition, with this device, digital system sensors can be
programmed on site and recalibrated in the range of ± 30%.
A robust metal housing with degree of protection IP65 protects the device from
external influences. It is powered by rechargeable batteries, has an LCD display with
backlight, automatic measuring range switching and is easy to operate using three
buttons. It is possible to supply / charge via a plug-in power supply and to connect a
data logger or a computer. The delivery takes place in the transport case.

Commissioning
The device must be charged before commissioning. To do this, the round plug of the power supply unit must be
inserted into the appropriately labelled hollow socket in the battery/connection compartment at the bottom of the
device. The flap of the connection compartment can be easily opened by pushing against the hinge from behind. A
green LED next to the plug lights up during charging. The device can be charged and operated at the same time.
Before switching on the KUV2.4WR MD, the sensors must be connected to the top connectors of the device. The
reference sensor is connected to the right M12 connector, the digital sensor to be calibrated (option Z4) is connected
to the left M12 socket using the supplied extension cable. It must be ensured that sensors of the same type are always
compared/calibrated (e.g. DVG40°). The device must be switched off each time the sensor is changed. It is switched on
by briefly pressing the red button. Pressing this button for a longer time switches the device off again.
After switching on, the software version number appears on the display. The device then automatically recognizes the
connected reference sensor, takes its calibration values from its memory and carries out an automatic zero-point
adjustment. If no sensor, a defective sensor (cable break) or a sensor not registered in the device is connected to the
device, the error message invalid sensor is issued. The serial numbers of the sensors registered in the device can be
found on the back of the device. During the automatic zero-point adjustment the display shows zero check wait…. The
reference sensor must not be exposed to UV radiation during this time! Ambient light does not affect the adjustment
since the UV sensors are blind to daylight. After the zero-point adjustment, the type of the connected reference
sensor is displayed, e.g. reference sensor DVGW W294 40/160°. The device then scans the digital system sensor
connected to the left socket while scan bus… is displayed. If no sensor is connected, the message no sensor <return>
appears, which must be acknowledged with the red button. After the start routine has ended, the device
automatically switches to measuring mode.
Measurement
The first line now shows the value of the connected reference sensor, R: 0,000 W/m². The second line shows the
current measured value of the system sensor, S: 0,000 W/m². If no system sensor is connected, the message S:
inval.sens.. In the entire measuring range from 1 to 20000 W/m², the system automatically switches to the optimal
measuring range. A hysteresis function with time delay prevents constant range switching at irradiance levels near the
switching points. The displayed value refers to the underlying standard of the connected reference sensor. The menu
item lamp type can be used to choose between low pressure (standard after switching on) and medium pressure.
Accordingly, either the calibration value for LP lamps at 253.7 nm or the value of the medium pressure calibration is
loaded from the internal memory. The latter is indicated in measurement mode by md before the value of the
irradiance. Via the menu item uv irrad. unit can also be selected between W/m², mW/cm² and µW/cm² if required.
The device converts the display values.
Under unfavorable lighting conditions, the display lighting can be switched on and off if necessary, by pressing the
blue button (LIGHT). To increase the operating time on battery power, the display lighting switches itself off after
approx. 1 min. To protect the batteries, the device also has an economy circuit that switches the device off 10 minutes
after the last key was pressed. This function can be deactivated via the menu for longer series of measurements.
When the batteries are discharged, low bat flashes in the upper display line alternately with the sensor measured
value. If the lighting is used frequently or long series of measurements, mains operation should be preferred. The
enclosed plug-in power supply can be connected via the correspondingly marked hollow socket after opening the
connection compartment flap. Attention: with the bottom flap open, the device no longer corresponds to IP65!
The last measured value can be saved using the yellow button (HOLD). A hold is then shown in the display alternating
with the saved measured value. Pressing this button again returns to the current measurement. A maximum value
function is also available. This is called up in measurement mode by long pressing the yellow key (HOLD). A max will
then appear in the display alternating with the maximum value. The maximum value can also be reset via the menu.
The same happens when switching off or when changing a sensor.

Measurement output
An analogue and digital interface are available for the measured value output. The analogue output is designed as a
voltage output of 0.1 to 4.1 V for each measuring range. 0.1 V corresponds to 0 W/m²; 4.1 V corresponds to
2/20/200/20000 W/m², i.e. the end value of the automatically set measuring range. A special cable is available for
connecting y-t recorders and other devices, which can be adapted to the respective device using standard adapters.
The digital output is designed as a bidirectional RS232 interface. Communication with a PC can be done with standard
software, e.g. "Hyperlink" take place, which is part of the Microsoft operating systems. After sending the ASCII
character "U", the KUV2.4WR MD replies with the character "U", followed by the numerical value of the current
irradiance, space, unit of measure and a semicolon as a conclusion.

In addition to a special cable for the computer connection, the RV2 transmission software is optionally available for
querying measured values and evaluating them. Details can be found in the associated documentation.
Calibration and maintenance
The radiometer is intended for checking the calibration of system sensors. It is possible to use several sensors
alternately on one device. Please order the device with the desired sensors straight away. The device must be
switched off when changing the sensors. After switching on again, the device automatically recognizes the connected
sensor and assigns its calibration value internally.
For calibration, the device including all sensors must be sent to us. When calibration is necessary depends on the
frequency of use and the irradiance levels to the sensor. We recommend recalibration after approx. 100 hours of
operation.
No repairs can be carried out by the user on the device and the associated sensors. In the event of errors, the device
and all associated sensors must be sent to us.
Calibration of the digital system sensor
The following sequence must be observed for calibrating digital or digital/analogue duty plant sensors:
1. Call Menu point cal. sensor (see menu)
2. Position the reference sensor in front of the UV lamp
3. Confirm the measured value with the red key (Enter)
4. Position the digital plant sensor in front of the UV spotlight
5. Confirm the measured value with the red key (Enter)
6. Darken the reference sensor (protect the sensor from UVC radiation, daylight allowed)
7. Confirm the measured value with the red key (Enter)
8. Darken the plant sensor (protect the sensor against UVC radiation, daylight allowed)
9. Confirm the measured value with the red key (Enter)
If the calibration is successful, calibr. OK! Will be shown in the display. If an error occurs during the calibration or the
calibration has been cancelled, the display shows calibr. invalid!
The calibration can be interrupted at any time with the yellow button (break).
Note: We assume no responsibility / liability for the customer calibration of system sensors.
Correction values greater than ± 25% compared to the factory calibration indicate damage to the sensor and require
repair / recalibration in the factory.

Menu structure Version 1.2
After switching on, press the red button again briefly to enter the main menu. The navigation is simple and usually
intuitive. The following overview shows the menu structure.
The colour of the arrows indicates which button must be pressed for navigation. With return and after selecting a
setting, the jump back to the basic display always takes place. After 2 minutes without pushing a button, the device
automatically returns to the basic display. When selecting medium-pressure lamps, an md in the first line before the
measured value is displayed in the measuring mode, e.g. R: md 0.000 W/m². To increase the operating time in the
battery operation, the backlight turns off after approx. one minute. Each button operation switches the backlight on
again. In the case of poor light conditions, the display light can be switched on and off manually using the green
button. The unit has a power cut-off which switches it off approximately 10 minutes after the last key operation. For
longer measurements, the continuous function must be activated via the menu. When the battery is discharged,
low bat alternates with the sensor information in the first display line.
