Installation and maintenance
UV-Radiometer of the ТКА-UV model is a grating-based polychromator with registration of decom-
posed radiation by a microprocessor-controlled linear photodiode array, sending digital data to a lap-
top computer compatible with OS Windows® PC — ASUS® Eee PC 701, where the signal is digi-
tally processed with subsequent displaying of data on the irradiation levels.
Eee PC 701 is a 7-inch laptop which is a classic notebook, with a lockless cover. The laptop has no
hard disk, its function is performed by a 4 Gb flash memory. The laptop is supplied with a compact
power unit resembling more a charger for a mobile phone than the one for a laptop.

Program operation.
Important! For the calibration, it is necessary to braid into the device a program of manual switching
of ranges (with the help of WSD-application file grad.hex).
Configuration of WSD-application:
Field of selecting a
calibration step

http://www.foxitsoftware.com For evaluation only.

The device should be calibrated in the specified order. The program does not control the operator’s
actions on the selection of the step, therefore when the order is infringed, failures in operation are
possible.
The selection of the calibration step is effected through pressing the respective button.
Dark current measurement
Generated by Foxit PDF Creator © Foxit Software
http://www.foxitsoftware.com For evaluation only.

When fulfilling the requirements of the program, it is necessary to close the lens of the device and
install with the range selection button (the button on the photometer head increases the value succes-
sively) with the recommended program (a black digit).
On the panel on the right the current measurement range is displayed (a green digit) and the highest
value. If the current range does not match the required one, then the digit of the current range will be
displayed in the red color and the button of starting the measurement in the current window of the
program will be unavailable. Specifying the required range with the button on the photometer head,
start the measurement by pressing the button Measure in current range in the current window of the
program.
When the measurement is completed, the program will offer to make a measurement on the next
range.
There are 9 ranges altogether, the integral action time is from 4 seconds (range 0) to 16 msec (range
8).
When the measurement is completed in all ranges the program will preserve the matrix of dark cur-
rents and return to the selection of a calibration step.
Determining spectral sensitivity of the device
Place the photometer head in parallel to the plane of the item which is being measured. See to it that
the shadow of the operator who conducts the measurement does not cast itself onto the photohead
window, as well as the shadow of any irrelevant objects that are temporarily present.

To operate on this step, install the photohead on the photometer bench and switch up the reference
source DNK-90.
The basic operation is the same as in step 1.
Measurement in each range should be conducted with the steady-state value of the maximum close to
4,000 units.
Do not allow overfilling (4095)!
If it is impossible to reach the normal level of the spectral sensitivity on the last ranges, the button
Low Level should be pressed in the current window of the program; the remaining ranges will be
filled with the values of the last one which was successfully measured.
Determining the range lacing ratios
The ratios are calculated following the same scheme as in steps 1 and 2.
Place the photometer head in parallel to the plane of the item which is being measured. See to it that
the shadow of the operator who conducts the measurement does not cast itself onto the photohead
window, as well as the shadow of any irrelevant objects that are temporarily present.
To begin the measurements, place the photohead on the bench so that the maximum signal
3,800 … 4,000 units might be obtained. After the measurement in the selected range, not changing
the position of the photohead, increase with the button on the head the range to the next one and re-
peat the measurement.

The quotient of the measured signals for each will be preserved. Then it is necessary to reach again
the maximum level of the signal 3,800 … 4,000 units, shifting the photohead on the bench, and to
make two measurements on adjoining ranges. In case it is impossible to increase the signal to the ac-
ceptable value, press the button Low Level, and the remaining ratios will be calculated on the basis of
the available measurements which were successfully made.

Calculating the total irradiance ratio
Place the photometer head in parallel to the plane of the item which is being measured. See to it that
the shadow of the operator who conducts the measurement does not cast itself onto the photohead
window, as well as the shadow of any irrelevant objects that are temporarily present.
In this mode the device is installed on the bench so that on the zero range the maximum signal might
be obtained in the area of 3,900 … 4,000 units. The position on the bench is fixed, the photohead re-
moved. Then, in the fixed point reference receivers determine irradiance in the wavelength range 220
… 400 nm (zones А, В, С). After that, the photohead returns to the reference point, and the irradiance
value is entered into the entry field, and the total irradiance ratio calculated.

Additional energy adjustment by zones
Place the photometer head in parallel to the plane of the item which is being measured. See to it that
the shadow of the operator who conducts the measurement does not cast itself onto the photohead
window, as well as the shadow of any irrelevant objects that are temporarily present.
By the method stated at the previous step, irradiance is determined separately by zones А1, А2, В and
С.
Measurement can be made in any range. It is recommended for calibration to select the level of ir-
radiance at which the maximum value is at the level of 3,000 … 3,900 units.
Into the field of the respective UV zone the measured value is entered and calculation made. Above
the entry field it is necessary to place a flag for confirming the entry of changes. When the flag is
removed, the changes for a given field will not be rewritten.
The values of the obtained ratios are used thereafter as supplements to the ratio of total energy ad-
justment. The button Value Reset serves for zeroing the calculated ratios. In this case irradiance is
calculated only with taking the total ratio into account.
Output data
After the fulfillment of the necessary operations the calibration program retains all the calibration
data in the Windows register into the branch
«HKEY_CURRENT_USER\Software\TKA\VDUV\1.0».

Program setup
The user zone range specifies the irradiance measurement range within the user-assigned boundaries.
Options of Graph group control the spectrum display.
Display group allows the format of the main window to be set up. The switch Show text only
switches the main window of the program to the mode of either display of irradiance only (turned
on), or the mode of simultaneous display of irradiance and signal spectrum (turned off).
In the mode of simultaneous display the irradiance output can be controlled for each zone.
Important! For the operation mode it is necessary to braid into the device a program of manual
switching of ranges (with the help of WSD-application file work.hex).
Configuration of WSD-application:

Program operation
Place the photometer head in parallel to the plane of the item which is being measured. See to it that
the shadow of the operator who conducts the measurement does not cast itself onto the photohead
window, as well as the shadow of any irrelevant objects that are temporarily present.
Upon being started, the program scans the USB bus and in case the device is detected displays Ready
in the status line and starts automatically to display the data received from the photohead. When there
is no connection, the program displays Searching… in the status line.
The four buttons of the control panel are designed for storing data being received into a text file, the
spectrum graph into a file, setting up the program, and outputting additional information correspond-
ingly. The spectrum graph is stored in BMP format.
For the user’s convenience data are stored into a text file also through pressing the button ENTER.
