Operating Manual
1 Device Description
1.1 Application
The diagnostic dosemeter CONNY II is suitable
for measurements free in air or at the radiation
entrance side of the test object.
The CONNY II can be used with medical
X-ray equipment for radiography, fluoroscopy,
and mammography (anode-filter combinations:
W/2.5 mm Al at 70 kV and 100 kV as well as with
Mo/30 µm Mo at 30 kV).
The CONNY II can be used for image quality
assurance in diagnostic X-ray departments for
constancy tests according to DIN 6868-3, -4, -7,
and -13. For this purpose, a test object comply-
ing with the requirements of the standards shall
be placed in the path of the X-rays, and the dose
occurring at the radiation entrance side of the test
object during radiography shall be measured. At
X-ray systems used for fluoroscopy, the dose rate
at the radiation entrance side of the test object
shall be determined by measuring the dose for a
defined period of time.
When operated within the rated range of use, the
CONNY II fulfills the requirements for diagnostic
dosemeters set forth in IEC 61674.
The CONNY II consists of a battery operated
electrometer and an undetachable semiconductor
detector.
It can be used in combination with test objects of
the NORMI series.

2 Putting into Operation
The CONNY II is battery operated and features a
voltage monitoring function. If the battery voltage
decreases below a lower limiting value the device
switches off automatically. The battery lifetime for
continuous operation is approximately 18 hours.
A battery symbol appears behind the measuring
value approximately 3 hours before the auto shut-
off.
HINT
When rechargeable batteries are used the
LOW BAT message is displayed earlier.
Switching on
•Turn the CONNY II on with the ON/OFF switch.
➔During the display of the firmware version,
all measuring ranges are zeroed automati-
cally.
➔After zeroing, the CONNY II is ready for
operation.
➔Default values:
Radiation quality: 70/100 kV
Measuring range: HIGH
Measuring mode: DOSE
Start a measurement by irradiating the detector
(refer to 3 "Measuring ").
The CONNY II features an auto shutoff function
which switches off the device after 5 min without
irradiation or key operation.

3 Measuring
3.1 General Information
Default settings
After power-up, the following default values are
preset in the CONNY II:
– Radiation quality: 70/100 kV
– Measuring range: HIGH
– Measuring mode: DOSE
Before starting a measurement, the defaults can
be adapted to the measuring conditions with the
kV, RANGE, and MODE keys.
– Fluoroscopy:
measuring range LOW (5 µGy/s ... 3 mGy/s)
– Radiograpy:
measuring range HIGH (0.5 ... 300) mGy/s
Measuring quantities
The CONNY II can be used to measure the fol-
lowing measuring quantities:
– air kerma rate (dose rate mode)
– air kerma (dose mode)
– time (irradiation or exposure time)
Measuring ranges, refer to 5 "Technical Specifi-
cations"
Detector
The detector of the CONNY II can be attached to
the test object by means of the supplied reclos-
able fastener. The detector surface must be irra-
diated perpendicularly (Figure 4), and the entire
detector must be located in the radiation beam.
Figure 4: Preferred direction of radiation
When fastening the detector to the test object,
take care not to cover measuring areas or test
structures with the detector cable.

3.2 Performing a
Measurement
•Place the CONNY II on the patient couch
outside the radiation beam and fold out the
bracket at the back of the device if necessary.
•Before the measurement, attach the detector
of the CONNY II to the test object. The detec-
tor must be irradiated perpendicularly, and it
must be completely located in the radiation
beam; the reference point is at the center of
the entrance window.
•Use the ON/OFF switch to turn the CONNY II
on; at the same time, all measuring ranges will
be zeroed automatically.
•Adapt the preset parameters to the measur-
ing conditions with the kV, RANGE, and MODE
keys.
– Measuring range for fluoroscopy:
LOW (dose rates in the range from
5 µGy/s to 3 mGy/s)
– Measuring range for radiography:
HIGH (dose rates in the range from
0.5 to 300 mGy/s)
•Start a measurement by exposing the detector
to radiation. The CONNY II features an auto-
start function, which means that a measure-
ment will start automatically when the detector
detects radiation. The zero adjustment of the
last switch-on will be taken into account.

Measurement readout
While a measurement is in progress, the keyboard
of the device is locked and the parameter set with
the MODE key is displayed. For the duration of the
measurement, the letter M is visible in the upper
left of the display.
HINT
About dose rate measurements:
If the selected measuring quantity is dose rate,
the mean dose rate will be displayed first after
the radiation is switched off. The first and the
last 3 seconds of the measuring interval are not
included in the calculation.
The minimum measuring time is 8 seconds
(effective measuring time of 2 s + waiting period
of 2 x 3 s that is not taken into account).
The value is averaged over a maximum of
20 seconds (tend –23 s to tend – 3 s). Before
the minimum measuring time is reached, the
flashing label "Time" will be displayed in addi-
tion to the dose rate. If a measurement is termi-
nated during this period, the readout is reset to
0.00 mGy/s. If the measurement takes longer,
the message "Time" will be displayed perma-
nently. After the end of the measurement, the
mean dose rate will be displayed with the label
"mean".
The measured value should always be displayed
with a minimum resolution of 1 % (100 digit). If
this resolution is not available in the HIGH mea-
suring range, switch to the LOW measuring range.
If measurements in the LOW measuring range
exceed the maximum dose rate, a condition indi-
cated by the message OL, switch to the HIGH
measuring range.
Interrupting a measurement
If a measurement is interrupted for less than
3 seconds, it will continue after the interruption. If
the interruption lasts longer than 3 seconds, the
measurement will be canceled and the current
measured value will be displayed. If a measuring
signal becomes available again afterwards, the
readout will be reset to zero and a new measure-
ment will be started (auto-reset). The values of the
previous measurement are no longer available in
this case!
Terminating a measurement and reading the
measured values
After the measurement, the measured parame-
ters dose, dose rate, and time can be displayed by
pressing the MODE key. The last parameter set
with the MODE key will be displayed during the
next measurement if the device remains switched
on.
The CONNY II features an auto-shutoff function,
which means that the device switches off if no
radiation is detected and no key is pressed for a
period of 5 minutes.
HINT
All measured values will be lost when the
CONNY II is switched off. Therefore, be sure to
read off the measured values within 5 minutes
after the measurement!
