2. DESCRIPTION OF THE FUNCTIONS
The Photo-Radiometer Model HD2302.0 keyboard is composed of single-function keys, except the
ON-OFF/Auto-OFF key that has two functions (see the description of the key below).
The pressing of a key is accompanied by a short confirmation "beep": a longer "beep" sounds if the
wrong key is pressed.
Each key specific function is described in detail below.
This key has two functions:
ON/OFF: to turn the instrument on press ON, to turn it off press OFF.
The turning on enables all display segments for a few seconds, starts an Auto-test including the detection of the probe connected to the input, and sets the instrument ready for normal measurement.
The following is displayed:

AUTO/OFF: the AutoPowerOff function can be disabled by simultaneously pressing this key
and the "HOLD" key when turning the instrument on.
During turning on, should no probes be connected, the "PROB" message is displayed in the line
for symbols for a few seconds, while the "ERR" message is shown in the central part of the display.
When the probe is inserted into a functioning instrument, it is not detected: as the data are
captured upon turning the instrument on, it is necessary to turn it off and on again.
Caution! Replace the probes when the instrument is off.
The instrument has an AutoPowerOff function that automatically turns the instrument off after about
8 minutes if no key is pressed during the intervening time.
Press simultaneously the ON/OFF key and the HOLD key to disable this function.
In this case, remember to turn the instrument off using the ON/OFF key: disabling of the automatic
turning off is shown by the blinking battery symbol.
It resets the maximum, average, and minimum value of the captured measurements.

By pressing this key once the maximum (MAX) value of the measurements captured by the probe
connected to the instrument is displayed, updating it with the acquisition of new samples;
- by pressing this key again the minimum (MIN) value is displayed;
- by pressing this key a third time the average (AVG) value is displayed.
The acquisition frequency is once a second.
The MAX, MIN and AVG values remain in the memory until the instrument is on, even after exiting the DATA calculation function. When the instrument is off, the previously memorized data are
cleared. Upon turning on, the instrument automatically starts memorizing the MAX, MIN and AVG
values.
To reset the previous values and start with a new measurement session, press until the
FUNC_CLRD message appears.
By pressing this key the current measurement update is frozen and the "HOLD" message will appear in the upper left-hand corner of the display. To return to the current measurement, press the
key again.
It is also used to disable the AutoPowerOff function (see the description of the key on page 7).
By pressing this key the unit of measurement of the main input quantity is selected: the unit of
measurement will appear in the upper part of the display; the measured value will be displayed in
the central line. By repeatedly pressing the UNIT key, the desired unit of measurement can be selected. In the combined probes, UNIT key allows to select one of the available measures (in these
probes, unit of measurement cannot be changed).
NOTE: The units of measurement available are determined according to the probe connected to
the input, as reported in the following table:

probes that measure:
illuminance (LP471 PHOT),
irradiance (LP471 RAD, LP471 UVA, LP471 UVB and LP471 UVC),
PAR (LP471 PAR),
luminance (LP471 LUM 2),
effective irradiance according to the UV action curve (LP471 ERY),
effective irradiance in the spectral range of blue light (LP 471 BLUE),
illuminance, UVA irradiance and UVA irradiance - illuminance ratio (Combined probe LP
471 P-A - please see note 1),
total effective irradiance UVA + UV-CB according to the UV weighting curve (combined
probe LP 471 A-UVeff for measuring total effective irradiance in the range 250...400 nm please see note 1),
global solar irradiance in the spectral range 400…1100 nm with silicon photodiode (LP 471
SILICON PYRA),
global solar irradiance in the spectral range 300…3000 nm. Probe consisting of a second class
pyranometer LP PYRA 03 and a 5 m long cable with SICRAM module (LP 471 PYRA 03),
global solar irradiance in the spectral range 300…3000 nm. Probe consisting of a first class
pyranometer LP PYRA 02 and a 5 m long cable with SICRAM module (LP 471 PYRA 02).
Note 1: probes LP 471 P-A and LP 471 A-UVeff work with instruments HD2302.0 having firmware
version “HD2302.01” and following. On the back of these instruments a label shows version and
date of the firmware. To update previous instruments, contact your dealer Delta Ohm.
All probes, except LUM 2, are provided with a diffuser for cosine correction.
Upon turning on the instrument automatically detects the probe connected to the input: it is sufficient to connect it before turning the instrument on.
The unit of measurement is determined according to the probe connected to the input: use the
UNIT key to change the unit of measurement.
In the combined probes, UNIT key allows to select one of the available measures (in these probes,
unit of measurement cannot be changed).
All probes are calibrated in the factory; no calibration is required by the user.
The probe is detected during turn on: if a probe is connected and the instrument is on, it is
necessary to turn it off and on.

3.1 COMBINED PROBE LP 471 P-A
LP 471 P-A is a two sensors combined probe with SICRAM module for measuring illuminance
(lux) with standard photopic spectral response and irradiance (μW/cm2) in UVA spectral range
(315...400 nm, with peak at 365 nm). Moreover probe provides the ratio of UVA irradiance and illuminance in µW/lumen (quantity of interest in the museums field).
Both sensors are equipped with diffuser for the correction according to the cosine law.
At switching on, the instrument displays alternatively the measures of the two sensors. Pressing any
key (excluded ON/OFF key), automatic commutation is turned off. To reactivate it, press HOLD
and REL keys together.
To select the measure to display, press UNIT key.
3.2 COMBINED PROBE LP 471 A-UVEFF
LP 471 A-UVeff is a two sensors combined probe with SICRAM module for measuring total ef-
fective irradiance according to the UV weighting curve. Two sensors are used to correctly measure
the total effective irradiance in the range 250...400 nm.
Both sensors are equipped with diffuser for the correction according to the cosine law. The probe
provides the total effective irradiance (“Er” at display), the effective irradiance in the range UV-CB
(“BC” at display) and the UVA irradiance (“A” at display).
At switching on, the instrument displays alternatively the measures of the two sensors. Pressing any
key (excluded ON/OFF key), automatic commutation is turned off. To reactivate it, press HOLD
and REL keys together.
To select the measure to display, press UNIT key.
3.3 PROBES LP 471 PYRA 02 AND LP 471 PYRA 03
LP 471 PYRA 02 and LP 471 PYRA 03 probes measure the global solar radiation in the spectral
range 300…3000 nm. They are composed of a first class (LP PYRA 02) or a second class (LP
PYRA 03) pyranometer and a cable with SICRAM module.
Since calibration data of pyranometer are saved in SICRAM module, the cable cannot be used together with other pyranometers.
The global solar radiation is expressed in W/m2 or in μW/cm2. Measuring range is 0…2000 W/m2.
The module is equipped with a 5 m or 10 m long cable ending with a 4 poles male connector to be
inserted in the female connector of the pyranometer.
No user calibration is required.
The SICRAM module is recognized at the instrument switching on, then it’s absolutely necessary to
connect the module before turning the instrument on.
3.4 PROBE LP 471 SILICON-PYRA
LP 471 Silicon-PYRA measures the global solar radiation using a silicon photodiode in the spec-
tral range 400…1100 nm.
The diffuser allows a correction according to the cosine law.
The probe is suitable for the measurement of natural sunlight. Under overcast skies, or for reflected
light measurements the use of a thermopile pyranometer is recommended (LP 471 PYRA 03 or LP
471 PYRA 02).

Typical response curve
The LP 471 ERY probe measures the total effective irradiance (W
eff
/m2) weighted according to the
UV action curve (CEI EN 60335-2-27). The particular photodiode and a proper combination of filters, brings the probe's spectral curve close to the UV action curve.
The CEI EN 60335-2-27 norm prescribes that, during the first tanning treatment, the dosage of 100
J/m2 cannot be exceeded, and that the maximum yearly dosage must not exceed 15000 J/m2.
The typical spectral curve of the LP 471 ERY probe is illustrated in the figure together with the UV
action curve: the agreement between the two curves mean reliable measurements are obtained using
the different types of lamps (and filters) used by the tanning machines currently on the market.
All probes are individually calibrated in the DeltaOhm photo-radiometry laboratory, using a dualbeam monochromator. The calibration is performed at 295nm, using a calibrated photodiode as
reference.

Typical response curve
The radiometric probe LP 471 BLUE measures the irradiance (W/m2) in the spectral range of
Blue light. The probe consists of a photodiode with an appropriate filter and is provided with a
diffuser for correct measurement according to the cosine law.
The spectral response curve of the probe allows to measure the effective irradiance for blue light
hazard (curve B (λ) according to the standards ACGIH / ICNIRP) in the spectral range 380nm ...
550nm. Optical radiations in this range can produce photochemical retinal injury. Another field
of application is the monitoring of the blue light irradiance in the treatment of neonatal jaundice.
