1. GENERAL CHARACTERISTICS

The Photo-Radiometer Model HD2302.0 is a portable instrument, fitted with a large LCD display

for visualization of the measured data. It measures:

illuminance;

luminance;

PAR;

irradiance (across VIS-NIR, UVA, UVB and UVC spectral regions or in the measured effec-

tive irradiance according to the UV action curve).

The probes are fitted with the SICRAM automatic detection module, with the factory calibration

settings already being memorized inside. In addition to detection, the unit of measurement selection

is also automatic.

The Photo-Radiometer measures the following instantaneous quantities:

2.DESCRIPTIONOF 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 de-

tection of the probe connected to the input, and sets the instrument ready for normal measurement.

The following is displayed:

MIN

min s

mµ

>>>

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 dis-

play.

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 exit-

ing 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 ap-

pear 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 se-

lected. 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:

Type of measurement

Unit of Measurement

Illuminance (PHOT)

lux - fcd

Irradiance (RAD - UVA - UVB - UVC - PYRA)

W/m2- W/cm2

PAR

Luminance (LUM 2)

cd/m2

It displays the difference between the current value and that measured on pressing the key. The

"REL" message is displayed on the left.

To return to the normal measurement, press the key again.

3. PROBES AND MEASUREMENTS

The instrument works with probes of the LP471… series: these are photometric and radiometric

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 suffi-

cient 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 il-

luminance 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 LP471 PYRA 02 AND LP471 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 to-

gether with other pyranometers.

The global solar radiation is expressed in W/m2or 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 LP471 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).
