keys, except the ON-OFF/Auto-OFF key that has two functions (see the description of

the key below).

he 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.

his key has two functions:

•ON/OFF: to turn the instrument on press ON, to turn it off press OFF.

he 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. he 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 "PRO " 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.

he 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

and by pressing this key a third time the average (AVG) value is displayed.

The acquisition frequency is once a second.

he MAX, MIN and AVG values remain in the memory until the instrument is on, even

after exiting the DA A 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.

o reset the previous values and start with a new measurement session, press the

CLR key 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. o return to the

current measurement, press the key again.

It is also used to disable the AutoPowerOff function (see the description of the ON/OFF

key).

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 UNI

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: he units of measurement available are determined according to the probe

connected to the input, as reported in the following table:

PRO ES AND MEASUREMENTS

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

radiometric probes that measure:

•illuminance (LP471PHO ),

•irradianace (LP471RAD, LP471UVA, LP471UVB, LP471UVC and LP471UVBC),

•PAR (LP471PAR and LP471PAR02),

•luminance (LP471LUM2),

•effective irradiance in the spectral range of blue light (LP471BLUE),

•illuminance, UVA irradiance and UVA irradiance-illuminance ratio

(Combined probe LP471P-A),

•total effective irradiance UVA + UV-C according to the UV weighting

curve (combined probe LP471A-UVeff for measuring total effective irradiance

in the range 250...400 nm),

•global solar irradiance in the spectral range 400…1100 nm with silicon

photodiode (LP471SILICON-PYRA),

•global solar irradiance in the spectral range 300…2800 nm. Probe consisting

of a Spectrally Flat Class C pyranometer LPPYRA03 and a cable with SICRAM

module (LP471PYRA03),

•global solar irradiance in the spectral range 283…2800 nm. Probe consisting

of a Spectrally Flat Class B LPPYRA02 or Spectrally Flat Class A pyranometer

LPPYRA10 and a cable with SICRAM module (LP471PYRA02 – LP471PYRA10).

All probes, except LUM2, 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.

he unit of measurement is determined according to the probe connected to the

input: use the UNI key to change the unit of measurement.
