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
