In order to calculate the global radiation in W/m
2
with respect to the output voltage signal of the
pyranometer, the pyranometer sensitivity must be set in the instrument, supplied with the pyra-
nometer itself. The sensitivity must be set in nV/(Wm
-2
) and range between 5000 and
30000 nV/(Wm
-2
). The default value is 10000 nV/(Wm
-2
). To set the sensitivity:
1. Press SELECT to display the MENU command in the command bar, then select MENU by
pressing the F2 key.
2. Select the CALIBRATION item using
S
and
T
, then press F3 ( OK command) to confirm.
Note : CALIBRATION item is not shown if the instrument is in protected mode. See para-
graph 8.2 to change the protection status.
3. The list of the connected probes is displayed. Each probe is identified by its own serial num-
ber and by the type of measurement. Select VP472 module using
S
and
T
, then press F3
( OK command) to confirm.
4. Set the first digit of the pyranometer sensitivity which measures the incident radiation us-
ing
S
and
T
, then select the command "-->" ( F2 key) to proceed to the next digit (the cur-
rently selected digit flashes). To return to the previous digit, select "<--" ( F1 key). After
setting all the digits, press OK ( F3 key) to confirm the value.
5. Set the first digit of the pyranometer sensitivity which measures the reflected radiation us-
ing
S
and
T
, then select the command "-->" ( F2 key) to proceed to the next digit (the cur-
rently selected digit flashes). To return to the previous digit, select "<--" ( F1 key). After
setting all the digits, press OK ( F3 key) to confirm the value.
Note : the second sensitivity is necessary only if an albedometer is connected; if this isn't
the case, leave the default value.
6. Press ESC twice to return to the measurement mode.

HOTOMETRIC AND RADIOMETRIC PROBES WITH
SICRAM
MODULE
The photometric and radiometric probes of LP471... series can be connected to the instru-
ment.
The measurement unit is chosen by the instrument depending on the probe connected. If sev-
eral measurement units are provided for the same probe, see paragraph 3.2 at page 13 for the
selection of the desired unit.
All the probes are factory-calibrated and do not require user calibrations.
