5.1.5. Irradiance
1. Move the cursor to “
Irradiance
” by means of the arrow
keys (
,
) and confirm with
ENTER.
2. The display shows the screen with the options: “
Irr min
IV
”
which allows to set the minimum threshold of
measured irradiance expressed in W/m
2
, used by meter as
reference during the I-V curve measurements and “
Irr min
EFF
” (SOLAR I-Vw or SOLAR I-Ve which allows to set the
minimum threshold of measured irradiance expressed in
W/m
2
, used by meter as reference during the check PV
efficiency measurements
3. Set the value by means of the arrow keys (
,
). The
accuracy indicated in this manual is granted under
condition indicated in § 10.1 and § 10.2. In I-V curve
measurement the value is set within the
0
800 W/m
2
interval while

for the PV check
operations (SOLAR I-Vw or SOLAR I-Ve)
4. Confirm with
SAVE
and the “Saved data” message is
displayed for a while. Press
ESC/MENU
key to exit without

CAUTION
The “0 W/m2” setting for parameter “Min Irr IV” allows carrying out I-V
measurements without the following conditions being checked:
Connection of reference cell to input IRR of the instrument
Unsteady irradiation values
Number of modules consistent with the measured open circuit voltage
5.1.6. DC Clamp (SOLAR I-Vw or SOLAR I-Ve)
This option allows setting a
possible
correction factor K for the DC clamp, in order to improve
current measurement. If present, the correction factor is indicated on the rear label of the clamp
itself, indicated as:
K= X.xxx
In case no label is present, set k = 1.000
1. Move the cursor to “
DC Clamp
” by means of the arrow
keys (
,
) and confirm with
ENTER
2. The item: “
DC clamp k
” is shown at display to set the
corrective factor in a interval within
0.950
and
1.050
. Set
the value by means of the arrow keys (

3. Confirm with
SAVE
and the “Saved data” message is
