6.3.5. Reset Media
If irradiance values are measured the instrument provides an outcome comparing the
measured values with the average values calculated according to previously saved
measurements.
Therefore in this case the average values calculated by the instrument play an important
role.
In case you start a new set of measurements with significant variations in irradiance and
temperature it is advisable to set the reference average values to zero in order to
recalculate based on new measurements.
To reset the average values keep to the following steps:
1. Under mode IVCK, press ENTER key, select “Reset
Media” and confirm by pressing ENTER to zero the
average values calculated till then.

The average values are automatically reset even modifying and saving one of the
following parameters:
 FV module type
 Number of modules per string
The average values are not reset if the operator changes working mode (for example he
goes to the overall detection of the I-V curve to effect string analysis in deep) and go back
to this mode.
