22. The instrument displays a screen similar to the one
reported here to the side, where:
 Vdc = DC output voltage from module/string
 Irr = irradiance measured by supplied reference cell
 Tc = temperature of module. The herewith options are
available for this field:
 AUTO  automatic mode of temperature measurement
 Number  MAN or AUX mode of temp. measurement
 “ - - - “  AUX mode with no connected probe
 Module = type of selected module
 Temp = measurement mode of module temperature
 The symbol “
” fixed at display means that a stable
RF connection is established with the remote unit

23. Press ENTER key, select the “Activate Rec.” item and
confirm with ENTER. The message “Remote unit in
recording…” is displayed on the meter. In this condition is

CAUTION
At the press of GO/STOP key some different error messages can be

“Measuring…” is shown on the display for some seconds,
depending on the level of power during test.
