9. 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

temperature among the modes listed:
 Auto”  automatic measurement performed by the
meter depending on the measured value of open
voltage of modules (recommended method)
 “Manual”  setting of a module temperature value by
the operator on the corresponding “Value” field
 “Aux”  setting of temperature of module performed by
auxiliary probe
