Spot Measurement
The spot measurement operates only in remote control (GPIB/USB) and not by using the keys.
This function returns measured data when recognizing specified commands regardless of the source mode
and Operate/Suspend/Standby.
The integration time for measurement can be set separately from the integration time for sweep.
NOTE:
ADC3 spot measurement returns to the previous measurement status after the specified function is mea-
sured.
(It returns to the Ir function in the sweep mode.)
Example of use (in the sweep mode)
As for I-V characteristic measurement of solar cells, temperature measurement is performed before and
after I-V measurement with the output status kept in Operate.
In ADC3 measurement, temperature measurement Tc1 is performed before and after sweep and reference
cell current measurement Ir is performed during sweep.
