3.1 Checking the Measurement Target
48
To carry out proper resistance measurement, change the measurement conditions appro-
priately according to the measurement target. Before starting measurement, use the exam-
ples recommended in the following table to configure the instrument.
*1: When there is sufficient margin with regard to the rated power, select High.
*2: When the measurement target significantly depends on temperature, use the tempera-
ture correction function.
*3: When there is sufficient margin with regard to the allowable applied voltage, select ON.
When measuring a commercial power supply transformer using an external trigger, mea-
surement cannot be performed using the delay setting preset. Either make the delay ade-
quately long or measure using the internal trigger (p.84).
