3.1 Voltage Measurement

In the explanation below, we measure AC voltage fluctua-
tions for a one-week period using an AC transducer (0~10
VDC rms value output for 0~150 VAC) as an example. Moni-
tor voltage fluctuations for a one-week period by measuring
the output voltage every minute.

Settings:

Voltage is input to Channel 1.

Recording interval: 1 min., Time axis: 1 hour, Recording period: 7 days

Data will be saved onto a PC card in real time.

Transducer

Memory HiLogger

AC Adapter

Input Cables

Instrument and Accessories Required for Measurement

• Memory HiLogger

• AC adapter

• PC card

• Input cables

• Flat blade screwdriver
