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.

1. Make sure the instrument is OFF.
2. Connect the AC adapter to the instrument.
3. Plug the AC adapter into the power outlet.
See Section 2.1 "Connecting Power" (page 21) of Instruction Manual.
4. Insert the PC card.
See Section 7 "Saving Measurement Data" (page 113) of Instruction Manual.
5. Remove the terminal board cover.
• To avoid the danger of electric shock, never connect the
power line to which the measurement cable is connected to
this unit while the power line is live.
• Never apply more than 30 Vrms AC or 60 VDC between ana-
log inputs, or between analog inputs and chassis ground.

6. Using the supplied flat blade screwdriver, connect the measure-
ment cables to channel 1 on the terminal board.
Be sure that the polarity of the cable connection is correct.
See Section 2.2 "Connecting Measurement Cables" (page 25) of Instruction Manual.
Recommended Lead Wire
When connecting the input cable to a transducer, refer to the
instruction manual of the transducer and be sure to connect the
cable correctly.
7. Replace the terminal board cover to protect the terminal board, and
for safety.
8. Turns on the power switch.
