Introduction Features of Hioki Power Analyzer
Thank you for purchasing the Hioki VT1005 AC/DC High
Voltage Divider.
This Setup Guide describes the settings of the Hioki Power
Analyzer (PW8001, PW6001, PW3390) when they are used
with the VT1005.
Refer to the Instruction Manual of the Power Analyzer for
more information about how to use the Power Analyzer.

1. Setting the Scaling (VT Ratio/Rate)
Enter 1000 in the VT ratio/rate.
You can directly read values input from the VT1005 by setting the VT1005’s dividing ratio/rate to the Power Analyzer.
PW8001
Press the INPUT key. → Touch [CHANNEL].
→ Touch the channel detail display area.
PW6001
Press the INPUT key. → Touch [CHANNEL].
→ Touch the channel detail display area.
PW3390
Press the SYSTEM key. → Select [Input].
2. Setting the Phase Correction/Compensation Value
Phase correction/compensation for the Voltage Divider can be performed by setting a phase correction/compensation value
to the Power Analyzer to reduce power measurement errors in the high-frequency domain. The settings vary depend on the
Power Analyzer being used.
IMPORTANT
Enter a phase correction/compensation value correctly. Incorrect
settings may allow correction/compensation to increase measurement
errors.

Enable the voltage phase correction/compensation, and then
enter a correction/compensation value chosen from Table 1,
The phase correction/compensation value varies depending on the length of the L9217 Connection
Cord used with the VT1005.
Press the INPUT key. → Touch [CHANNEL].
→ Touch the channel detail display area.

2-2. When the PW6001 or PW3390 is used
Enable the current sensor phase correction/compensation, and then enter a
correction/compensation value chosen from Table 2.
The phase correction/compensation for the VT1005 and the current sensor can be performed by using the phase correction/
compensation function of the current sensor.
The phase correction/compensation value varies depending on the current censer to be used and the length of the L9217
Connection Cord used with the VT1005.
