(5) FFT data
Function
Saves the noise measurement FFT spectrum that is currently displayed on the Waveform/Noise
screen
Save destinations USB memory/CF card
Able to specify the folder to save.
Data format CSV file format (with read-only attribute)
With functionality for switching the delimiter based on the selected file format
CSV: Comma (“,”) as measurement data delimiter and period (“.”) as decimal point
SSV: Semicolon (“;”) as measurement data delimiter and comma (“,”) as decimal point
File name
Automatically generated; extension: CSV
Constraints Cannot be saved while auto-save operation is in progress.
9. Synchronous Control Function
Function Synchronous measurements are available by using sync cables to connect one Model PW3390 as
a master and one or more as slaves.
Clocks and data updates are synchronized when the slave instrument is turned on.
Afterwards, resynchronization is performed at each second of the clock (disabled when the slave is
started while the master is off).
When internal settings match, auto-save is available while synchronized.
Synchronized items Clock, data update interval (except for FFT calculations), integration START/STOP, DATA RESET,
certain events
Event items Hold, manual save, screen capture
Synchronization timing Clock, data update interval: within 10 s after power-on by a slave PW3390
START/STOP, DATA RESET, event: Upon key-press and communications operations on the
master PW3390
Synchronization delay Maximum 5 s per connection. Maximum synchronization delay of an event is +50 ms
10. Bluetooth
logger connectivity
Function Sends measured values wirelessly to logger by using a Bluetooth
serial conversion adapter.
Supported devices Hioki LR8410 Link-compatible loggers (LR8410, LR8416)
Sent data Measured values assigned to the D/A CH9 to CH16 analog output parameters
11. Other functions
Real-time clock function Auto-calendar, leap-year correcting 24-hour clock
RTC accuracy ±3 s per day (25°C)
Sensor recognition Current sensors are automatically recognized when connected
Sensor range and connection state are detected, and warning indicators displayed as needed
Excluding the CT7000 series sensors
Warning indicators When peak over occurs on voltage and current measurement channels
When no sync source is detected Warning indicators for all channels are displayed on all pages of
the MEAS screen.
Key-lock Toggles on/off by holding the ESC key for three seconds.
A key-lock indicator is displayed when the keys are locked.
System reset Returns all settings to factory defaults
However, language and communications settings are unaffected.
Power-on reset Holding the SHIFT key when turning the power on returns all settings including language and com-
munications settings, to factory defaults.
File operations Media content list display, format media, create folders, delete files and folders, copy between stor-
age media
