Other Characteristics
9.5.2 Function Specifications
Execute the functions from the PC application via communications.
Monitoring function
Measured value recording function
Temperature Within ±0.05 f.s./°C
Effect of common-
mode voltage Within±0.5%f.s.
(Common-mode voltage 300 V, 50Hz/60Hz)
Actual time accuracy ±100 ppm
(Reference value at temperature from 0 to 50°C (32 to 122°F) without using communi-
cations module)
Effect of
electromagnetic field Within ±2% f.s.
(in field of 400 Vrms/m and 50/60Hz)
Zero suppression Voltage : Less than 0.5% f.s.
Current : Less than 0.5% f.s.
(less than 0.9% f.s. when using the 9695-02 with 5A range selected)
Power : When voltage or current is 0
This function outputs the current measured values (instantaneous values).
Measurements are recorded at a set recording interval.
Real-time manage-
ment This is automatically set from the PC application at the start of recording.
Recording start Immediate start/Reserved-time start
Recording end Manual end/Reserved-time end
Operation when
memory is full Memory full stop /Endless

Set the condition before the start of recording.
Recording interval 1/2/5/10/15/20/30 sec., 1/2/5/10/15/20/30/60 min.
Recording mode Instantaneous value
MAX/MIN/AVE
Instantaneous value + MAX/MIN/AVE
Total 3 modes
Set the mode before the start of recording.
The types of values for recorded measurement items vary depending on the recording
mode.
Instantaneous value mode: instantaneous value
MAX/MIN/AVE recording mode: maximum value, minimum value, and average value
Instantaneous value + MAX/MIN/AVE recording mode: instantaneous value, maximum
value, minimum value, and average value
Recorded data
