■ Maximum recording times with Memory function (auto saving)
• At sampling speeds of 100 ms/division (1 ms sampling) and lower, real-time saving on media becomes possible.
• Setting recording length to an arbitrary value allows increasing the 200,000 division limit up to a maximum of
320,000 divisions in 1 division units.

■ Chart recording reliably captures noise events (Recorder function)
● High-speed sampling ensures that noise events are captured also with slow recording
● Data compression achieved by recording maximum/minimum value pairs
● Up to 416 days of recording time with maximum memory capacity (1 hour/division)
● Chart output enables permanent recording
* When opening data created with the Recorder function on a computer, the maximum and minimum
data pairs are lined up in a time series.
* Length of printer paper roll is 30 meters. Paper can be changed during operation without stopping
the recording process.

■ Maximum recording times with Recorder function
• With settings between 100 and 200 ms per division on the time axis, continuous recording is not
possible if printer is ON.
Highlights Memory function
Recorder function
■ Simultaneous recording on recording media (Memory function)
● Automatic data saving on CF card or HDD
● During high-speed sampling, data are written to internal
RAM first and later saved on other media
● During low-speed sampling, data are written to internal RAM
and sequentially saved on other media
● Highly suitable for long-term recording
* Available recording duration is determined by internal RAM capacity, not by
external media.
