Window Recording
Endless recording is possible by specifying the ring buffer area (maximum 2G points/ch) as the window recording time. If you do not know when an abnormality will occur, you may miss the abnormal data if you set the recording time and measure. By ringing the recording area, you can always save the latest data.
The latest data is always recorded.
Selectable for SSD Recording
Omniace is a digital recorder that performs analog to digital conversion on all inputs and records those signals. Due to the relationship between the speed of analog to digital conversion and the frequency component of the input signal, the data may or may not be measured correctly.
Normal Data
Normal data is recorded at each designated recording speed. (■ points)
If the signal changes too fast relative to the recording speed, the data singular point (peak value) may not be recorded. Memory recording can measure this type of data.
Peak Data
Peak data is sampling (■, ■, and □ points) between the designated recording speed at the fastest AD-conversion rate, and records two data points, the maximum value (■ points) and the minimum value (■ points). The amount of data can be compressed without losing the data singular point (peak value).
Printer recording records data of this method on the chart paper.
Printer Recording
Input data is printed directly on the chart paper at high speed (100mm/s). Waveforms are displayed as if recorded with a pen on the display, and the input module and chart speed can be set. 48ch signals can be printed on the chart paper.
In addition, as the data printed on the chart paper is also stored digitally on the SSD, the data can be printed out later, even if the chart paper run out,
Recording Specifications
Chart speed: 1kS/s (100mm/s) to 10S/s (1mm/min)
Recording resolution: 10 to 40 dots/mm (time axis) 8 dots/mm (amplitude axis)
Chart Speed
The chart speed can be changed while monitoring the signal.
■ Input Modules
