High speed 1 MS/s simultaneous sampling with isolated input

GL2000 is equipped with an isolated input mechanism to protect signals from interferences caused by noise from other channels. 16-bit A/D converter adopted to achieve hi-speed and hi-resolution measurement.


Simultaneous sampling
GL2000 utilizes simultaneous sampling to eliminate slowdown in sampling rate by using multiple A/D converters in simultaneous sampling method. Four individual A/D converters in each channel sustains the maximum sampling speed for all four channels to measure high speed rapid voltage fluctuation and multi-channel vibration measurement.
Sampling interval: 1 µs to 1 min (in steps of 1, 2, 5)

External sampling function
Sampling of the logger is performed in sync with an external device using an external signal input.
Maximum input frequency: 100 kHz    * B-513 Input/Output cable for GL is required.

 

Multifunction input with CAT III measurement category

Voltage, temperature, humidity, logic and pulse measurements can all be taken simultaneously in high speed.

CAT III 600 V is compatible with measuring power supply circuit in an equipment that captures power directly from the distribution panel.


Measures abnormalities in a repeated waveform by effectively measuring the corresponding RMS value

  • In 1000 Vrms range, Crest Factor is up to 1.41
    * Maximum rated safety voltage: 600 V rms, Peak voltage: 850V
  • In other range, Crest Factor is up to 2.0
