Hioki Memory HiCorders are high-speed waveform monitoring and recording devices that can simultaneously measure multiple physical phenomena such as voltage, current, temperature, vibration, weight, acceleration and rotation due to complete isolation between channels and from each channel to the ground.
| Number of Channels | [8 analog input modules]: 16 analog channels + 16 logic channels (standard)
[5 analog input modules + 3 logic input modules]: 10 analog channels + 64 logic channels (standard 16 channels + 48 channels in logic input modules) * For analog modules, channels are insulated vs. each other and vs. unit ground. For logic modules and integrated standard logic channels, all channels use the unit ground. |
