HIOKI MR8847A Memory HiCorder is a high-speed waveform monitoring and recording devices that can simultaneously measure multiple physical phenomena such as voltage, current, temperature, vibration, acceleration and rotation due to complete isolation between channels and from each channel to the ground.
Key Features
• Supports a wide variety of measurements with a total of 13 plug-in modules
• Generate and record with a single unit
• Direct 1000 V high voltage input testing
• High-speed sampling up to 20MS/s with fully isolated inputs
• 16 analog + 16 logic channels to 64 logic + 10 analog channels
• High-speed sampling with waveform judgement function
• Soil-resistant construction strong against adverse working environments
• Big buttons coated to withstand industrial oil and residue
• Drop-in paper loading and one-touch setup, along with high-speed 50mm/s printing
Basic Specifications
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.
