Fully Integrate into High-Speed, Multi-channel Measurement Systems The MR8740 uses a two-block internal architecture, essentially giving it the capabilities of two MEMORY HiCORDERs. High-speed isolated measurement Simultaneous 20M sampling within the same block HIOKI company overview, new products, environmental considerations and other Information are available on our website. Digital Voltage Meter Measure minute changes in voltage at a high level of precision. Simultaneous measurement of all channels—rather than scanner-type measurement-dramatically reduces cycle times. Systems Integration

Are you having problems with multi-channel measurement or testing? “We're using multiple DMM units with a scanner to switch inputs. Measurement takes too long…” Reduced cycle times “We can't embed our oscilloscope, so we use it on a shelf. Our setup would be a lot sleeker if we could t it in.” “We need to perform many different types of measurements on a large number of channels.” Measure across multiple channels at the same time “Tall, large racks are dangerous in a production setting. I wonder if our setup can be made smaller…” “We're using multiple measuring instruments, and it's hard to control...
