Description

The MR8740 and MR8741 are rack-mountable data acquisition systems that deliver high-speed, multi-channel measurements over maximum of 32+22 channels. The MR8990 DVM unit is a 2-channel input unit for the MR8740/MR8741 for measuring minute fluctuations in output from sensors in automobiles and other equipment and voltage fluctuations in devices such as batteries at high levels of precision and resolution.

Key Features
• Introducing the DVM Unit MR8990 with high 24-bit resolution! Perform high-speed, high-accuracy measurement without going through a scanner.
• Support for multi-channel measurement (MR8740: up to 54 ch; MR8741: up to 16 ch)
• Isolated input (between input channels; input-to-chassis isolation: maximum input-to-ground rated voltage of 300 V AC/DC)
• High-speed sampling (max. 20 MS/s; with 54-ch type, simultaneous sampling of up to 32 ch)
• Ideal for rack-mounting (4U height/within 180 mm; display-less, box-type design)
• Display waveforms and make settings on a DVI-D connected monitor and mouse
• Remote measurement via LAN using control commands from a PC
*Screen monitoring and remote operation available via Internet browser. For faster and more convenient remote operation, we recommend using the Hioki 9333 LAN Communicator.
