Key features include direct PC or laptop interface with software for single and time-activated measurement (data acquisition) modes, software-based calibration mode, and stand-alone operating modes (no PC or other circuits required) as well as direct LCD/VFD Display module interface (MB203 series). In addition, Multiple Display Sets with different Range display settings or different Unit display settings are available and easy to program by the user. The ALD MB1 and MB200 series of DVM modules are shipped ready to be mounted and used, and yet at the same time offers a variety of user options in a compact and economical package. These boards are classified into three main categories of usage, known as Mode A, Mode B and Mode C.Mode A is used primarily for measurements against a calibrated reference voltage typically required in precision voltmeter applications. Mode B is intended for measurements against a ratio-metric reference voltage such as those required in weigh scale (bridge sensor) applications. Mode C is used for display applications and can be programmed to be compatible with most industry standard serial binary input data formats - up to 31 serial bits plus sign bit. The serial digital data can come from another microprocessor or directly from a data converter. Key on-board options include provisions for input voltage scaling, input preamplifier, two-channel multiplexer, and a variety of display modes on the PC screen or LCD/VFD display module. |
