K148
标定是正确测量的基础 因此,你需要对你的放大器进行标定. PC 控制的 K148 能够为你的标定任务提供很高的安全性和可靠性.
良好的精度和线性: K148 模拟应变全桥来标定放大器,zui大8个通道. K148 有5个测量范围 ,每个十个步骤. 其标定直流和载频放大器,范围225 Hz zui大到 4.8 kHz,标定范围为 ?.2 mV/V 到 ?00 mV/V .设备经过很好的平衡,提供了 极高的精度 线性误差为 0.0025%. (直流放大器为0.01%).
通过 PC 进行控制使其有很高的操作安全性: K148 不仅有很高的精度: 并且可节约大量的时间. K148 通过 USB 或 RS232 接口与 PC 进行连接能够实现自动标定. 另外,你可以在PC中设定标定步骤,并可从放大器获得数据,在 PC 机上进行标定.
另外一个优势是当进行多台放大器标定时可以节约大量时间.通过编程,可以设定通道和标定步骤.
采用 USB 接口有更少的配线,并可为 K148 提供电压: 这样就不需要传统的外部电源了.
即使采用 K148 手工标定,有良好设计的按钮,重量轻,且可以和 HBM K800 进行堆叠.

Excellent accuracy and linearity: The K148 calibration unit simulates strain-gage full bridges for amplifiers with one up to eight channels. It comes with five measuring ranges with ten steps each. It enables DC and carrier frequency amplifiers from 225 Hz up to 4.8 kHz with measuring ranges from ±0.2 mV/V up to ±100 mV/V to be calibrated. The calibration unit has been perfectly balanced and provides a uniquely high accuracy and linearity of 0.0025%. (0.01% for DC and carrier frequencies higher 600 Hz ). Operational safety due to setup directly via PC: The K148 calibration unit is not only outstanding for its high accuracy: Save time and gain safety by connecting the K148 to the PC. The K148 is controlled via the USB or RS232 interface and thus enables fully automatic calibration. In addition, you can set the calibration steps directly on the PC and safely acquire the data of the amplifier that is to be calibrated in the PC.
Another plus is that you save time when calibrating systems with many amplifiers. The channels and calibration steps can be programmed to requirements so that verification and calibration take only little time and effort. Using the MGCplus SwiftCal calibration softwareyou can implement an automated complete solution for calibrating MGCplus amplifiers from HBM that is immediately ready for use. Wiring is less complex because the USB port is used for the K148 voltage supply: Inconvenient power packs with wiring and the necessity of having to look for a power socket are history. Even when operating the K148 manually, you get more comfort: The intuitive handling of the device is enhanced by a pleasing design providing easy-to-use push-buttons. The lightweight housing can be accomodated even in confined spaces and can be stacked onto HBM’s K800 calibration unit for strain-gage quarter-bridge amplifiers.
