下载U1253B的固件更新时出现问题

我在过去的几天里一直试图为我的U1253B数字万用表（版本2.26）下载最新的固件，但每次点击下载链接时，我都会收到消息：“访问限制。发生意外错误”然后我
重定向到Agilent主页。
有没有其他人有这个问题？
几天前我向安捷伦网站管理员发送了一条消息，但问题仍然存在。
与此同时，固件还有其他来源吗？
谢谢，斯坦

  I'ver been trying for the past several days to download the latest firmware for my U1253B DMM (version 2.26), but every time I click on the download link I get the message: "Access Restriction. An Unexpected Error Occurred" and then am redirected to the Agilent home page. Has anyone else had this problem?

I sent a message about this to the Agilent webmaster a few days ago, but the problem is still there. In the meantime, is there another source for the firmware?

Thanks,
Stan
