其中固件版本的BUG就不提了反正以后也可以解决。
硬件问题在这里引用一下
Known Hardware Issues
1. LM317 voltage regulator overheating and causing shutdown
Rigol have "resolved" this issue with a v02.10 board revision as shown in these photos by Dave. Apparently this revised board is shipping in all new units manufactured from roughly Oct/Nov 2013. For units manufactured before that date, Rigol plans to replace units with older boards for free.
>> DIY: A number of users have posted custom fixes, typically replacing the LM317 for an alternate regulator. Refer to this post by ted572 for a professional looking and inexpensive solution ($1.44), which would probably save time as well.
2. Output voltage spikes when unit is turned on
Currently not believed to be resolved by any firmware update or hardware changes. To be safe, best practice is probably not to have anything connected to the power supply when you turn it on.
3. Current sense between channels 2 and 3
Rigol investigated and responded with the attachment "DP832 Recommended Connections.pdf". In brief, Rigol recommend a heavy-duty low-resistance wire between the GND terminals of channel 2 and 3 to reduce the measurement error.
大概意译一下,我英文很差的,多包涵:
第一个是LM317散热不良导致电源重启的问题,这个已经解决了。普源计划为大概出货时间在2013年十一月以前的DP832免费更换2.10版本的顶板。所以2014年的新货肯定是没这个问题了。
第二个是DP832开机时会有一个峰尖电压输出,这可能会造成已连接在电源上的设备被损坏。这个估计没办法通过升级固件或硬件改变来解决,为安全起见,等开机后再把设备连接上去。(但我估计这个问题不止普源才有吧!)
第三个是CH2和CH3之间的电流感应,这个问题普源也给出了一个自己可以DIY的解决方案,下载这个 DP832 Recommended Connections.pdf 看看就知道怎么办了,普源推荐在CH2和CH3的接地端子之间连接一个"重型低电阻丝?"(heavy-duty low-resistance wire我不是专业的哦)呵呵
