Agilent 34401A Service Guide.pdfIEC Measurement Category II includes electrical devices connected to mains at an outlet on a branch circuit. Such devices include
most small appliances, test equipment, and
other devices that plug into a branch outlet
or socket. The 34401A may be used to make
measurements with the HI and LO inputs
connected to mains in such devices, or to
the branch outlet itself (up to 300 VAC).
However, the 34401A may not be used with
its HI and LO inputs connected to mains in
permanently installed electrical devices
such as the main circuit-breaker panel,
sub-panel disconnect boxes, or permanently
wired motors. Such devices and circuits are
subject to overvoltages that may exceed the
protection limits of the 34401A.
Note: Voltages above 300 VAC may be measured only in circuits that are isolated from
mains. However, transient overvoltages are
also present on circuits that are isolated
from mains. The Agilent 34401A are
designed to safely withstand occasional
transient overvoltages up to 2500 Vpk. Do
not use this equipment to measure circuits
where transient overvoltages could exceed
this level.

針對嵌入式產品程序更新問題,提出了一種基于IAP技術的STM32單片機在線固件升級方案,設計了STM32單片機最小系統硬件電路和USB轉串口通信電路,并給出了Bootloader程序、APP程序、PC上機程序的實現流程.實驗結果表明,該方案具有簡單實用、穩定性高、維護成本低和設備使用效率高的特點,適用于嵌入式產品升級.For the problem of updating embedded products program,an online firmware upgrade scheme of STM32 single chip microcomputer based on IAP technology is proposed.This scheme not only elaborates the principle of IAP technology in detail but also provides the design of the minimum system hardware circuit of STM32 MCU,the design of USB for serial communication circuit,and the implementation flow of Bootloader program,APP program and PC program.The experiment results show that the scheme is simple,practical and highly stable.In addition,it can be used to actual embedded product upgrading,significantly reducing Maintenance costs and improving the efficiency of equipment.
