1What is in this Guide?
The Operator Guide begins with safety
information, a short meter calibration exercise for
new users, then continues with a condensation of
information from the Operator Manual. For
complete information about the Calibrator’s
features, functions, and operating procedures,
refer to the Operator Manual.
Safety Summary
Warning
[
Lethal voltage may be present on the
terminals. Observe all safety
precautions in this guide.
To avoid electrical shock hazard, the operator
should not electrically contact the OUTPUT HI or
SENSE HI binding posts. During operation, lethal
voltages of up to 1100V ac or dc may be present
on these terminals.
Whenever possible, keep one hand away from the
equipment to reduce the hazard of current flowing
through vital organs of the body.
Symbols Marked on Equipment
[
Warning - Risk of electric shock.
Q
Ground Protective ground (earth) terminal.
P
Attention Refer to the manual for
information about this feature. This symbol
appears on the rear panel ground terminal
and by the fuse holder.
Use the Proper Fuse
To avoid fire hazard, use only the fuse specified
on the line voltage selection switch label.
2Safety Summary (cont.)
[
Grounding the Calibrator
The Calibrator is a Safety Class I (grounded
enclosure) instrument. The enclosure is grounded
through the grounding conductor of the power
cord. To avoid electrical shock, plug the power
cord into a properly wired earth grounded
receptacle before making any connections to the
Calibrator terminals. A protective ground
connection by way of the grounding conductor in
the power cord is essential for safe operation.
[
Do Not Remove the Cover
To avoid personal injury, do not remove the
Calibrator cover. Do not operate the Calibrator
without the cover properly installed. There are no
user-serviceable parts inside the Calibrator, so
there is no need to ever remove the cover.
3P
Fuse and Line Voltage
The correct fuse type for each voltage selection is
indicated on the rear panel as shown in the
following figure.
CAUTION FOR FIRE PROTECTION REPLACE ONLY
WITH A 250V FUSE OF INDICATED RATING.

AIGC您好！FLUKE 5720是一款高精度的多功能电子兆欧表及接地测试仪，专为电气和电子行业设计，用于测量电气设备、电缆线路、电源插座、接地系统等的绝缘电阻（MΩ）、连续性（蜂鸣器检测）以及地线电阻。具体使用说明如下：
1. **开机与关机**：长按Power键开机，显示默认设置。完成测量后，再次长按时关闭仪器。
2. **选择测量模式**：在主屏幕上，通过箭头按键导航至"Ω"或"MΩ"以选择电阻测量模式；选择"GND"进入接地测试模式。
3. **连接测试引脚**：将红色测试探针（L）接触待测导体的正极，黑色测试探针（E）接触负极或设备外壳。对于接地测试，将黑色探针插入专门的地线孔并与大地接触。
4. **进行测量**：启动测量，显示屏会显示出当前所选项目的电阻值。若进行接地测试，当电阻值低于预设阈值时，仪器会发出蜂鸣声表示导通。
5. **读取数据与记录**：等待测量结果稳定后，读取显示屏上的数值，并可选择保存或打印测量报告。
6. **校准与维护**：请参照用户手册定期对FLUKE 5720进行校准，并确保仪器保持干燥、清洁，避免在高温、高湿或磁场强的环境下使用。
请务必详细阅读FLUKE 5720的完整用户手册，以便获得更准确的操作指导和安全注意事项。如有其他问题或需要进一步的帮助，请随时咨询我们。
