Thank you for purchasing the 701941/701942 miniature passive probe.

This 701941/701942 miniature passive probe is designed for user’s safety and 

excellent easy-to-use operability. The probe tip utilizes a spring mechanism to 

minimize the stress applied to a device to be inspected. Additionally, this spring 

mechanism is also effective to prevent the probe tip from slipping on the board 

surface. In particular, the spring mechanism is useful when using the probe 

with it inclined. The probe tip is changeable. Replacement tips are provided 

in the accessory pack. For details about how to change the probe tip, see 

“Maintenance.” A wide variety of optional accessories is available upon request.

To ensure correct use, please read this manual thoroughly before beginning 

operation. After reading this manual, keep it in a convenient location for quick 

reference in the event a question arises during operation.
