INTRODUCTION 

Congratulations on purchasing the MFJ-200A Inductance/Capacitancor Meter. The 
Inductance/Capacitancor Meter is highly accurate, compact, rugged, self calibrating, and

 

super easy-to-use! The MFJ-200A delivers laboratory performance. The sophisticated 
high-speed micro-controller allows it to compute unknown capacitance/inductance in 
seconds. Here are some important features we think you'll like: 

Multiple Ranges:

 Four selectable ranges:  

 

 0.01pF - 10uF 

 

 1uF - 100uF 

 

 0.001uH - 100mH 

 

.001mH - 100H. 

Computation: 

High speed Microcontroller precision computation. 

Power: 

Use four AA batteries (not included), 5.5mm DC AC adapter, or any USB source 

with a mini-USB plug.

 

Sleep Mode: 

Intellectually shutdown in 5 min.

 

Just push power switch to resume testing. 

 

 

Important Warnings: 

Do not reset to “0” as components are being measured. If you do it, please shut down 
immediately and restart, then reset to “0”. 

Do not to measure a capacitance which is not discharged, otherwise it may damage the 
mainframe.
