CHAPTER 1

INTRODUCTION

  WARNING  

These safety warnings are provided to ensure the safety of person-

nel and proper operation of the instrument.

•  Read this instruction manual completely and follow all the safety 

information before attempting to use or service this instrument.

•  Safety is the responsibility of the operator. The MiniFlex

®

 must 

be  used  only  by  qualified  personnel  using  applicable  safety 

precautions.

•  Wear protective clothing and gloves as required.
•  Use caution on any circuit: potentially high voltages and currents 

may be present and may pose a shock hazard.

•  Read the safety specifications section prior to using the current 

probe. Never exceed the maximum voltage ratings given.

•  ALWAYS de-energize the circuit before wrapping the MiniFlex

®

 

around bare conductors, bus bars, or near live parts. Do not 

wrap on live conductors.

•  ALWAYS  connect  the  electronic  module  to  the  display  device 

before wrapping the MiniFlex

®

 around the sample being tested.

•  ALWAYS inspect the module, sensor, sensor cable, and output 

terminals prior to use. Replace any defective parts immediately. 

Use only factory parts.

•  NEVER use the MiniFlex

®

 on electrical conductors rated above 

1000V CAT III; 600V CAT IV.
