1. INTRODUCTION
1.1. GENERAL
MiniFlex
®
sensors consist of a flexible coil connected by a shielded lead to a
housing containing the signal processing electronics, powered by batteries. The
flexibility of the sensors allows clamping of the conductor to be measured,
whatever its shape (cable, bar, strand, etc.) and accessibility. The snap-locking
coil opening/closing button allows handling while wearing protective gloves. The
electronic unit can be connected to the mV
AC
or V
AC
input of a measuring
instrument having an input
impedance of ≥ 1 M
Ω
