3.14. Tracing of electric installation
There are two possible manners to trace installation by using the Instaltest 61557
namely:
•
Instaltest 61557 loads installation under mains voltage in a pulsed manner. In
that case, hand-held indicator follows electro-magnetic field, generated around
the loaded conductor.
•
The Instaltest 61557 imposes it’s own test signal to voltage-free installation. In
that case, hand-held indicator follows radiated signal around connected
conductor.
For additional general information concerning the operation, refer to enclosed
handbook
Measurements on electric installations in practice and theory
.
Let’s see the procedure.
Step 1
•
Connect test cable
(Universal test cable or Plug commander) to Instaltest 61557.
•
Set function switch to
