The C.A 6113 installation tester is a portable measuring device with a monochrome graphic display. It is powered by a recharge-
able battery with a built-in charger and external power supply unit.
This device is intended to check the safety of electrical installations. It can be used to test a new installation before it is powered
up, to check an existing installation, whether in operation or not, or to diagnose a malfunction in an installation.
