4 Getting started
4.1 Batteries / Power supply
To insert the batteries, you need a screwdriver. First, the base must be opened, before you can open the
battery compartment of the transmitter. Loosen the fastening screw and remove the cover of the battery
compartment. After that, the battery can be inserted. The receiver unit also has a battery cover, which is
secured with a screw. After the screw is loosened, the battery cover can be removed and the batteries
can be inserted. Once the batteries are inserted, the respective covers must be put back in place and
secured by the screws.
Mind the correct polarity of the batteries when replacing them. If the polarity is not correct this might
damage the device. Also, mind the common guidelines for handling batteries to prevent damage or
injuries. Only use such batteries, as defined in the specifications of this manual. If the unit is not used for
a longer period of time the batteries should be removed to prevent battery leakage.
When the low battery indication flashes on the display, the batteries must be replaced. The device also
gives out an acoustic signal when the battery voltage is low. Please make sure that the device is turned
off and all the test leads are disconnected from the device when replacing the batteries.
4.2 Measurement method
The Cable Locator PCE-CL 20 is a two-part instrument, consisting of a transmitter and a receiver unit.
Additionally, it comes with a variety of measuring accessories.
When locating a cable, the transmitter applies an AC voltage (modulated by digital signals) to the cable or
metal tube to be found, which generates an alternating electric field. When the receiver is held near the
cable or pipe, the electrical field generates a voltage . The receiver can amplify the signal by hundreds of
times. By detecting changes in the signal while moving the receiver, it can detect the position of the cable
or pipe. The cable locator can only detect cables and pipes which are connected to the transmitter
properly. For each application, the connections of the transmitter must ensure a closed circuit.
