APPENDIX
The CDA 50 is an audible and visual DC and AC
voltage tester. It also has a phase/neutral identi-
fication function. Its maximum operating voltage,
690 V, allows tests on a 3-phase 400 V/ 690 V
installation whilst respecting the max voltage of
600 V in relation to the earth.
This tester does not have a fuse and its design
avoids risks of internal short circuit.
Test prods (with 19 mm gap)
Non-slip guard to avoid any accidental contact
with a live conductor
Ramp of LED's giving the value of the voltage
AUTO-TEST: test button
The auto-test allows testing of the correct operation
of the complete tester: test prods with light emitting
diodes (LED), via the lead, the electronics, the
buzzer and the 9 V battery.
NB: Never use the tester if the auto-test is negative.
How to do the auto-test
Press the AUTO-TEST button
The "+" LED and the 12 to 690 V LED's light
up, and the buzzer is activated.
Short-circuit the test prods, with the AUTO-
TEST button still pressed: the "-" LED lights up
The tester is in good working condition if all the
LED's light. If not, change the 9 V battery (see 6.
Maintenance) and do the auto-test again.
Always do an AUTO-TEST before using the tester.
3.1 HOW TO USE
Hold the tester in your hand, without pressing the
AUTO-TEST button and place the test prods at
the terminals of the circuit to be tested.
The simple presence of a voltage ensures
automatic operation.
