Special Symbols - Chauvin Arnoux C. A 6410 Notice De Fonctionnement

SPECIAL SYMBOLS

In addition to the battery service life which is accessible when ON is pressed when
switching on, the clamp can display the battery level at any time:
For an alkaline battery if the service life is less than 25 %: the symbol flashes,
indicating that around 50 resistance measurements can be made with guaranteed
values. If it is less than 20 %: the symbol is continuously displayed, measure-
ments are only indicative, they can not be recorded in the memory.
When the battery is flat, the instrument switches off automatically.
NOISE
This symbol appears when too high a parasitic current (approx. > 5 A ) flows in the earth
conductor (i.e. when the V=IR product is greater than approx. 50 V).
The resistance measurement is then not guaranteed.
This symbol appears when the clamp is open or incorrectly closed. It may be displayed
on the screen when the jaw faces are not perfectly clean.
The clamp can not make a measurement in this case.
R < .1W W W W W
This symbol appears when the resistance measured is less than 0.1 W
OL
This appears on the digital display when the measured value exceeds the measurement
range (1200 W in resistance measurement on all models, 30 A in current measurement
on the C.A 6412, C.A 6415 and C.A 6415R accompanied with an intermittent beep).
