Description; Digital-Display - Chauvin Arnoux C.A5011 Bedienungsanleitung

2 - DESCRIPTION

(See drawing in § 15 - APPENDIX)
1 TERMINALS
Ø 4 mm safety terminals
COM : common, terminal that receives the black lead
V Ω Ω Ω Ω Ω Hz
: terminal that receives the red lead for voltages,
resistances, diode test and frequencies
10A : terminal that receives the red lead for the 10 A ranges
µ µ µ µ µ mA : terminal that receives the red lead for the µA, mA
and 1A ranges
2 ANALOGUE DISPLAY
The dial comprises 3 scales:
2 black scales, for all the quantities (0.10 and 0.50),
1 red scale for dB (-20.+16)
NB: This multimeter can be used as a zero galvanometer, as the needle
always moves in the same direction, even for a negative value. The polarity
is shown on the digital display by the appearance of the "-" sign for negative.
So for a value fluctuating around zero, the user has a double scale length
(Scale length 80 mm).
3 DIGITAL DISPLAY
4000 counts (height of digits 7.5 mm)
AUTO : automatic DC/ AC selection
~
: AC
...
: DC
: low battery indicator
Overload indication: "OL" flashes
kHz : reading of the frequency
HOLD : memorised value
MAX : maximum value
4 "Fus" LIGHT
Neon for testing the 1 A and 10 A fuses on current measurement.
If the "Fus." light is lit, change the faulty fuse(s).
NB: This light requires the presence of a voltage ≥ 100 V to come on.
5 "Voltest" LIGHT
Voltage presence light on ohmmeter
If the "Voltest" light comes on: presence of a voltage
U > 10 V AC/DC. Unplug the leads and cut off the voltage
before making the resistance measurement.
