DESCRIPTION

1 - LIQUID CRYSTAL DISPLAY

I 4000 measuring counts (digit height 10mm)
Rate : 2 measurements/sec
I 40 segment bargraph
Rate : 20 measurements/sec
NB : the bargraph is not operational for frequency and capacitance
measurements
I Automatic display of all the symbols for controls, ranges and functions
I
, low battery indication
I Overload indication :
- the 4 on the left flashes
- arrow at the end of the bargraph

2 - CONTROL BUTTONS

/ ~ and Ω Ω Ω Ω Ω /
: To change from AC (~) to DC ( ) and the reverse,
on voltage and current. To change from continuity (
the measurement of resistance (Ω) and back, on ohmmeter
function.
NB : Automatic selection of ~ and
HOLD : To memorise the last measurement (digital and bargraph).
MIN.MAX : To successively display the min or max values.
The C.A 5220 G then changes to manual range selection.
HOLD is also displayed. Min. acquisition time 500ms.
NB : Press the HOLD button to read the min value
the instrument
RANGE : Range selection : To change from automatic mode to manual
mode. A prolonged press on this button allows you to exit the
manual mode. The automatic mode is selected when the
instrument is switched On.
NB : This button also selects the sensitivity for the frequencemeter function (Hz).
: To switch On and Off the lighting of the display.
NB : Auto Off after 5 minutes.
3 - FUNCTION SELECTOR SWITCH
OFF : Off position
V : DC and AC voltages up to 600V, with high impedance : 10MΩ
V elec : AC voltages up to 600V, with low impedance : 270kΩ
NB : Also available on DC voltage.
Hz : Frequencies of voltages, up to 200kHz
Ω Ω Ω Ω Ω
: Continuity sound test for a resistance ≤ 40Ω, and resistance
measurements up to 40MΩ. The continuity test is selected
automatically when the instrument is swiched On.
: Diode test. Measures the voltage of the junction in forward
direction.
: Capacitances up to 40µF
when it is switched On.
