4000 measuring counts (digit height 10mm)
Rate : 2 measurements/sec
■
40 segment bargraph
Rate : 20 measurements/sec
NB : the bargraph is not operational for frequency and capacitance
measurements
■
Automatic display of all the symbols for controls, ranges and functions
■
, low battery indication

: To change from AC (~) to DC (
) and the reverse,
on voltage and current. To change from continuity ( ) to
the measurement of resistance (
Ω
) and back, on ohmmeter
function.
NB :
Automatic selection of ~ and when it is switched On.
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
before disconnecting
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.
