TERMINALS
Ø 4 mm safety terminals
„ COM : common, terminal that receives the black lead
„ V W Hz : terminal that receives the red lead for voltages, resistances, diode
test and frequencies.
„ 10 A : terminal that receives the red lead for the 10 A ranges
„ µmA : terminal that receives the red lead for the μA, mA and 1 A ranges

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).

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

«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.

«Voltest» LIGHT
Voltage presence light on ohmmeter.
If the «Voltest» light comes on: presence of a voltage U > 10 V
Unplug the leads and cut off the voltage before making the resistance
measurement.

SWITCH
Switch with 21 positions to select the functions and ranges and the OFF position.

CONTROL KEYS
NB: These secondary function keys are shown on the digital display.
To swith on and off the display backlight.
NB: Auto off after 6 minutes.
