severe requirements of reliability and availability corresponding to
industrial and domestic permanent installations (c.f. IEC 664-1).
■Use indoors in environments of degree of pollution at most equal
to 2 (c.f. IEC 664-1), of temperature from 0 to +55°C and of relative
humidity from 20 to 90%.
■Respectthevalueandthe typeoffuses orthereis ariskof damage
to the instrument and cancellation of the warranty.

- Fuse 10 A HBC (6.3 x 32 mm - 500 V - 10 kA)
■Use accessories in conformity with safety standards (NF EN 61010-
2-031) of minimum voltage 1000 V and overvoltage category III.
■Before any measurement, check the leads and the switch are in
thecorrectposition.Whentheorderofmagnitudeofameasurement
is not known, place the selector switch on the highest range then
lower progressively, if necessary, to the appropriate range.
■Never measure resistances on a live circuit.
■For current measurements (without current clamp), switch off the
power supply of the circuit before connecting or disconnecting
your multimeter.
■Toopenthebatterycompartment,theleadsmustbedisconnected.
■Never connect to the circuit to be measured if the battery
compartment is not correctly closed.

CONTENTS
1 - PRESENTATION
TheanalogueanddigitalC.A5011multimeter isdesigned forthedaily
needs of professionals in electricity. It gives the true rms (TRMS)
value. It has the following functions:
- Voltmeter: voltage measurements (V DC and AC)
- Ammeter: measurement of currents (A DC and AC)
- Ohmmeter: resistance measurements (Ω)
- Continuity sound test [ ]
- Diode test ( )
- Frequencymeter (Hz)
It also allows the measurement of decibel levels (dB), on the AC
voltmeter ranges. Its digital display has backlighting ( ), gives the
max (MAX) values and allows the last measurement to be held in
memory (HOLD).
The dial has a fuse test light (Fus.) and “Voltest” light to check the
absence of voltage on ohmmeter.
NB: Always use accessories suited to the voltage and the
overvoltage category of the circuit to measure (to NF EN 61010).

15
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).

2 - DESCRIPTION
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.

6 - DC AND AC CURRENTS
Always switch off the circuit to test before connecting the
multimeterto thecircuit. Ifthe “Fus.”light comeson, changethe
faulty fuse(s) (Reminder: minimum voltage of 100 V).
Connecttheleads tothemultimeterandconnect inseriestothe
circuit with:
- the red lead in the "µmA", terminal, up to 1 A
- the red lead in the "10 A", terminal, from 1 A to 10 A
- for the rms value (See in Ch.3)
-MAX for the maximum value
-HOLD to hold in memory
- for display backlighting
5 - DECIBELS
■Reminder. The measurement of an AC voltage can be expressed
in decibels (symbol dB). The decibel is the ratio of two quantities or
levels.LevelN,in dB,ofavoltageUhasthemathematicalexpression:
U0 is the reference voltage of 0.775 V AC for a power P0 of 1 mΩon
a load of 600 Ω.
■Use. Zero level of the red scale in dB corresponds to U0 = 0.775 for
the 4 V AC range. The reading is direct in dB for the 5 V AC range, on
analogue only, from -20 to +16 dB.
The digital display indicates the value of the voltage in volts.
For the other analogue ranges:
●500 mV : subtract -20 dB
●50 V : add +20 dB
●500 V : add +40 dB
●1000 V : unusable

■Analogue reading: to get the resistance in Ω, multiply the reading
on the 50 scale by the reading coefficient shown in the table.
7 - RESISTANCES
Never test a resistance on a live circuit.
If the “Voltest” light comes on, presence of a voltage U > 10 V
AC/DC. Unplug the leads immediately and cut off the voltage
before making the resistance measurement.
■Connect to the terminals of the circuit or the component to test.
Do not use the A AC input on unprotected current
transformers
