SAFETY PRECAUTIONS

■Neveruseonnetworksatavoltageabove1000Vinrelationtothe

earth. This multimeter of overvoltage category III, satisfies the

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 1 A HBC (6.3 x 32 mm - 500 V - 10 kA)

- 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).

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.

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.

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

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
