PRECAUTIONS FOR USE
This instrument is compliant with safety standard IEC 61010-
2-033, the leads are compliant with IEC 61010-031 and the
current sensor is compliant with IEC 61010-032, for voltages
up to 600V in measurement category III.
Failure to observe the safety instructions may result in electric
shock, re, explosion, and destruction of the instrument and
of the installations.
The operator and/or the responsible authority must carefully
read and clearly understand the various precautions to be
taken in use. Sound knowledge and a keen awareness of
electrical hazards are essential when using this instrument.
Do not use your instrument on networks of which the voltage
or category exceeds those stated.
Do not use the instrument if it seems to be damaged,
incomplete, or poorly closed.
Do not use the instrument in an explosive atmosphere or in
the presence of ammable gases or vapours.
Before each use, check the condition of the insulation on
the leads, housing, and accessories. Any item of which the
insulation is deteriorated (even partially) must be set aside
for repair or scrapping.
Use only the leads and accessories supplied. The use of
leads (or accessories) of a lower voltage rating or category
limits the use of the combined instrument + leads (or acces-
sories) to the lowest category and service voltage.
Use personal protection equipment systematically.
When handling the instrument and test probes, keep your
ngers behind the physical guard.
All troubleshooting and metrological checks must be done
by competent, accredited personnel.

2. USE
This instrument is a digital tester. It measures AC and DC
voltages, alternating currents, resistances, and capacitances.
It also has a continuity function and a diode function and can
be used for non contact voltage detection.
2.1. INSTRUMENT TEST
Before making any measurements, test all of the functions
of the instrument.
To switch the instrument on, turn the switch to any position.
All segments of the display unit light (Figure 6) and the
instrument emits a continuous beep.
If the battery voltage is too low for correct operation of the
instrument, the symbol is displayed.
If the battery voltage is much too low, the display unit
will not light.
In both cases, it is time to replace the batteries (see § 4.2).
With the inputs disconnected, set the switch to W. The
display unit indicates - - - -.
Connect the red probe tip to the +terminal and the black
probe tip to the COM terminal. Bring the two probe tips
together, so that they touch. The instrument indicates a
resistance near zero and emits a continuous beep.
Set the switch to Vand measure a known voltage.
If the results of these four tests are correct, your instrument
is ready for use.
2.2. VOLTAGE
Connect the red probe tip to the +terminal and the black
probe tip to the COM terminal.
Set the switch to V.
Keep your hands behind the guards of the device and of
the test probe (Figure 9).
Place the test probes on the element to be tested and
maintain a rm contact.
The voltage is displayed (Figure 7).
If the voltage is > 30V, the instrument displays , indicating
that the voltage is dangerous.
As default, the instrument is in automatic mode (
SCAN
). If the
voltage is AC, the instrument displays AC. If the voltage is
DC, it indicates DC and displays its polarity.
The Select key is used to exit from the automatic mode (the
SCAN
symbol disappears) and display the AC voltage only, or
the DC voltage only, or to return to the automatic mode.
To determine the type of voltage (AC or DC) for a measure-
ment < 1V, exit from the automatic mode.
Do not use the C.A 757 to check for the absence of a
voltage. For that, use a VAT.

2.3. RESISTANCE, CONTINUITY, DIODE AND
CAPACITANCE
Connect the red probe tip to the +terminal and the black
probe tip to the COM terminal.
Set the switch to W.
Keep your hands behind the guards of the device and of
the test probe.
Place the test probes on the element to be tested (Figure
12). If a voltage is present, the instrument so indicates.
Do not make a resistance, diode, continuity, or capac-
itance measurement on a live circuit.
As default, the instrument is in automatic mode (
SCAN
) and
chooses automatically among the resistance , continui-
ty , diode , and capacitance functions. To force
one of these functions, press the Select key (the
SCAN
symbol disappears).
Resistance and continuity
If the resistance is less than 300 W, the instrument is in con-
tinuity (Figure 11). Below 30 W, it emits a continuous beep.
Between 300 Wand 3 MW, the instrument is in resistance
mode. Above 3 MW, the display unit indicates OL. The 30 MW
range is not available in automatic mode; resistance mode
must be used.
Diode
In diode test, place the red probe tip on the anode of the
diode to be tested and the black probe tip on the cathode.
The instrument indicates the voltage of the diode. If it
is above 2V or if the polarity is reversed, the instrument
displays - - - -.
Capacitance
The 3mF and 30mF ranges are not available in automatic
mode; capacitance mode must be used.
If the device displays dis.C after a measurement, wait for
the end of automatic discharging of the capacitance before
making another measurement.
2.4. CURRENT
Connect the current sensor to the + terminal.
Set the switch to A.
Press on the yellow opening device to open the exible
coil (Figure 13).
Open it and place it around the conductor carrying the
current to be measured (Figure 14) (only one conductor
in the sensor).
Close the coil. To optimize measurement quality, centre
the conductor in the coil and make the coil as round as
possible.
The current is displayed.
