1. PRESENTATION

The C.A 1310 is an integrating sound level meter designed to assess ambient sound and noise and compliant with standards IEC61672-1 class 2 and ANSI S1.4 type 2.

It has many professional and home applications: measuring sound levels in factories, schools, o'ces, airports, studios, auditoriums, etc.

The C.A 1310 is a compact portable instrument that can be held in one hand or, for long-term measurements, mounted on a tripod.

The C.A 1310 can measure and record (memory capacity 64,000 values) sound levels from 30 to 130dB.

If the sound levels of interest are uctuating, the equivalent continuous sound level can be determined, with periods ranging from 10 seconds to 24 hours. It has a USB interface for communication with a PC.

It provides two measurement weighting curves, A and C, to allow for the way the sensitivity of the human ear varies as function of sound frequency. Curve A is the curve commonly used in an industrial environment, while curve C is better suited when low-frequency sounds are of interest.

2. PRECAUTIONS FOR USE

2.1. PRECAUTIONS FOR USE OF THE SOUND LEVEL METER

We recommend reading these instructions before any use of the instrument.

■ The sound level meter is a measuring instrument that must be protected from impacts and severe vibrations
■ The microphone in particular must be protected from exposure to water and dust, and must not be stored in a place that is damp and/or too hot
■ We advise against cleaning the microphone

2.2. REMARK CONCERNING MEASUREMENT CONDITIONS

1. If the difference of level between the absence and presence of the sound to be measured is 10dB or more, the influence of background noise on the measurement can be regarded as negligible. If the difference is smaller than this, a compensation correction (see table below) must be applied to the measurement made to allow for the background noise:

Differences of level (dB)	4 5 6	7 8 9 10
Compensation in (dB)	-2.2 -1.7	-1.3 -1	-0.8	-0.7 0

1. The microphone must be placed at a distance from any sound-reflecting surface, such as a wall or a floor, in order to minimize errors due to possible spurious reflections. During the measurement, hold the sound level meter at arm's length in order to avoid reflections from your own body, and also to allow unobstructed propagation of the sound in all directions.
2. Make sure that there is no obstacle between the point of measurement and the source of the noise.
3. Disregard measurement levels that are either too low (sound not significant) or too high (overload).
4. Wind striking the microphone will produce extraneous noise. If the instrument is used in a windy place, it is best to fit the windscreen ball on the microphone so as not to pick up unwanted signals.

4.1. CHOICE OF FREQUENCY WEIGHTING

The human ear is not equally sensitive to all frequencies, so filters are used to weight or correct the measured levels according to frequency. The C.A 1310 provides two correction curves, A and C. The more widely used is weighting curve A, representing "the international average ear". It is the curve generally used to measure noise levels in an industrial context. The C curve is better suited for detecting the presence of a low-frequency noise (if the level measured is higher in the C setting than in the A setting, it means that the signal contains significant low-frequency components); this curve is well suited to measurement in a musical context.

To change the frequency weighting:

(1) Press the SET key to enter the settings mode, then the ◀ or ▶ key to select the weighting. The “dBA” or “dBC” symbol then appears, blinking.

(2) Choose "dBA" or "dBC" using the ▼ and ▲ keys.

Press the key to confirm.

If you want to abort the setting in progress, press the key to cancel.

4.2. CHOICE OF RESPONSE TIME

A response time appropriate to the nature of the noise to be measured (brief noise such as the beep of a horn or the cry of an animal, or prolonged noise such as that of an industrial machine) must be chosen. The C.A 1310 provides two response times:

• FAST (fast response) if the noise is made up of brief pulses or if only the peak values are of interest to you. This is the setting most often used.
• SLOW (slow response) to measure an average sound level.

To change the response time:

(1) Press the SET key to enter the settings mode, then the ◀ or ▶ key to select the response time. The “FAST” or “SLOW” symbol then appears, blinking.

(2) Choose the appropriate response time using the ▼ and ▲ keys.

Press the key to confirm.

If you want to abort the setting in progress, press the key to cancel.

4.3. RECORDING THE DATA

Press the REC key to start recording the values. They will be stored in the instrument's memory. Press the key to stop recording.

Remark: During recording, most of the keys, such as SET or Leq TIME, are deactivated. All of the other settings must be made before starting to record. The screen displays the FULL symbol when the memory is full.

(1) Press the ⬤ key to enter the settings mode, then the ◀ or ▶ key to select the interval. The "Int" symbol then appears and the seconds display blinks.
(2) Set the desired recording interval, displayed in minutes and seconds. Increase or decrease the interval by pressing the ▲ or ▼ key; the maximum interval is 1 minute and the minimum
is "00:01" (1 second). Press the key to confirm. If you want to abort the setting in
progress, press the key to cancel.

4.5. ERASING THE STORED DATA

To empty the memory, switch the instrument off, then press

and hold it down, then press and keep it pressed for at least 5 seconds. The "CLr" symbol is then displayed to indicate that the data have been erased.

Remark:

The battery indicator "displays the remaining battery life. The number of black bars decreases as the batteries are depleted. When the batteries are almost fully discharged, the "symbol

disappears. Press the key. The screen displays the "Lo bat" warning. If the instrument is recording, it stops.
