• Do not exceed the maximum rated voltage and current in the measurement category. Do not use your instrument on networks whose voltage or category exceeds that specified.
• Respect the conditions of use, namely the temperature, humidity, altitude, degree of pollution and the place of use.
• When handling the test samples, keep your fingers behind the physical guard.
• Use connection accessories whose measurement category and service voltage are at least equal to that of the installation being measured.
• Do not use the device if it is open, damaged or poorly disassembled, or its accessories if they appear damaged.
• The device must be kept clean so that the condition of the cable insulators, housings and accessories can be checked. Any component whose insulator is damaged (even partially) must be sent for repair or scrapped.
• The device is designed to be used by qualified personnel and in accordance with national safety regulations.
• We recommend wearing personal protective equipment if the environment in which the device is used makes it necessary.

FUNCTIONS
The CA 742 is a voltage detector with lights.
It meets the requirements of standard IEC 61243-3.
The main function of the CA 742 is for the absence of voltage. It detects dangerous voltages, meaning voltages exceeding the ELV (extra low voltage: 50 Vac or 120 VDC).
Its other functions are:

• Indication of a voltage between 12 and 690 Vac or 750 Vdc, with indication of polarity.
• Continuity indication.
• Indication of the phase position.

The voltages indicated on the CA 742 are nominal voltages. Make sure that the device is used on networks on standardized volume

ON THE BACK
When the device is not in use, the test probes can be stored on the back.

USED

This device is a detector. The indications it provides must not be used for measurement purposes.

SELF-TEST
Before using the CA 742, perform a self-test. This checks the integrity of the leads, the correct operation of the electronic circuit, and the battery voltage.
Connect the red test probe to the + terminal and the black lead to the COM terminal.
Touch the 2 test samples together and press the AUTO TEST button. Press as long as necessary.

• If all the indicators of the device except ELV light and the acoustic signal sound, the device is working properly and can be used.

• If all other lights are on, the batteries must be replaced (see §4.2).

• If every third indicator is off, the leads and test samples must be checked. Check that they are properly connected and that the test samples are actually touching, then press the AUTO TEST button again.
  If the problem persists, replace the batteries and try again. If the problem persists with new batteries, the lead and/or test samples must be replaced.

• If no lights are on, replace the batteries (see §4.2). If the problem persists with new batteries, the device is defective and must be sent for repair.

After each check, perform a self-test to confirm correct operation of the device.
In a noisy environment, make sure you can actually hear the device’s audio signal.
Note:  If the AUTO TEST button is pressed for more than 10 seconds, if the test samples do not touch each other, the device will switch to standby.

VOLTAGE DETECTION
Connect the red test probe to the + terminal and the black lead to the COM terminal.
Keep your hands behind the guards of the device and the test probe.

Place the test samples on the item being tested and maintain firm contact.
There is no need to switch on the CA 742, because it starts up automatically.

If the voltage is present:

• AC the indicators light to indicate its value and the + (green) and – (orange) indicators light.

• DC, the indicators light to indicate its value and the + indicator (green) or the – indicator (orange) lights to indicate the polarity.

• dangerous ( >50 Vac or 120 Vdc): the higher the voltage, the faster the ELV indicator (red) flashes; the device also sends audible beeps.

• ELV:  Extra Low Voltage. This redundant indicator shows that the voltage is greater than the ELV.

The first two indicators of the bar graph are green to indicate that the voltage is not dangerous and the device does not beep. The remaining indicators are red and the device beeps.
If only the ELV light is on, the batteries are low or missing.

If there is a disturbing voltage in the vicinity of the element being tested, the device can indicate the presence of an operating volume on the element being tested.

Continuity Detection
Connect the red test probe to the + terminal and the black lead to the COM terminal.
Keep your hands behind the guards of the device and the test probe.
Place the test samples on the item being tested and maintain firm contact.

Keep the button pressed.

If no voltage is detected, the CA 742 performs a continuity test.

• If the resistance is below the continuity limit, indicators 12 to 230 will flash one after the other. The device emits a continuous audible signal.

• If the resistance is above the continuity threshold, the device displays nothing and emits no sound.

PHASE DETECTION
The CA 742 performs unipolar phase detection. This means that connecting a single test probe is sufficient to determine if a phase is present.
Attention:  phase detection cannot replace a lack of voltage test.
To operate properly, the phase detection function must be used on networks that are referred to earth.
It can be used, zBample, to locate the phase at an outlet.
Connect the red test probe to the + terminal
Keep your hands behind the guards of the device
Place the test samples on the element being tested and maintain a firm contact.

If the test probe is actually in phase, the Ph (phase) indicator will flash and the device will beep.

Attention:  if the Ph indicator does not flash, this does not mean that there is no dangerous voltage at the outlet.

USE CA 751 (OPTION)
If you bought a CA 751 2P+T adapter, you can test for the absence of voltage between the phase and neutral on an outlet.
Note:  pairing the CA 742 with the CA 751 derates the combined product to measurement category II, 250V.

Connect the CA 751 to the terminals of the CA 742, then refer to the operating instructions of the CA.751.
