600V CAT IV 1.6. FUNCTIONS OF THE INSTRUMENT C.A 6522, C.A 6524, and C.A 6526 megohmmeters are portable measuring instruments with digital displays. They are powered by batteries. These instruments are used to check the safety of electrical installations. They are used to test new installations before they are powered up, to check an existing installation in a power-off condition, or again to troubleshoot an installation. -
Page 12: Function Keys
1.8. FUNCTION KEYS In general, the keys have a first function, marked on the key, obtained by a short press, and a second function, marked under the key, obtained by a long press. Function The TIMER key is used to select the , PI, and DAR functions. -

2. USE 2.1. GENERAL At start-up, the instrument indicates the remaining battery If the battery voltage is too low to ensure correct operation life. of the instrument, it so reports. G VHz The batteries must then be replaced (see § 4.2), since the battery life indication is no longer reliable. -
Page 14: Insulation Measurement
2.3. INSULATION MEASUREMENT Ω Set the switch to one of the MΩ positions. Ω 100V Ω 250V The test voltage you should choose depends on the voltage of the installation to be tested. For example, for a network installation at 230 V, insulation measurements 500V will be made at 500 V. - Page 15 2.3.1. OPERATION OF THE TEST BUTTON The TEST button is pressed to make an insulation measurement. The test voltage is generated for as long as the press is maintained. When the button is released, the measurement stops. mode, simply press the TEST button once to start the measurement, then press it a second time to stop; there is no In the need to keep the button pressed.

Page 17: Continuity Measurement
The standard requires that the measurements be made at 200 mA. But a current of 20 mA reduces the consumption of the instrument and so increases its battery life. The C.A 6522 can make measurements only at 200 mA. 2.4.1. COMPENSATION OF THE LEADS To ensure precise measurements, it is necessary to compensate the resistance of the measurement leads. - Page 18 2.4.2. ELIMINATION OF THE COMPENSATION OF THE LEADS To eliminate the compensation of the leads, leave the leads open and long-press the key. > 2s The display indicates the resistance of the leads and the symbol goes off. 2.4.3. MAKING A MEASUREMENT Use the leads to connect the device to be tested to the terminals of the instrument.

2.5. RESISTANCE MEASUREMENT (C.A 6524 AND C.A 6526) The resistance measurement is made with a weak current and can measure resistances up to 1000 kΩ. Set the switch to kΩ. As for a continuity measurement, connect the device to be tested to the terminals of the instrument. The device to be tested must not be live (see §... -
Page 20: Hold Function
If the measured value is less than the stored value, the display becomes negative. Pressing the key displays, in addition, the measured value as a % of the stored value. Rmeas - Rref x 100 Rref In insulation measurements, only the digital display is modified by the ∆REL. The bargraph continues to display the true measured value. -

Page 22: Alarm Function
2.11. ALARM FUNCTION On the C.A 6522, in continuity testing, pressing the TEST key activates the alarm. The symbol is displayed, along with the threshold, which is 2 Ohms. If the measurement is below this threshold and the buzzer is active, the instrument emits an audible signal. -
Page 23: Automatic Stop
On the C.A 6526, the key is green when the alarm threshold has not been crossed and red when it has. In continuity, it is the other way round. This enables the user to check the measurement at a glance. The HOLD key is also used to stop the buzzer after an alarm threshold is crossed. - Page 24 2.13.2. REREADING THE RECORDS Set the switch to MR. The instrument displays the last measurement recorded. Ω Ω 100V Ω 250V 500V MR - 1000V To see the other measurements, press the key.

You can then transfer recorded data from the instrument to the computer. If you turn the switch to an insulation position, you can transmit the measurements in real time. To use the MEG software, refer to its help function. To exit from the Bluetooth connection, long-press the key again, whatever the setting of the switch. -
Page 28: Resetting The Instrument
With the C.A 6524 or C.A 6526, if this occurs during a DAR or PI measurement, the instrument interrupts the measurement and displays the screen shown opposite. 2.15.3. PRESENCE OF A VOLTAGE DURING A CONTINUITY, RESISTANCE, OR CAPACITANCE MEASUREMENT If, during a continuity, resistance, or capacitance measurement, the instrument detects an external voltage in excess of 15 V (AC or DC), it interrupts the measurement and displays the screen shown opposite. -
