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. -

„ and to program the alarm thresholds (on the C.A 6524 and C.A 6526). ∆Rel On the C.A 6524 and C.A 6526, the ∆Rel key is used to display the measurement from which a stored reference measurement is subtracted. On the C.A 6524 and C.A 6526, the MEM key is used to record measurements. -
Page 13: Use
1000V The instrument displays the voltage on the terminals. It detects whether the voltage is AC or DC and, if it is AC, displays its frequency (on the C.A 6524 and the C.A 6526). In the MΩ settings, the symbol indicates that the voltage is too high (> 25 V) and that insulation measurements are prohibited. -
Page 14: Insulation Measurement
Pressing the key, before or during the measurement, changes the secondary display unit to display the current (on the C.A 6524 and C.A 6526) or the elapsed time. Press the TEST button and hold it down until the The measurement is displayed on the main display unit measurement displayed is stable. - 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.
