Discharge Time - 4 Pole System - Chauvin Arnoux C.A 6121 Mode D'emploi

3. Connect the test cable to the instrument and to the tested unit in accordance with figure 22 ; le
above unit S, informing the user that the mains voltage is connected to the MAINS TEST input.
4. Press the START/STOP key to prepare the instrument for the mains
voltage cut-out; Ready is displayed after 1s approx.
5. Pull out the double connection element and wait for the result to be
displayed.
6. Save the displayed result for documentation purposes (refer to the
instructions in chapter 5.2 to save the displayed result).
!
NOTES :
The red TEST ON lamp is on during the measurement (until pulling out
the double connection element and until the TEST voltage has dropped
to 60 V).
The actual voltage is displayed during the measurement, and the
disconnection voltage (see fig.20) is displayed when the measurement
is finished.
∆t < 0.1 s is displayed under the main result and no voltage is displayed
on the right of the display, if the discharge time is less than 0.1 s.
