Test Button Operation; Timed Tests - AEMC 6526 User Manual

The symbol indicates that the instrument is generating a hazardous voltage (>70V).
6. At the end of the measurement, release the TEST button. The instrument stops generating the test voltage and
discharges the device being tested. The

Do not disconnect the leads and do not start any measurement while the symbol
When you release the TEST button, the measurement results remain displayed until the next measurement, or the HOLD
button is pressed, or the instrument is turned OFF.

2.3.2.1 TEST Button Operation

Pressing the TEST button starts an insulation measurement. In normal mode, the test voltage is generated for as long as
the button is pressed. When the button is released, the measurement stops.
In mode, press the test button once to start the measurement, then press it a second time to stop; there is no need to
keep the button pressed. However, if you do not stop the measurement, it will stop automatically after 15 minutes.
In timed test mode (

This locks the TEST button. After you start the measurement, it continues to run without
requiring you to keep the TEST button pressed. The test will run until you stop it, or
when 15 minutes have passed.
This activates timed test mode. You can set a test duration between 1 and 39:59 min-
utes. Use the  and  buttons to modify the value displayed.
When the time duration is displayed, press the  button to enter edit mode. When the
first digit blinks, you can change it using the  button. Press  to go to the next digit
and  to change it. Then press  to validate.
This enables the PI function. This is used to calculate the polarization index (the ratio
of the measurement at 10 minutes to the measurement at 1 minute).
This enables the DAR function. This is used to calculate the dielectric absorption ratio
T1T2
(the ratio of the measurement at 1 minute to the measurement at 30 seconds).
