(N-G) events and to measure the recorder’s polarity, indicated by the LED. Also see below under “Using an Ungrounded Outlet”. The ground prong may be electrically disconnected (as long as it is not exposed). The recorder does not need special ventilation, however, its ambient temperature should not be allowed to rise above the operating limit. (See Chapter 7 “VR101 Specifications”.

Using an Ungrounded Outlet

Plugging the recorder into an ungrounded outlet has the following consequences:

1.Polarity indication by the LED is not valid.

2.Neutral to ground events captured are not valid.

3.If the recorder is plugged in improperly (improper polarity), hot to neutral events captured are shifted 180 degrees and indicated with the opposite polarity.

Polarity Indication

In some countries outlets are not polarized. This means that the recorder can be plugged in improperly (hot and neutral swapped). Improper polarity connection will not cause damage to the recorder but events will not be correctly recorded and the results may cause misinterpretation.

Note 1:

When plugging in the recorder improperly (improper polarity connection), the LED will blink quickly during 8 to 16 seconds (also see Note 2). When plugging in correctly, the LED lights steadily during 8 to 16 seconds. Polarity indication starts from 0 to 8 seconds after plugging in.

Note 2:

The LED on the recorder also blinks when an event is captured, but then it blinks slowly.
