Intermittent operation limits
The DLRO100 is a high-power instrument and, as such, can generate significant heat. To prevent damage, the instrument contains
internal thermal protection which can disable the test current if excessive temperature rise is detected. In this event, the thermometer
symbol will be displayed on the screen. If this should occur, switch the instrument off and allow it to cool before repeating the test. If
possible, do not position the instrument in direct sunlight.
