Page 14: Measuring/Testing
In order to avoid undesired shutdown of defective devices under test, the electrical circuit for the DUT should be separately fused. Before connecting the AT3-III E to the mains, the test instrument must first be connected to the AT3-III E. ... -
Page 15: Measuring Protective Conductor Resistance
If the AT3-III E/AT3-III CH is not used for a lengthy period of time, the protective surfaces on the plug connectors and the connector plug (13) may corrode, resulting in slightly higher resistance readings. If this is the case, insert and remove the plugs several times until the expected values are restored. - Page 16 Disconnect the AT3-III E/AT3-III CH from the mains in order to restart. Reconnect the AT3-III E/AT3-III CH to the mains. The test adapter is once again ready for use after a brief self-test.
