To ensure long battery life the Ethos 8400 will
automatically power off when standing idle for 3
minutes. To power the Ethos 8400 either return the selector switch to “OFF” and then back to
the test selection or simply press any of the four buttons under the display screen.

  CAUTION
Measurements shall only be carried out on de-energised circuits.
If the tester is connected to a live circuit (25V or greater), the LED will flash red and the
hazard buzzer will sound.Your Ethos 8400 is fully protected but measured RMS voltage
will be displayed on the secondary/lower display. Further testing after this point will be
inhibited.To resume testing, disconnect the test leads and isolate the circuit.
All equipment and appliances should be disconnected from the circuit under test.
Attached equipment may be damaged by the higher voltages applied during testing and
may return an artificially low test result.
There may be capacitance on the circuit being tested.Your tester will automatically
discharge this but do not disconnect the test leads or change tester function until auto-
discharge has completed.
