Page 8: Setup And Operation
Setup and Operation WARNING: Risk of electrocution. High-voltage circuits, both AC and DC, are very dangerous and should be measured with great care. 1. ALWAYS turn the rotary function switch to the OFF position when the meter is not in use. 2. - Page 9 AC Voltage (Frequency, Duty Cycle) Measurements WARNING: Risk of Electrocution. The probe tips may not be long enough to contact the live par ts inside some 240V outlets for appliances because the contacts are recessed deep in the outlets. As a result, the reading may show 0 volts when the outlet actually has voltage on it.
