6. 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 function switch to the OFF position when the meter
is not in use. This meter has Auto OFF that automatically shuts the
meter OFF if 15 minutes elapse between uses.
2. If “OL” appears in the display during a measurement, the value
exceeds the range you have selected.
