ADDITIONAL FEATURES

Input Test Lead Warning

The meter emits a continuous tone when a test lead is
placed in the mA or 10A input jack and the Function/
Range Switch is not set to a correct current position. (If
the meter is connected to a voltage source with leads
connected for current, very high current could result). All
current ranges are protected by fast acting fuses.
