XW Warning
To prevent possible electrical shock, fire, or personal
injury, disregard the bar graph for frequencies >1 kHz. If
the frequency of the measured signal is >1 kHz, the bar
graph is unspecified.
The Product measures the frequency of a signal. The trigger level
is 0 V, 0 A ac for all ranges.
