NOTE
Press to set a range for the attenuator circuit (voltage divider circuit).
Input sensitivity is approximately 10% of the selected attenuator range. Check
the signal level with the
V function before measuring the frequency.
Example: The frequency of a 10 V signal can be measured in the attenuator range
of 2 V or 20 V, but not in the attenuator range of 200 V or 700 V.
