ments:
Input Range Selection | Main Display | Secondary Display
AC Voltage AC Voltage Frequency
Frequency Frequency AC Voltage
Notes:
© The meter indicates a frequency measure-
ment on the secondary display when you se-
lect the DC/AC A, resistance, diode, or hFE
modes and tum on the dual function. This
measurement is not valid.
* When you select dual measurement while
measuring frequency, the meter selects the
20V AC range for the secondary display. To
measure both the voltage and frequency,
when the voltage is greater than 20V AC,
select AC voltage as the primaiy measure-
ment.
