Remarks:
3. Operation Instruction of Dual Display Mode:
This function has the same recording mode as that of MAX MIN, but the largest difference
between them is that the response time for the peak (PEAK) record is much shorter
(250μs).
When measuring the actual peak of a sine wave signal, the recording function of the peak
can measure the surge of the power supply much more accurately, the transient value of
surge.
SELECT Button: Press to select function (only suitable for combined range). Long press
SELECT button when powering on the meter, Auto-OFF function can be cancelled.
AC+DC measurement:
In DCV mode, short press SELECT button to enable AC+DC mode: Main display shows
AD+DC value, the secondary display will automatically switch to show ACV or DCV value
with a time interval of 2s.
