(*1): push RANGE > 1 sec
*2: Under the RESET (semiauto) or PEAK mode, if press PEAK
> 2 sec, the PEAK function will enter to calibration mode, the
LCD will show "CAL." and the internal buffer will remember
the internal OP offset voltage then back to the manual mode.
Whenever the PEAK function is enabled again, the reading value
will minus the offset voltage, the purpose is to get the real peak
reading.
*3: Under PEAK mode, the bargraph always show current value.
*4, *5: Please see page 16 note 3.
(5) RANGE:
The ranges of voltage, frequency and logic modes is selected by
RANGE pin. The following are the operation flow chart of them.
Voltage mode:
