○ The measured value is larger than the estimated
value.
Current measurement:
･ Check that you're using the proper range.
･ Examine the waveform using
MON
output function to
confirm that no components but the estimated frequency
are being used.
･ Check that the counter has been reset with
0ADJ/RESET
before peak measurement.
･ Look for magnetic fields, electrical fields or possible noise
sources near the unit.
･ The measured value would be bigger than the actual value
in case that the power supply changes the battery to the
AC adapter such as back from a blackout. (See Chapter 5:
AC Adapter (Optional) )
Voltage measurement:
･ Check that you're using the proper range.
･ Check that the counter has been reset with
0ADJ/RESET
before peak measurement.
･ Look for magnetic fields, electrical fields or possible noise
sources near the unit.
Frequency measurement:
･ Look for magnetic fields, electrical fields or possible noise
sources near the unit.
･ Check the waveform. Some special frequencies can't be
measured, such as those of inverters.
