6. Select averaging.
Use the HI-4416 to select Instantaneous Readings or One-Second
Averaging. The HI-3702 collects a measurement approximately seven times
per second. When the X-axis is selected, each measurement is sent to the
display. When the Y-axis is selected, the one-second average of the
measurements is displayed. The averaging algorithm stores the seven most
recent measurements. Each time a measurement is taken, the algorithm drops
the oldest value, adds in the new value, and then recalculates the average and
sends the new average value to the display.
7. Attach the clamp-on current sensor.
Place the clamp-on current sensor on the arm or leg of the body under test
and close the buckle. For accurate measurements, verify that nothing
interferes with complete closure of the clamp-on current sensor. Make sure no
clothing is caught between the coplanar surfaces of the ferrite core material or
the aluminum housing.
Displayed readings that are less than 10% of the full scale reading for the
selected range are not valid. When Range 1 or Autorange is selected and there
is no current passing through the current meter, a noise floor reading will display.
This is a normal operating condition.
