Reading The Lcd; Ac Magnetic Field Detection - TriField TF2 Owner's Manual

Reading the LCD

The Field Measurement shows the numerical measurement and units, at the bottom of the
LCD. The Field Measurement is averaged to give the most stable, accurate reading possible. The
Field Percentage Indicator shows a circular bar graph of the percentage of maximum range that
corresponds to the Field Measurement, on a logarithmic scale. The Field Percentage Indicator
has a scale that shows tick marks for 0, 10, 20, 50 and 100 percent of maximum range. The Field
Percentage Indicator is shown above the Field Measurement, in the middle of the LCD.
The Peak Measurement captures the highest peak that has been measured and holds that value
for 3 seconds or until a higher peak is measured. The Peak Measurement can capture peaks
every 12 milliseconds (ms). The Peak Measurement will be shown numerically at the top left of
the LCD, next to the peak icon . The Peak Percentage Indicator shows a circular arc graph
of the percentage of maximum range that corresponds to the Peak Measurement. The Peak
Percentage Indicator uses the same scale as the Field Percentage Indicator and is shown above
the Field Measurement Indicator.
When turning the meter on, please allow 1.5 seconds for the reading to stabilize.

AC Magnetic Field Detection

To measure the 60 Hz-equivalent effect of an AC magnetic field on the human body, turn
the knob to the Weighted MAG setting and hold the meter at whatever location you want to
measure. For standard technical AC magnetic field measurement, turn the knob to the Standard
MAG setting.
The orientation of the meter does not matter while in the magnetic modes, because all 3 axes
are combined. Your body and hand do not shield the magnetic field and do not interfere with
the measurement.
