ZERO
Transmits a zero command to the probe. This zeroes all ranges and axes, which
includes both sets of sensors, electric, and magnetic fields. It establishes a
baseline for measurements by sampling all axes and ranges and subtracting
those values from each subsequent measurement.
Note: The meter must be zeroed prior to making measurements.
TEMP
Displays the current temperature of the probe in degrees Celsius. Press and
release TEMP and the temperature will display for two seconds, and then the
readout will change back to measurement mode.
Measurement Techniques
Caution: When taking measurements of electromagnetic
fields, there is a potential of exposure to high or
excessive levels of electromagnetic energy. Approach the
energy source slowly and carefully. If extremely high
amounts are present, immediately leave the area.
T AKING M EASUREMENTS
Hold the readout in one hand and the probe in the other. If you know where the
energy source is, approach it slowly, and then point the probe towards it. If you
are not sure where the source is, hold the probe above your head, pointed up at
about 45 degrees. To find where the maximum reading is coming from, rotate the
probe in a circle.
