RANGE
The range determines the full-scale setting of the bar graph display
located on the front panel digital readout for a continuous analog
indication of the measured leakage level. The four ranges have
full-scale indications of 1, 2, 5, and 10 mW/cm 2 ; the digital display will
always indicate any value between 0 and 9.999 mW/cm 2 . When set to
auto-range, the best range for each measuring condition will
automatically be selected.
For more information on auto-range, see page 31.

 With no RF input, the instrument will shift to the 0 –1 mW/cm 2 scale.
 When the displayed value exceeds 95% of full scale, the next higher
scale is automatically selected.
 While the digital reading will always indicate any value up to
9.999 mW/cm 2 , the bar graph display will change to reflect the correct
percentage of the newly-selected range. When the displayed value
drops below 30% of full scale, the next lower range is selected.
 If the unfiltered RF signal from the probe exceeds 20 mW/cm 2 or the
filtered RF signal exceeds 10 mW/cm 2 , the HI-1710A will indicate an
over range condition by sounding a continuous beep. The over range
condition will remain until the filtered RF signal drops below
10 mW/cm 2 .
