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

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
