ETS-Lindgren HI-4416 Numeric EMF Readout Unit - Manual (Page 18)

18 Operation www.ets-lindgren.com
Once the system readout is turned on, all segments of the LCD will activate for
two seconds, the version of software installed will appear, followed by the current
range of the probe connected to the readout. The HI-4416 then switches to
normal operation (measurement). The LCD readout displays the observed value
and the units of measure.
The bar graph along the top of the LCD window presents an analog
approximation of the measured field. Each bar graph segment represents five
percent of the full-scale reading in the current range. The bar graph is updated
7.6 times per second while the digital display is updated 1.9 times per second.
When the measured field strength is below 5% of full scale for the range in use,
the "Under Range" indicator at the left end of the bar graph appears and the
display will flash on and off. When possible, switch the range to permit a field
strength reading that does not trigger the "Under Range" indicator. If the field
strength exceeds full scale, the "Over Range" indicator at the right end of the bar
graph will appear and the characters “OL” will appear on the display. Select the
next appropriate range.
