‘Hi’ and ‘Lo’ Range Selections
Use the ‘Hi/Lo’ button to select the appropriate range. If the measurement is
in the range of 35 to 100 dB, use the ‘Lo’ range. If the measurement is
between 65 and 130dB, use the ‘Hi’ range. For measurements between 65
and 100dB, either range can be used. If the display flashes the OVER icon,
press the range button to toggle the range.
MAX HOLD
In this mode, the meter only updates the LCD when a higher reading than
the one presently on the display is detected. Select MAX HOLD by
momentarily pressing the MAX HOLD button. The meter displays the MAX
icon when in the MAX HOLD mode. Press the MAX HOLD button again to
exit this mode (the MAX indicator will switch off).
DATA HOLD
To freeze a displayed reading, press and hold the MAX HOLD button until
the MAX and HOLD display icons appear. To release the display and
return to the normal operating mode, press and hold the MAX HOLD
button until the MAX and HOLD icons switch off.
Backlight button
The LCD is equipped with backlighting for easier viewing, especially in dimly
lit areas. Press the backlight button to turn the backlight on. Press again to
turn the backlight off. The backlight does not have an automatic power down
function; judicious use will conserve battery life.
