PR-8

Sonic Tester

The UP arrow key has two functions. When the PR-8

is in calibration

mode, this key is used to increase numeric values on the display. An auto-

repeat function is built in, so that when the key is held down, numeric

values will increment at an increasing rate. When the PR-8

is not in

calibration mode, the UP arrow key switches the SCAN measurement

mode on and off. Refer to page 17 for an explanation of the SCAN

measurement mode.

The DOWN arrow key has two functions. When the PR-8

is in the CAL

mode, this key is used to decrease numeric values on the display. An

auto-repeat function is built in, so that when the key is held down, numeric

values will decrement at an increasing rate. When the PR-8

is not in

calibration mode, the DOWN arrow key switches the display backlight

between three available settings. OFF will be displayed when the backlight

is switched off. AUTO will be displayed when the backlight is set to

automatic mode, and ON will be displayed when the backlight is set to stay

on. In the AUTO setting, the backlight will illuminate when the PR-8

actually making a measurement.
