MX-5 Ultrasonic Thickness Gauge
The UP arrow key has two functions. When the MX-5is 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 MX-5is not in calibration mode, the UP arrow key switches the SCAN measurement mode on and off. Refer to page 18 for an explanation of the SCAN measurement mode.
The DOWN arrow key has two functions. When the MX-5is 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 MX-5is 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 while the M X-5is making a measurement and turn off after several seconds to conserve battery life.
