ADJUSTING THE DISPLAY

Adjusting the Contrast

Use to adjust the contrast of the display to your preference. Note that new contrast adjustment of the display is stored in memory until a new adjustment is made.

Contrast adjustment can also be made after you have

pressed , and you have highlighted the contrast with

, and pressed to select. is then visible in the right bottom of the display.

Using the Backlight

You can set the backlight to high or low intensity. At power- on, the backlight is set to high intensity.

High intensity becomes extra high when the test tool is connected to the line power.

To set the backlight intensity, do the following:

1.Press to set the backlight to low intensity.

If you do not set the backlight to low intensity within 5 minutes after power-on, when the testool is battery powered, the backlight automatically switches to low intensity to save battery power.

If you want to work with a bright display, do the following:

2.Press to set the backlight to high intensity.

The actual power source, BATTERIES or POWER ADAPTER, appears for a moment on the display.

The backlight will now remain at high intensity until you set it to low intensity.

NOTE

Using the backlight at low intensity lengthens battery life.
