2.3 First Operation
Warning
Prior to switching on your TED4015, please read the safety instructions in chapter
carefully.
Turn on the unit by means of the line switch (F1 - see section
Operating elements at the front
).
After switching on the unit, the backlight of the display (F2) must get visible and the backlight
behind the adjustment knob (F6) must light up.
If nothing is shown on the display, please check the line voltage (see chapter
) and the mains fuses (see chapter
).
The TED4015 is immediately ready to use after turning on. The rated accuracy is reached,
however, after a warming-up time of approx. 30 minutes.
After switching on the unit, the graphics display will show the device status, followed by the
measurement screen.
By using the softkeys (F3) you can select the menu items, the set values and the measurement
values to be displayed. You can change the set values by pressing the
Modify
button or the ad-
justment knob and then turning the adjustment knob (F6). Push this knob or the
Done
key to
enter the adjusted value. If several menu items are displayed, you can select them also by turn-
ing and then pressing the adjustment knob.
If changing a parameter isn’t permitted in the actual operating mode, or you arrive at the end of
a parameter number range, entering is declined and a short beep is audible.
From any menu level, you can navigate to the next higher menu level using the
ESC
key (F4).
The highest level is the measurement screen.
To leave the measurement screen and to enter the menu, press the
Menu
key or the
ESC
key.
