CHAPTER 1
– How to use TECHKON DENS
1.4 Working with DENS
Switching on and off
The device is switched on by pressing the DENS button and is immediately ready to
measure. DENS will display the last measurement done before turning-off.
If no button is pressed within one minute, the device will switch off automatically.
Switching it on again is easily done with the DENS button. There is no button to turn
the device off.
The precision magnifier is used by placing it on the spot to be checked and pressing
the LENS button to activate the light. As long as the LENS button is pressed the magni-
fier will be lit. This functionality is independent from the DENS being turned on or off.
Charging
The
battery status
is displayed as a battery symbol with three segments in the lower
right corner of the display, when the device is turned on.
When the battery turns empty, the last remaining segment of the battery symbol
starts to flash. In this state several measurements still can be obtained, but it is time to
recharge the battery.
Charging starts automatically by connecting the DENS to a PC or another USB power
source. When the three segments of the battery symbol are indicated statically, the
charging is completed and the battery is fully charged. Up to 10.000 measurements
can be carried out with one battery charge.
Completely charging an empty battery will take approximately four hours. DENS has a
regulated charging management. This means it will power-charge an empty battery,
so the device can be used again after a few minutes. On the other hand, there is no
overcharging of full batteries.
