4.2 Trouble-shooting guide

Vast majority of service queries relate to malfunctions when switching device on, malfunctions
when using touch screen or error messages when performing a measurement. It is only in rare
cases that these malfunctions are caused by broken hardware. The following chapters provide
a step-by-step guide for trouble-shooting.

4.2.1 Trouble-shooting when switching device on

a) The device cannot be switched on

If  the  device  cannot  be  switched  on,  connect  the  power  adapter  to  a  plug  and  check
whether the green LED lights up on the upper side of the power adapter. Now connect the
12V  charging  cable  to  the  device.  If  the  device  now  switches  on,  check  whether
rechargeable  batteries  are  inserted  (see  chapter  2.3

“Inserting and charging the

rechargeable batteries

b) The device switches off again immediately

If  the  device  switches  off  again  immediately,  the  rechargeable  batteries  are  likely  to  be
discharged.  Connect  the  12V  charging  cable  to  charge  the  batteries.  Check  whether  the
power  supply  unit  is  receiving  current  (green  LED  on  top  of  the  power  adapter  lights  up).
You  can  use  the  device  while  it  is  being  charged.  To  do  so,  simply  switch  the  device  on
while the 12V charging cable is connected.

4.2.2 Malfunctions when using touch screen

a) Screen switches off suddenly

To save power, the device automatically switches the screen off after some time. Touch the
screen to activate it again. If the screen is not activated by touching it, the device has
switched off automatically. Simply switch it back on again by pressing the On/Off button.

Define in Basic settings after how many seconds the device should automatically
switch off the screen and after how many minutes it should automatically switch off
itself (see chapter 4.1.2

“Customize basic settings”).
