8.       Measurement 
 
8.1     Switching the device on 
 

Press the <ON/ENTER> key 
 

 
8.2     Self-test when switching on 

 
When the device is switched on, a self-test of the digital and analogue circuitry is 
conducted.  The  operational  device  check  proceeds  automatically  after  it  is 
switched  on.  It  takes  approx.  5  seconds,  after  which  the  unit  is  ready  for 
measuring. 
 
Note: 
If  it  becomes  obvious  during  the  test  that  one  of  the  device  functions  does  not 
correspond to the required settings, <SERVICE> will appear in the display. 

 

In this case, switch the device off. 

 

 Please  call  Diaglobal  GmbH  service  (Tel.  +49 (0)  30  6576  2597)  or  contact  your 
specialist retailer. 

 
 
8.3     Test selection 
 

Press the <ON/ENTER> key. 

 

 
The desired test is selected from the menu with the right or left arrow key: 
 
HB - HB-SLS - ERY - HCT - BIL - BIL N - ABS546 
 
Pressing the right arrow key activates the next test  while pressing the left arrow 
key  returns  to  the  previous  test.  The  selected  test  is  shown  in  the  upper  right 
corner of the display. 

 

Confirm test selection with the <ON/ENTER> key. 

 
 
8.4 

Switching the device off 

 

 

 

To switch the device off, press both arrow keys simultaneously. 

 
 
8.5

 

Integrated operational device checks 

 

 

Self-test when switching on 

Testing  of  the  digital  and  analogue  circuits  of  the  device  is  automatically 
performed by the device when it is switched on. 
Please see chapter 8, point 8.2. 

 

 
Differential measurements 

All  measurements  are  based  on  differential  measurements.  I.  e.  after  selecting  the 
desired  test,  the  device  requests  a  zero  measurement  with  a  blank  value  cuvette. 
This creates a reference base to the measured value so that minor deviations can be 
compensated.
