10.3  

Measuring point scans and Output 

Measuring point scans can be used  to  acquire 
the measured values of all measuring points at 
particular  times,  either  manually  or  cyclically 
over a period of time, which means to store or to 
record on computer (s. man. 6.5). 
For this purpose, the menu 

 Data logger 

, e.g., is 

available: 
 

10.3.1  

Single  Output  /  Storage 

of all Measuring Points 

Single manual measuring point scans for acquir-
ing the momentary measured values of all active measuring points 

(s.man. 6.5.1.1)

 

can be triggered by the key 

 

<MANU>

 

. If the true time of day has to be indicated, 

it must first be set (s. 11.1.1). The output format can be set in the function 

 Cycle 

Timer 

 (s. 10.3.2). 

Single manual measuring point scan:

 

 

<MANU>

 

The following symbols will, 

for a short period,

 be indicated in the 

status line

The start arrow will light up and then go off again

Indicated when measured values are being stored (s. 11.1.2) 

´

REC 

´

 

Each time the key is pressed again after this, the measured values are equally 
processed with the corresponding measuring time. 

10.3.2  

Cyclic  Output  /  Storage  of  all  Measuring 

Points 

For cyclic outputs of measured values (s. man. 6.5.1.2) and recording, the cycle 
and  the  output  format  have  to  be  programmed.  The  measurement  can  be 

started

 by pressing the key 

 

<START>

 

 and 

stopped 

with the key 

 <STOP> 

. At 

each start of a measurement the max, min and average values of all measuring 
points are cleared, if the device has been correspondingly configured (standard 
setting, s. 11.5.8). 
The function 

Cycle Timer 

 indicates the cycle as long as a measurement has not 

been started. After selecting the function (s. 9.4), the cycle can be entered im-
mediately (s. 9.5). After starting a measurement you can see the timer counting 
down to the next cycle. 
Function

     Cycle (

hh:mm:ss

), Memory On, Format List 

 

The key 

 <FORM> 

 can be used as the quickest way to set the required Output 

Format (printouts s. man. 6.6.1).
