The mAcal  now measures the voltage shown in the display. 
 

3.6    HOW NEW PARAMETERS ARE SELECTED (SETUP) 

 

Press 

 

for approx. 2 seconds. The present selection of 
MODE is now shown in the display, e.g.  

 

mA

 

 

          

 

3.6.1  Selection of MODE 

It is possible to choose between 5 different MODES: 



4-20mA LIN 



0-20mA LIN 



4-20mA FLOW 



0-20mA FLOW 



4-20mA VALVE 

 

LIN

 

% calculated linearly. 

FLOW

  - 

% calculated logarithmically. 

VALVE

  - 

% not calculated. 

 

 

AUTO-STEP function 3.8 - 4 - 4.2 - 4..... or 19 - 20 - 21 - 20..... mA.  

 

 

Press 

 

or 

for selection of  new MODE. 

 

 

 

Press

 

to save the present selection. 

3.6.2  Selection of SLOPE TIME 

After MODE has been selected, SLOP TIME (ramp time in the case of AUTO) can be 
changed.  
The text 

 

s

  is shown on the display for approx. 1 second. 

 

 

Press

 

or 

 

for setting of  SLOPE TIME. The time can be 

 

adjusted between 30 - 999 S. 

 

Press 

 

to cancel a selection. SETUP is exited and it is necessary to 
start all over again. This option can be selected at any  time.
