Reading and Changing the parameter value
In order to set the parameter value the following steps should be performed:
–
Select the appropriate LCD mode: ‘show parameter value’
–
Push the left button a long time (a few seconds) until the ‘P’
starts to blink
–
Push shortly to increment the parameter value 1-59, push long for auto
increment.
–
When you have selected the correct value, leave the device untouched.
It will jump to the ‘show measurement LCD mode’ after a few seconds. At that point the
parameter data is stored into the on board non-volatile memory.

Example:
input impedance = 1M Ohm
0..20V (U):
R1 = 818.2k == 820k
R2 = 100k
0..200V (U):
R1 = 9M
R2 = 100k
R1=(f-1)*(R2*Ri)/(R2+Ri)
f = Devidefactor 10, 100 etc
Ri = Input impedance (1M)
