7. Current measurements up to 3 A 

 

The ESCOLA 100 may NOT be used 
to measure circuits connected directly 
to  low-voltage  mains  sources.  See 
page  2  of  “Measurement  categories” 
as specified in DIN EN 61010-1. 

 

The  nominal  voltage  of  the  current 
source may not exceed 600 V. 

 

The multimeter is to be connected 
in series with the load on the side 
where the voltage  with respect to 
ground is lowest! 

 

Turn off the circuit before the Es-
cola  100  meter  is  connected  into 
it. 

 
 

 

 
 

 

If measurements are made when the magni-
tude of the variable is unknown, always select 
a large measuring range before shifting down 
to lower ones. 

 

Connect the terminal at the lower potential to 
the common/ground socket. 

 

Connect  the  common/ground  lead  first  and 
only then the signal lead. 

 
 

7.1  DC currents up to 3 A: 

 

Set the four-way switch to 

 

Alternatively, if measurements are to be made 
with the zero point in the centre, then set the 
four-way switch to 

 

Select  the  required  current  measuring  range 
to a range measured in mA or A. 

 
 

7.2  AC currents up to 3 A: 

 

Set the four-way switch to 

 

Select  the  required  current  measuring  range 
to a range measured in mA or A. 

 

8. Current measurements up to 10 A 

 

The ESCOLA 100 may NOT be used 
to measure circuits connected directly 
to  low-voltage  mains  sources.  See 
page  2  of  “Measurement  categories” 
as specified in DIN EN 61010-1.

Turn off the circuit before the Es-
cola  100  meter  is  connected  into 
it. 

 
 

 

 
 

 

Set up a measuring range of 10 A. 

 

Connect the terminal at the lower potential to 
the common/ground socket. 

 

Connect  the  common/ground  lead  first  and 
only then the signal lead.
