XS user manual v0.55  - 14 - 
1 µA current resolution (OPTION 116-00) 
 
Add of a new range of current measure between 0 and 999 µA. 
 
Value display 
   
  From 0 a 999 µA, display in µA 
  over 999 µA, display in mA  
 
Threshold set up 
 
With or without the option, the ΔI threshold can be set from 1 mA ±10 % to 10 mA ± 10% by 1 mA 
step. 
 
IMAX, IMIN and FIMAX threshold can be set from:  
  0 to 999 µA by 1µA step 
  1mA to 9.99mA by 0.01mA step. 
Current measure 
-   In AC :  
  ±(2.5% + 3 U)    U = 1µA for measures between 0 and 200µA 
  ±(2% + 2 U)    U = 1µA for measures between 200 µA and 1mA 
-  In DC : 
  ±(2% + 2 U)    U = 1µA 
   
 
Display of the value on a 999 points digital indicator. 
In VDC accuracy is given for resistance loads > 1 M.
