6243/44 DC Voltage Current Source/Monitor Operation Manual
4.1.2 Remote Sensing (2-wire/4-wire Connection)
4-4
NOTE: For 6243, the maximum remote sensing voltage (allowable voltage difference between OUTPUT-
SENSE) is
 0.5 V for both HI and LO sides.
To meet the specified accuracy, adhere to the following restrictions on r
1 to r 4 .
r
1 , r 2  0.5 V/Io []
(Io: Output current)
r
3 , r 4   220 k []
(Vos = r
1 Io, r 2 Io)
(Example) When Io = 2 A
r
1 , r 2  0.5 V/2 A = 0.25 
Assuming r
1 , r 2 = 0.25 
r 3 , r 4   220 k = 4.4 
NOTE: For 6244, the maximum remote sensing voltage (allowable voltage difference between OUTPUT-
SENSE) is 1.0 V for both HI and LO sides.
To meet the specified accuracy, adhere to the following restrictions on r 1 to r 4 .
r
1 , r 2  1.0 V/Io []
(Io: Output current)
r
3 , r 4   220 k []
(Vos = r
1 Io, r 2 Io)
(Example) When Io = 10 A
r 1 , r 2  1.0 V/10 A = 0.1 
Assuming r
1 , r 2 = 0.1 
r 3 , r 4   220 k = 2.2 
