Model 2410 SourceMeter

The general operating boundaries for the Model 2410 are shown in
drawing, the 1A, 20V and 20mA, 1kV magnitudes are nominal values. The actual maxi-
mum output magnitudes of the SourceMeter are 1.05A, 21V and 21mA, 1.1kV. Also note
that the boundaries are not drawn to scale.
These operating boundaries are valid only if the SourceMeter is being operated in an envi-
ronment where the ambient temperature is 30˚C or less.
NOTE Above 30˚C, high power operation could overheat the SourceMeter, causing the
output to turn off. See
tions to avoid shutdown," page
The heavy solid lines show the limits for continuous output operation. Note that in quad-
rants II and IV (sink operation), the limits for the 1A range are derated as follows:
1A Range – Limits linearly derated from:
If the output duty cycle is decreased to 60% or less, sink operation limits are restored to
normal as shown by the dotted lines in
cooling period.)
