Model 2410 SourceMeter

When using the 1A range, you can use the two equations below to determine if the
SourceMeter will overheat. Both of the equations must be true to ensure that the
SourceMeter will not overheat. The result of the first equation must be ≤150 and the result
of the second equation must be ≤120.
1A range power equations:
{[(17 × |I |) - (0.4 × V
OUT
and
| × 42 × DC)] × 1.2} + T
{[30 + (|I

Model 2420 SourceMeter
There are two equations for each of the high power voltage ranges (20V and 60V). Both of
the equations for the selected voltage range must be true to ensure that the SourceMeter
will not overheat. The result of the first equation must be ≤100, and the result of the sec-
ond equation must be ≤85.
20V range power equations:
{[(33 × |I
|) - (V
OUT
and
| × 40 × DC)] × 0.35} + T
{[30 + (|I

60V range power equations:
{[(76 × |I

and
| × 120 × DC)] × 0.35} + T
