Table 4.2: The SM2060 has 26 apertures available, ranging from 5 Seconds to 625uSec
. The table contains all
available measurement apertures and corresponding minimum read intervals and measurement rates.
4.6 RTD Temperature Measurement (SM2064)
For temperature measurements, the SM2064 measure and linearize RTDs. 4-wire RTD can be used by selecting the
appropriate RTD type. Any ice temperature resistance between 25
Ω
and 10 k
Ω
can be set for the platinum t
RTDs. Copper RTDs can have ice temperature resistance values of 5
Ω
to 200
Ω
. The highest accuracy is obtained
from 4-wire devices, since this method eliminates the error introduced by the r
ype
esistance of the test leads. The
onnection configuration for RTDs is identical to 4-wire Ohms.
r allows monitoring of the DMM’s internal temperature. This provides the

4.7 Internal Temperature (SM2064)
A special on board temperature senso
means to determine when to run the self-calibration function (S-Cal) for the DMM, as well as predicti
performance of the DMM under different operating conditions. When used properly, this measurement can enhan
the accuracy and stability of the DMM. It also allows monitoring of the PC internal temperature, which is important
for checking other instruments in a PC-based test system.
4.8 Diode Characterization
Diode measurement function is used for characterizing
display a semiconductor device’s forward or reverse voltage. The DMM measures diode voltage at a selected
current. The available source currents for diode I/V characterization include five DC current values, 100
