DMM measurement capabilities
The DMM is not available on the Models 3706-S or 3706-SNFP.
The DMM of the Series 3700A can make the following measurements:
•
DC voltage measurements from
–10 nV to 300 V
•
AC voltage measurements from 100 nV to 300 V
•
DC current measurements from 1pA to 3.0 A
•
AC current measurements from 1 nA to 3.0 A
•
Two-wire resistance measurements from 1
µΩ to 120 MΩ
•
Four-wire resistance measurements from 100
µΩ to 120 MΩ
•
Commonside ohms resistance measurements from 1
µΩ
to 2
kΩ
•
Frequency measurements from 3 Hz to 500 kHz
•
Period measurements from 2
s to 330 ms
•
Temperature measurements from
–200 °C to 1820 °C
•
Continuity testing using the 1
kΩ range
When using a switching module, do not exceed the maximum signal levels of the module.
For information on verification and calibration of the DMM, see
