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 µΩto 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 Verification (on page B-1).
