DMM measurement capabilities
The DMM of the Series 3700 can make the following measurements:
DCV: DC voltage measurements from -303V to 303V
ACV: AC voltage measurements from 0V to 303V
DCI: DC current measurements from -3.1A to 3.1A
ACI: AC current measurements from 0A to 3.1A
2: 2-wire resistance measurements from 0to 120M
4: 4-wire resistance measurements from 0to 120M.
CS: Common side ohms resistance measurements from 0to 120M.
FREQ: Frequency measurements from 3Hz to 500kHz.
PERIOD: Period measurements from 2s to 333ms.
TEMP: Temperature measurements from -200°C to 1820°C.
CONT: Continuity testing using the 1krange.
CAUTION When using a switching module, do not exceed the maximum signal levels of
the module.
