3-2 Basic DMM Operation Model 2701 User’s Manual
DMM measurement capabilities
NOTE Accuracy specifications for all measurement functions and the Model 7700
switching module are provided in Appendix A.
NOTE For remote operations, you can use the internal web page of the Model 2701 to
send commands, queries, and take readings. See “Internal web page” in
Section 10 for details.
Also, supplied TestPoint Runtime start-up software can be used to control the
2701. See Section 4 in the Model 2701 Instrument Networking Instruction
Manual for details.
WARNING The Model 2701 measurement inputs are rated measurement
Category I. The equipment cannot be connected to circuits with
transients greater than 4kV peak. Do not connect measurement inputs
to measurement Category II, III, or IV circuits.
The DMM of the Model 2701 can make the following measurements:
DCV — DC voltage measurements from 0.1µV to 1000V.
ACV — AC voltage measurements from 0.1µV to 750V.
DCI — DC current measurements from 10nA to 3A.
ACI — AC current measurements from 1µA to 3A.
Ω2 — 2-wire resistance measurements from 100µΩ to 120MΩ.
Ω4 — 4-wire resistance measurements from 100µΩ to 120MΩ.
FREQ — Frequency measurements from 3Hz to 500kHz.
PERIOD — Period measurements from 333ms to 2µs.
TEMP — Temperature measurements from -200°C to 1820°C.
CONT — Continuity testing using the 1kΩ range.
CAUTION When using a switching module, do not exceed the maximum signal
levels of the module. To prevent damage to the Model 7700 switching
module, do not exceed these maximum signal levels:
Channels 1-20: 300VDC or 300V RMS (425V peak) for AC
waveforms, 1A switched, 60W, 125VA
Channels 21, 22: 60VDC or 30V RMS, 3A switched, 60W, 125VA
For the other switching modules, the maximum signal levels are
included with their specifications.
NOTE This section shows DUT connections to the front panel inputs of the Model 2701
and to the Model 7700 switching module. Details on Model 7700 connections
are provided in Appendix B.
