Example 1: Close channel, make measurement using DMM operation method
When you assign a measurement function to a channel and press the
Close
key, the
Close
key
routes the input signal automatically to the DMM through the appropriate backplane relays. This
behavior is referred to as DMM operation.
Figure 46: Close channel and trigger measurement on instrument using the DMM method
1. Assign a measurement function of two-wire ohms to channel 1031:
a. Use navigation wheel to modify the channel designation from
001
to
031
.
b. Use navigation wheel to select
twowireohms
as the measurement function.
2. Press the
CLOSE
key to close channel 1031.
3. Press the
TRIG
key to acquire and display a single measurement.
Voltage measurements (DC volts and AC volts)
The Series 3700A can make DC volt measurements from
–10 nV to 300 V and AC volt
measurements from 100 nV to 300 V
RMS
(425 V peak for AC waveforms).
•
DC volt input resistance: 100 mV through 10 V ranges: more than 10
GΩ
•
100 V and 300 V ranges: more than or equal to 10
MΩ
