Measuring current
The Model 2016 can make DCI measurements from 10nA to 3A and ACI measurements from
1µAm to 3A RMS.
NOTE See the previous discussion about crest factor in “Measuring voltage” in this section.
Connections
Assuming factory default conditions, the basic procedure is as follows:
1. Connect test leads to the AMPS and INPUT LO terminals. The front inputs must be used;
place the INPUTS button in the FRONT position.
2. Select the measurement function by pressing DCI or ACI.
3. Pressing AUTO toggles autoranging. Notice the AUTO annunciator is displayed with
autoranging. If you want manual ranging, use the RANGE ▲ and ▼ keys to select a
measurement range consistent with the expected current.
4. Connect test leads to the source as shown in Figure 2-5.
CAUTION Do not apply more than 3A, 250V to the input or the AMPS fuse will
open-circuit.
5. Observe the display. If the “OVERFLOW” message is displayed, select a higher range
until a normal reading is displayed (or press AUTO for autoranging). Use the lowest
possible range for the best resolution.
6. Take readings from the display.
Caution: Maximum Input = 3A DC or RMS
