Current measurements
Assuming “BENCH” reset conditions, the basic procedure is as follows:
1. Connect test leads to the AMPS and INPUT LO terminals. Either the front or rear inputs
can be used; place the INPUTS button in the appropriate position.
2. Select the measurement function by pressing DCI or ACI.
3. The AUTO annunciator indicates that autoranging is enabled. If you want manual rang-
ing, 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 5.
CAUTION Do not apply more than 2.1A, 250V to the input, or the amps fuse will blow.
5. Observe the display. If the “Over o w” message is displayed, select a higher range until
a normal reading is displayed. Use the lowest possible range for the best resolution.
6. Take the reading from the display.
