1587/1577 Users Manual Measuring AC or DC Current XWWarning To avoid personal injury or damage to the Meter: • Never attempt to make an in-circuit current measurement when the open-circuit potential to earth is > 1000 V. • Check the Meter's fuses before testing. See Testing the Fuses later in this manual. • Use the proper terminals, switch position, and range for your measurement. • Never place the probes in parallel with a circuit or component when the leads are plugged into the current terminals. Turn power OFF to the circuit under test, break circuit, insert Meter in series, turn power ON. To measure ac or dc current, set up the Meter as shown in Figure 12. 22
