DC AND AC CURRENT MEASUREMENT (See Fig. 3)
❶ Connect red test lead to the A input (ACx for HD115B) for current measurements up to 2A or to the 10A
input for current measurements to 10A. Connect black test lead to COM input connector. ❷ Set the Function
Switch to the desired current range. ❸ Press the AC/DC menu button to display either AC or DC indicator. ❹
Open circuit in which current is to be measured (voltage between this point and ground must not exceed
1000V). Securely connect test leads in series with the load. š Turn on power to circuit being tested. › Read
current value on Digital Display.
Note: If, in the 10A range, the meter is exposed to current greater than 10A, it should be turned off and
allowed to cool for at least 10 minutes
Incorrect Input Warning: A tone will sound when a test lead is connected to either amperage jack, but the
selector switch is not set to the correct current range. Ranges 200mA to 2A require the test lead in the A jack
(ACx for HD115B). The 10A range is only for use with the test lead in the 10A jack.
