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.
➎
Turn on power to circuit being tested.
➏
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.
