Measuring Dc Current (See Figure 3); Measuring Ac Current - True Rms (See Figure 4) - Amprobe HD160C Bedienungshandbuch

Measuring DC Current (See Figure 3)

1. Set the Function Switch to a current function,
2. If AC is displayed, press the A� button to turn on
3. If the 2A function is not selected and RANGE is displayed, press the RANGE button
to enable auto ranging.
4. Connect the test leads: Red to A�, Black to COM.
5. Turn off power to the circuit being measured.
6. Open the circuit (-X-) in which current is to be measured (voltage between this
point and ground must not exceed 1500 V dc).
7. Securely connect test leads in series with the load.
8. Turn on power to the circuit being measured.
9. Read the display, and, if necessary, correct any overload (OL or -OL) conditions.

Measuring AC Current - True rms (See Figure 4)

1. Set the Function Switch to a current function, μA, mA, or 2A.
2. If DC is displayed, press the A� button to turn on AC.
3. If the 2A function is not selected and RANGE is displayed, press the RANGE button
to enable auto ranging.
4. Connect the test leads: Red to A�, Black to COM.
5. Turn off power to the circuit being measured.
6. Open the circuit (-X-) in which current is to be measured (voltage between this
point and ground must not exceed 1000 V ac).
7. Securely connect test leads in series with the load.
8. Turn on power to the circuit being measured.
9. Read the display, and, if necessary, correct any overload (OL) conditions.
