3.8. DC CURRENT MEASUREMENT
1. Insert the black test lead banana plug into the negative (COM) jack.
2. For current measurements up to 4000uA DC, set the function switch to
the uA position and insert the red test lead banana plug into the (uA)
jack.
3. For current measurements up to 400mA DC, set the function switch to
the mA range and insert the red test lead banana plug into the (mA)
jack.
4. For current measurements up to 1 QA DC, set the function switch to the
A position and insert the red test lead banana plug into the 10A jack.
5. Press the MODE button until "DC" appears on the display.
6. Remove power from the circuit under test, then open up the circuit at
the point where you wish to measure current.
7. Connect the black test probe tip and the red test probe tip in series to
the circuits current that you want to measure.
8. Apply power to the circuit.
9. Read the current on the display. The display will indicate the proper
decimal point, value and symbol.
3.9. AC CURRENT MEASUREMENT
1. Insert the black test lead plug into the negative (COM) socket.
2. For current measurements up to 10A, set the function switch to the A
position and insert the red test lead plug into the (10A) jack.
3. For current measurements up to 400mA, set the function switch to the
mA range and insert the red test lead banana plug into the (mA) jack.
4. For current measurements up to 10A AC, set the function switch to the
A position and insert the red test lead banana plug into the 10A jack.
5. Press the MODE button. The measurement mode will change between
AC or DC as required.
6. Remove power from the circuit under test, then open up the circuit at
the point where you wish to measure current.
7. Connect the black test probe tip and the red test probe tip in series to
the circuits current that you want to measure.
8. Apply power to the circuit.
9. Read the current on the display. The display will indicate the proper
decimal point, value and symbol.
3.10. RESISTANCE [Ω] MEASUREMENT
WARNING:To avoid electric shock, disconnect power to the unit
under test and discharge all capacitors before taking any resistance
measurements. Remove the batteries and unplug the line cords.
