Resistance Measurements; Capacitance Measurements - Southwire 12070T Instrucciones De Uso

AC and DC Current Measurements cont.
7. Touch the test probe tips in series with the circuit being tested.
For DC measurements, touch the red test probe to the positive side of
the circuit and the black test probe to the negative side of the circuit.
8. Apply power to the circuit.
9. Read the current on the LCD display.

Resistance Measurements

WARNING:
Never test resistance on a live circuit.
1. Set the rotary function switch to the
2. Press the MODE button until "M "
appears on the LCD display.
3. Insert the black test lead into the negative
COM input jack Insert the red test lead into
the positive input jack.
4. Touch the test probe tips across the circuit or
component under test. It is best to disconnect one
side of the device under test so the rest of the circuit
will not interfere with the resistance reading.
5. Read the resistance on the LCD display.
Continuity Test
WARNING:
Never test continuity on a live circuit.
1. Set the rotary function switch to the
position.
2. Press the MODE button until the " " symbol
appears on the LCD display.
3. Insert the black test lead into the
negative COM input jack. Insert the red
test lead into the positive input jack.
4. Touch the test probe tips to the circuit or
wire you wish to check.
5. If the resistance is approximately 30 or less,
an audible tone will sound. If the circuit is above 400 ,
the LCD display will indicate "OL". The resistance will
be shown on the LCD display if it is below 400 .

Diode Test
WARNINGS:
Never test diodes in a live circuit.
1. Turn the rotary function switch to
the position.

2. Press the MODE button until the "
symbol appears on the LCD display.
3. Insert the black test lead into the negative
COM input jack and the red test lead into
the positive input jack.
4. Touch the test probes to the diode under test.
Forward voltage will indicate 0.4 to 0.7V.
Reverse voltage will indicate "OL". Shorted
devices will indicate near 0V and an open
device will indicate "OL" in both polarities.

Capacitance Measurements

WARNING:
before taking capacitance measurements.
1. Set the rotary function switch to the CAP position.
2. Insert the black test lead into the negative
COM input jack and the red test lead into
the positive CAP input jack.
3. Touch the test leads to the capacitor being tested.
4. Read the capacitance value on the LCD display.
The meter will automatically adjust the ranges
between nF, µF, and mF. It may take up to a
minute to get a stable reading on large capacitors.
5. If the symbol dISC appears on the LCD display,
discontinue test and safely discharge capacitor
before retesting.
