A reading of less than 9.40V at 60°F/16°C indicates a
weak battery. Recharge or replace the battery before
testing.
Dé marcha al motor por 15 segundos después de
desactivar la ignición y verifique el valor mínimo
mostrado.
Una lectura de menos de 9.40V a 60°F/16°C es
indicador de una batería con poca carga. Recargue o
reemplace la batería antes de iniciar la prueba.

Voltage drop tests measure the amount of voltage
expended to overcome resistance (an opposite force
created by a circuit or component to the flow of
electrical current); the lower the voltage drop reading,
the less resistance there is in the circuit being tested.
The Meter has very useful functions (Fix HOLD or
MAX-MIN RECORD) for measuring voltage drops
on many different components and connections.
Measuring the voltage drop across the connections
and components in the starter circuit, while cranking
the engine with the ignition or fuel system disabled to
prevent starting, will indicate if there is a resistance in
the starter circuit.
To measure voltage drop, current must be flowing
in the circuit, and both voltage test probes must be
connected on the same side of the circuit.
Voltage drop can also be determined from available
voltage, readings by noting the difference between
each successive reading.
Always refer to the
specification for voltage drop information.
If the voltage drop specification is not available,
refer to the following list to determine the circuit's
maximum allowable voltage drop. Typical maximum
allowable voltage drop values for 12 Volt systems are
as follows:
Battery cable length up to 3 feet
Battery cable length over 3 feet
Magnetic switches
Solenoid switches
Mechanical switches
Battery cable connectors
Connections
NOTE: Do not use the allowable voltage drop values listed
above on circuits that use Aluminum cables.
Maximum voltage drop, normally should not be more
than 0.1V per wire, Ground, connection, switch or
solenoid. Thus, with the negative test probe connected
to the negative battery post and the positive test
probe connected to the starter drive housing frame,
total voltage drop should not exceed 0.4 Volts.
If the voltage drop reading is within the allowable
maximum voltage drop specification, the circuits
resistance is acceptable.
