and then select the appropriate range according to the
current.
• Connect the Meter to the circuit under test in series, and then
turn on the power supply of the circuit.
• After the reading stabilizes, record the reading from the LCD
screen.
• Turn the rotary switch to the OFF position to turn off the Meter.
AUTOMOTIVE PARASITIC BATTERY DRAIN:
• Check if the battery voltage and power generation are within
normal range. The battery voltage is generally around 12 7V
and the power generation is around 14V
• Turn off all electrical accessories inside and outside the car and
close the doors
• Remove the negative electrode of the battery. Set the
Multimeter to the maximum current level and connect the Meter
in series to the battery.
Connect the red test lead to the negative line and the black test
lead to the battery terminal.
Adjust the Meter, if necessary, to a lower range.
Wait for about 30 minutes; after all the modules of the vehicle
have entered the sleep state, read the accurate static discharge
current. The discharge current is generally 0.02A (20mA),
however, this can vary depending on the vehicle. Normally it
will not exceed 50mA.
• If the drain is larger than 50mA, begin checking fuses
individually for which circuit is carrying the excess load
If a removed fuse reduces the battery draw to below 50mA, it
can be determined that the corresponding circuit is drawing the
excess discharge.
