ENFORCER 12VDC 6-in-1 Battery Tester with Continuity
SECO-LARM U.S.A., Inc 3
Test #4: Load Test (12VDC Only)
1.
Using the alligator test leads, connect each clip to the power source being tested.
2.
Depending on the application, use the load selection switch to select a 0.5A or 1A load for testing.
3.
Press and hold the Load Test button for 6~10 seconds. The four LEDs (red, yellow, green and blue)
will show the strength of the voltage present under the load that has been selected.
4.
When the “Test Done” LED illuminates, release the Load Test button. The Load Test button should
not be held past this time. Wait about 30 seconds for the unit to cool before performing further tests.
Test #2: Voltage Test (DC Voltage Only)
1.
Using the alligator test leads, connect each clip to the output wires or terminals being tested.
2.
The four LEDs (red, yellow, green and blue) will display the voltage present as shown in the table
below. The power LED will turn on for voltage from 3~15.6 VDC and 21~30 VDC.
3.
The power LED will turn red for voltage from 3~15.6 VDC and blue for voltage from 21~30 VDC.
Note: Unit is intended for use with 12VDC. Power LED shows 24VDC for indication purposes only.
Test #3: Polarity Test (12VDC Only)
1.
Connect the test leads to the wires or terminals being tested.
2.
Connect the tester’s 2.1mm DC illuminated jack directly to the
2.1mm DC plug of any 12VDC power source.
3.
The illuminated connector will show the polarity of the power
present. Intensity of the LED is proportional to the voltage.

Test #5: Voltage Drop Test (12VDC Only)
1.
Set a load (0.5/1.0 A) similar to the device you will connect.
2.
Connect the tester to the DC power supply’s output terminal.
Read the tester voltage LEDs when the load is applied.
3.
Connect the tester to the device end of the power supply
cable. Read the tester voltage LEDs when the load is applied.
4.
The voltage drop is difference between the power source’s
voltage and the voltage reading at the end of the cable run.
