Testing Procedure
Connect the red test lead to the “+” jack and the black test lead to the “-” jack.
1. Press the Power
button to switch the tester ON.
2. Use the V-RANGE or -RANGE buttons to select the desired Voltage or Resistance range.
3. Perform a REL Zero adjustment (see next section) each time the range is changed.
4. Connect the red test probe to the positive battery terminal, and the black test probe to the
negative battery terminal.
5. Read the battery’s internal resistance and the DC voltage directly on the meter’s display.
Note: When the measured DC voltage or battery internal resistance value is over range, “OL” is
displayed. When the AC test current faults “- - - -” will be displayed.
REL Adjust (ZERO)
The REL function zeros the selected range. The reading displayed when the REL button is pressed
will be taken as zero and will be used to ‘offset’ subsequent measurements.
1. Short the four (4) probe tips of the red and black test leads as shown in the accompanying
diagrams.
2. Press the REL button and the display will show the ‘R’ icon and the resistance and voltage
values will zero.
3. Connect the test leads to the battery to be tested.
4. The REL button must be pressed each time the range of the meter is changed, after the test
leads are swapped, or after switching between resistance and voltage tests.
