Use well-charged batteries in the tester.
Be sure to set the tester to the correct testing range.
Using the tester
Incorrectly connecting the (+) and @ probes may cause the inside of the tester to burnout.
If the voltage and current are not known, make measurements using the highest range.
When measuring the resistance with the multi-circuit tester (1), ∞ will be shown as 10.00 MΩ and "1" flashes in the display.
Check that no voltage is applied before making the measurement. If voltage is applied the tester may be damaged.
After using the tester, turn the power off.

Notes:
- When connecting the multi-circuit tester, use the needle pointed probe to the back side of the lead wire coupler and connect the probes of tester to them.
- Use the needle pointed probe to prevent the rubber of the waterproof coupler from damage.
