NCV (Non-Contact Voltage) Testing
：
Caution
•
The feature can be used before locating, isolating,
cable mapping to identify if the tested cable is with
AC voltage. It can not only help to ensure the safety
of user and avoid possible electric shock or personal
injury, but also protect the product from being
damaged by AC power.
1.
Per Figure 11, turn the switch to “NCV”, the function is
started when the power indication is on.
2.
When doing the NCV testing, place the probe of MT-7028
receiver to the tested cable, the NCV indicator twinkled fast
and the buzzer sounded it means the tested objective has
AC 90~1000V. If the indicator did not come on and no
buzzer sounded, it means the tested objective has AC
power less than 90V or there is no AC power on it.
