NCV (Non-Contact Voltage) TEST
Caution
•
The feature can be used before locating, isolating, cable mapping to
identify if the tested cable has AC voltage present. It cannot 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 12, turn the switch to “NCV”, the function is started when the
power indication is on.
2. When doing the NCV testing by approaching the probe of MT-7071
receiver to the tested cable, the NCV indicator twinkled fast and the
buzzer sounded means the tested objective has AC 90~1000V. If the
indicator did not go on and no buzzer is sounded, it means the tested
objective has AC power less than 90V or there is no AC power on it.
