Figure 2 MT-7028 Receiver Diagram 

1. 

Probe

Used for cable tracing and NCV detection.

 

2. 

LED illumination

Used for dark working environment.

 

3. 

Power ON/OFF indicator

The indicator will be lighted up 

when the switch at LED or NCV position and the receiver 
started the functions. When the switch at OFF position, 
the indicator will be light up when pushing “

” button for 

cable tracing.

 

4. 

NCV indicator

When the probe closes to the tested 

object to detect the voltage, the indicator will light up if the 
object carried AC90~1000V. If the indicator did not light up, 
there is no voltage detected from the object or the AC 
voltage is less than 90V. 

 

5. 

Signal status indicator

When doing cable mapping by 

probe, if the indication LEDs (1~8) more light up, the 
signal is stronger.

6. 

Volume control

By adjusting the volume from high to low 

to adjust the sensitivity of probe. Move the position of 
receiver from 30 cm to 10cm to find out the cable you are 
tracing.
