Tilswall FY8233X, User Manual

Note:

1. Even if there is no indication, the voltage may still exist. Do not 

rely on non-contact voltage detectors to determine whether there is 

voltage on the wires, the detection operation may be affected by 

the socket design, insulation thickness and different types, etc.

2. The interference sources of external environment (such as 

flashlight, motor, etc.) may trigger non-contact voltage detection by 

mistake.

1. Auto off: if the function key or range switch of meter is not in use 

for about 20 minutes. The beeper will sound beep~beep to indicate 

that the meter will enter sleep state soon before the meter is turned 

off; before entering the sleep state, the beeper will sound beep 

once then the meter enters the sleep state. Press any key or turn 

the range switch to OFF to restart the meter to wake up the meter.

Non-contact AC Voltage 

Measurement

Set the function range switch to the desired NCV range position, 

the screen displays ---, place the top of the meter close to the 

conductor. When the detected voltage is higher than 80V (RMS), 

the beeper will make a Di~Di alarm sound, and the alarm sound will 

change from slow to fast, the faster the closer to the conductor, the 

screen displays “--L” at the same time to represent LOW (low 

voltage), and “--H” to represent HI (high voltage).
