Detecting cables,electrical lines,water/gas supply pipelines buried in wall or earth. Detecting interruptions and short circuit in cables and electrical lines buried in wall or earth. Detecting fuses and assigning current circuits. Detecting interruptions and short-circults in floor heating. Detecting sockets and distribution sockets having accidentally been covered by plastering. The transmitter is integrated with the function of AC/DC voltmeter,which can measure 30 to 400V AC/DC voltage on a linear basis. The screen of the transmitter can display preset transmitting power,transmitted codes,its own battery energy,mains voltage detected,AC/DC status of mains voltage detected, and warning symbol for mains voltage. The Transmitter has the function of self-inspection to detect its own working status and to display it on the LCD screen for user's reference. The sensitivity of the receiver can be adjusted either manually or automatically. The receiver can sweep frequency automatically,both the transmitter and the receiver can work under mute mode Additional transmitters are available for expansion or to differentiate between multiple signals compactness,durability and portability When installing or replacing the battery, please be sure to pay attention to the correct polarity of the battery. If the battery polarity is reversed, damage to the device may occur. Notice: 1. This detector can measure when the object being measured is charged. To avoid electric shock and injury, please provide insulation protection in accordance with industrial safety regulations. 2. When working with a voltage greater than 120V (60V) DC or 50V (25V) eff AC, to prevent electric shock, be sure to comply with the safety regulations on high contact voltage and DIN VDE regulations. The values in parentheses apply to restricted areas such as medical settings, farms, etc.). Model Number: MS6818 Length of Test Leads: 95CM Voltage Measurement Ran
