Page 14: Operation
6. Operation The transmitter has 3 different modes: ● Test mode: When the power is on, the transmitter is on the test mode. It can measure the AC or DC voltage of cable. When the user presses the TEST/STOP button, the transmitter will send a high frequency transmission signal down the cable. - Page 15 The receiver has 3 different modes: ● Auto detection mode: When the power is on, the receiver is on the auto detection mode to detect the high frequency transmission signal with the highest sensitivity. The speaker in the receiver will generate a tone(550Hz ~ 1.6kHz) and the bar-graph on the LCD indicates the signal strength.
- Page 16 (a) Connect the "+" (red) terminal to a single conductor, and connect the "COM" (black) terminal to earth. If there are other conductors in the same piping, then they have to be earthed at the same time. In this case, the MW9520-R can detect the NG position. -14-...
- Page 17 (b) Locating and tracing lines and outlets: The circuit must not be live when it is detected, connect the "+" (red) terminal of MW9520-E to the phase and the other "COM" (black) terminal to the protection earth wire. If the cable supplied...
- Page 18 MW9520-R can trace the mains line and detect the power socket is locating on the same mains line or not. -16-...
- Page 19 In another method, connect the both terminals of MW9520-E to the two ends of a single line. In this case, the MW9520-R can find out NG position or trace the signal line in the wall or floor.
- Page 20 The pipe must not be earthed, and there is a relatively high resistance between itself and ground. (otherwise, the detection distance is very short) Connect "+" (red) terminal of MW9520-E to the pipe and "COM" (black) terminal of MW9520-E must be earthed. -18-...
- Page 21 (b) Tracing an underground circuit: The circuit to be measured must not be live. Connect the MW9520-E as show in the figure. The MW9520-E must be correctly earthed. Select the automatic mode of MW9520-R to find and trace the circuit.
- Page 22 (d) Non-contact voltage detection: The circuit must be connected to mains and live, and set the receiver to the U mode to detect. The AC signals detected by the receiver in the U mode indicated only whether the circuit is live or not. During the search for the ends of several supply lines, the lines must be connected separately, one by one.

7. Maintenance (1) Battery Replacement: When the " " symbol appears and flashes on the LCD, change new batteries as follows: ● Disconnect the test leads from the transmitter and turn off the power of the transmitter. Unscrew the battery cover and replace with new batteries(1.5V AAA ×... - Page 24 (2) Cleaning and storage: WARNING To avoid electrical shock or damage to the instrument, do not get water inside the case. Periodically wipe the case with a damp cloth and detergent. Do not use abrasives or solvents. If the is not to be used for more than 60 instrument days, please remove the batteries for storage.
