Electric Field EF-Detection, Non-Contact Voltage
With Auto displayed on the LCD, press NCV button to enter the NCV function. The meter
displays EF. Signal strength is indicated as a series of bar graph segments on the display
and variable beep tones. See the specifications later in this manual for a complete
description of the bar graph indicators.
An antenna is located at the top right corner of the Conductor, which detects electric field
surrounding current-carrying conductors. It is ideal for tracing live wiring connections,
locating wiring breakage and to distinguish between live or earth connections.
* Probe-Contact EF-Detection
For more precise indication of live wires, such as distinguishing between live and ground
sockets, use the V ac manual function selection for direct contact voltage measurements.

Using Save and Read Features
1. Under any measurement mode, press SAVE button to enter save mode with beep
tone to indicate saving record is in process (number of records saved).
2. During measurement or AUTO mode, press READ button to exit the current
measurement mode or AUTO mode and to display the last number of saved reading.
Each presses to view the next saved reading, it is in first save last out bases. During
READ mode, press RESET button to exit.
