Page 4: Introduction
1. INTRODUCTION The MT878 is an auto ranging multimeter integrated with a Stud and Metal detector as well a NCV detector, being a useful tool for professionals across diverse industries. Quickly locates studs behind walls, pinpoint metal objects buried in surfaces, and safely detect AC wires with confidence. The DMM function makes it easy to measure AC Volts, DC Volts, AC and DC Current, Resistance, Temperature, Capacitance, Continuity and Diode Test. -
Page 5: International Safety Symbols
2.3. International Safety Symbols This symbol adjacent to another symbol, terminal or operating device indicates that the operator must refer to an explanation in the Operating Instructions to avoid personal injury or damage to the meter. This symbol adjacent to one or more terminals identifies them as being associated with ranges that may, in normal use, be subjected to particularly hazardous voltages. -
Page 6: Maintenance
Test Leads WARNING: Operation is limited to CAT II applications when the insulated tips are removed from one or both test probes. Refer to Input Limits section in this manual for maximum voltage ratings. 2.5. Maintenance This multifunction meter is designed to provide years of dependable service, if the following instructions are performed: 1. -

Note: 1-LED display, 3-Functian select button, 4-0N/OFF button, 13- Calibration/Stud Range button and 14/15/16 only use in Stud/Metal/NCV detection, others for Multimeter. 3.2. Symbols Used on LED Display (STUD/METAL Finder) Metal detection Select range 1: 0 to ½" 10 to 13mm) Stud detection Select range 2: 0 to 1"... -
Page 8: Stud/Metal Finder Operation
4. STUD/METAL FINDER OPERATION 4.1. Operation Tips • Hold the tool straight up and down, parallel to the studs, and do not rotate the tool. Ÿ During the stud detection, the hand holding the meter cannot leave the meter surface or change its position on the meter. If your hand leaves the surface of the meter during the scanning, the test signal will be affected, the stud detection symbol will flash, and the meter will be reinitialized. -

• Range/CAL button: The calibration function only valid in the Metal/Stud detection mode, and the range setting is only valid in the stud detection mode. 4.3. Metal Detection • Metal detection has interactive calibration to adjust its sensitivity to metal, which can be used to find the precise location of metal objects in walls, floors, and ceilings. -

scanning area, repeat step B. This procedure can be repeated multiple times to narrow the field even further. Note: If the meter is directly placed on the metal surface for calibration, it will result in an error display, the metal symbol is always on, and other symbols flash, the beeper will beep. -
Page 11: Ncv Detection
Note: If the meter is directly placed on the metal or other material surface for calibration, it will result in an error display, the stud symbol is always on, and other symbols flash, the beeper will beep. Move the meter to another place and re-calibrate. -
