  • Page 3: Introduction

    Introduction INTRODUCTION Congratulations. have purchased precision instrument manufactured to the highest quality standards. This Digital Multimeter is a general-purpose instrument designed for use in general electronics, home electrical applications, and auto-motive electrical/electronic systems. This meter is designed to test or measure AC voltage, DC voltage, batteries, DC current, AC current, resistance, diodes and continuity.

  • Page 4: Safety Precautions/ Warnings

    Safety Precautions / Warnings SAFETY PRECAUTIONS/ WARNINGS Do not operate this multimeter before reading this manual in its entirety. The following guidelines must be followed to avoid accidents that can result in electric shock or personal injury. Pay close attention to WARNINGS stamped on the front and rear of the meter's case.
  • Page 5 Safety Precautions / Warnings Do not hold the instrument when taking measurements. Place the instrument on a clean, insulating surface prior to taking any measurement. Don't become part of the circuit. Think safety. Act safely. If working on a vehicle, take the following added precautions: Only work on vehicle in a well ventilated area.

    Preparation and Caution Before Use PREPARATION AND CAUTION BEFORE USE. WARNING Inspect the digital multimeter for damage to the case. Do not use if cracked, distorted, excessively dirty or any abnormal condition exists. Inspect the test leads for damage. Check for cracked insulation, broken or damaged probes, loose or bent probe pins.

  • Page 8: Testing Procedures

    Testing Procedures TESTING PROCEDURES A. AC/DC VOLTAGE MEASUREMENT WARNING To avoid possible electric shock, instrument damage and/or equipment damage, DO NOT attempt to measure voltages ABOVE 600V AC/DC or take measurements if the voltage is unknown. 600V AC/DC between the COM and V jacks is the maximum voltage that this instrument is designed to measure.

  • Page 9: Diode Test

    Testing Procedures Plug the RED test lead into the "Ω" jack of the multimeter; plug BLACK test lead into the "COM" jack. Set the meter’s Function/ Range Selector Switch to BLACK the "Ω" range function (see LEAD LEAD Controls Indicators, Item 3).

  • Page 10: Continuity Test

    Testing Procedures Place the RED test lead onto one side of the diode being tested and the BLACK test lead onto the other side. Read the results on the display. Reverse the test leads and again read the results on the display.
