Introduction The DM5B digital multimeter is a pocket sized, hand held, battery operated, voltage, current and continuity measurement instrument. It provides the accuracy and numerous functions typically found in full sized multimeters. Features include • 750 Volts AC & DC • 5 Amps AC & DC • Continuity • Resistance to 30 • Megohms • Autoranging • Analog bar-graph • Data hold • Fuse protected current ranges Safety Notes Before using this meter, read all safety information carefully.
Operating Instructions V: Volts Ω: Ohms : Resistor (schematic symbol) : Continuity mode (4.1 kilohertz tone) : Diode (schematic symbol) mA: Milliamps DC or AC 5A: Five Amp DC or AC Meter Lead Connections WARNING! Grip leads behind finger guards when making measurements. The meter leads will be connected in this manner regardless of the measurement: Connect the black test lead to the terminal marked “COM” and the red test lead to the terminal marked “V/mA/A/Ω”.
To measure current, you must break the circuit under test (cut a wire for example) and make the meter part of the circuit. This creates two connection points. On one side is the power source and the other is the load. If DC current is being measured, a minus sign will be displayed when current is flowing opposite to the connection polarity. 1. Ensure power is off to the circuit to be tested. 2. Set the rotary switch to the mA or 5A position (depending on the maximum possible amperage you will be measuring).
