User's Guide Mini Digital Multimeter Model MN15A A Introduction Congratulations on your purchase of the Extech MN15A MultiMeter. The MN15A offers AC/DC Voltage, AC/DC Current, Resistance, Diode, and Continuity testing plus Type K thermocouple temperature measurements. Proper use and care of this meter will provide many years of reliable service. Safety 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. WARNING This WARNING symbol indicates a potentially hazardous situation, which if not avoided, could result in death or serious injury. CAUTION This CAUTION symbol indicates a potentially hazardous situation, which if not avoided, may result damage to the product. MAX 600V This symbol advises the user that the terminal(s) so marked must not be connected to a circuit point at which the voltage with respect to earth ground exceeds 600V. 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. For maximum safety, the meter and its test leads should not be handled when these terminals are energized. This symbol indicates that a device is protected throughout by double insulation or reinforced insulation. SAFETY INSTRUCTIONS This meter has been designed for safe use, but must be operated with caution. The rules listed below must be carefully followed for safe operation. 1. NEVER apply voltage or current to the meter that exceeds the specified maximum: Input Protection Limits Function 2. 3. 4. 5. 6. 7. 8. Maximum Input VDC or VAC 600VAC and VDC VDC or VAC 200mV range 200Vrms mA AC/DC 200mA 250V fast acting fuse A AC/DC 10A 250V fast acting fuse (for 30 seconds max. every 15 minutes.) Resistance, Continuity 250Vrms for 15 sec. max. USE EXTREME CAUTION when working with high voltages. DO NOT measure voltage if the voltage on the "COM" input jack exceeds 600V above earth ground. NEVER connect the meter leads across a voltage source while the function switch is in the current, resistance, or diode mode. Doing so can damage the meter. ALWAYS discharge filter capacitors in power supplies and disconnect the power when making resistance or diode tests. ALWAYS turn off power and disconnect test leads before opening the covers to replace the fuse or battery. NEVER operate the meter unless the back cover and the battery and fuse covers are in place and fastened securely. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. 2 MN15A-en-US_1.4 4/15 Controls and Jacks 1. LCD display 2.

High-voltage circuits, both AC and DC, are very dangerous and should be measured with great care. NOTE: On some low AC and DC voltage ranges, with the test leads not connected to a device, the display may show a random, changing reading. This is normal and is caused by the high-input sensitivity. The reading will stabilize and give a proper measurement when connected to a circuit. AC VOLTAGE MEASUREMENTS WARNING: Risk of Electrocution. The probe tips may not be long enough to contact the live parts inside some 240V outlets for appliances because the contacts are recessed deep in the outlets. As a result, the reading may show 0 volts when the outlet actually has voltage on it. Make sure the probe tips are touching the metal contacts inside the outlet before assuming that no voltage is present. CAUTION: Do not measure AC voltages if a motor on the circuit is being switched ON or OFF. Large voltage surges may occur that can damage the meter. 1. Set the function switch to the 600 VAC position. 2. Insert the black test lead banana plug into the negative COM jack. Insert red test lead banana plug into the positive V jack. 3. Touch the black test probe tip to the neutral side of the circuit. 4. Touch the red test probe tip to the “hot” side of circuit. 5. Read the voltage in the display. 6. If the reading is less than 200V, switch to the 200V range to improve resolution. DC VOLTAGE MEASUREMENTS CAUTION: Do not measure DC voltages if a motor on the circuit is being switched ON or OFF. Large voltage surges may occur that can damage the meter. 1. Set the function switch to the highest 600VDC position. 2. Insert the black test lead banana plug into the negative COM jack. Insert the red test lead banana plug into the positive V jack. 3. Touch the black test probe tip to the negative side of the circuit. Touch the red test probe tip to the positive side of the circuit. 4. Read the voltage in the display. 5. If the reading is less than the maximum of a lower range, switch to that range to improve resolution. 4 MN15A-en-US_1.4 4/15 DC CURRENT MEASUREMENTS CAUTION: Do not make current measurements at 10 Amps for longer than 30 seconds. Exceeding 30 seconds may cause damage to the meter and/or the test leads. 1. Insert the black test lead banana plug into the negative COM jack. 2. For current measurements up to 200mA, set the function switch to the 200mA position and insert the red test lead banana plug into the mA jack. 3. For current measurements up to 10A, set the function switch to the 10A position and insert the red test lead banana plug into the 10A jack. 4. Remove power from the circuit under test, then open up the circuit at the point where you wish to measure current. 5. Touch the black test probe tip to the negative side of the circuit. Touch the red test probe tip to the positive side of the circuit. 6. Apply power to the circuit. 7. Read the current in the display. 5 MN15A-en-US_1.4 4/15 RESISTANCE MEASUREMENTS WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any resistance measurements. 1. Set the function switch to the highest position. 2. Insert the black test lead banana plug into the negative COM jack. Insert the red test lead banana plug into the positive jack. 3. Touch the test probe tips across the circuit or part under test. 4. Read the resistance in the display. Move the function switch to successively lower ranges to obtain a higher resolution reading. CONTINUITY CHECK WARNING: To avoid electric shock, never measure continuity on circuits that have a voltage potential. 1. Set the function switch to the 2. Insert the black lead banana plug into the negative COM jack. Insert the red test lead banana plug into the positive jack. position. 3. Touch the test probe tips to the circuit or wire you wish to check. 4. If the resistance is less than approximately 100, the audible signal will sound. If the circuit is open, the display will indicate “1. ”. DIODE TEST 1. Set the function switch to the 2. Insert the black test lead banana plug into the negative COM jack Insert the red test lead banana plug into the positive jack. position. 3. Touch the test probes to the diode under test. 4. A typical diode will indicate approximately .400 to .500 volts for the forward test and “1. ” for the reverse test. 5. A shorted diode will indicate a low value in both the reverse and forward test directions. An open diode will indicate “1. ” in both test directions. 6 MN15A-en-US_1.4 4/15 BATTERY VOLTAGE TEST CAUTION: Do not measure batteries while they are installed in the devices they are powering. The batteries must be removed from installations before tests can be made. 1. Set the function switch to the 1.5V or 9V BAT switch position. Use the 1.5V position for ‘AAA’, ‘AA’, ‘C’, ‘D’, and other 1.5V batteries. Use the 9V position for square 9V transistor batteries. 2. Insert the black test lead banana plug into the negative COM jack. Insert the red test lead banana plug into the positive V jack. 3. Touch the black test probe tip to the negative side of the battery. Touch the red test probe tip to the positive side of the battery. 4. Read the voltage in the display. TEMPERATURE MEASUREMENTS 1. Set the function switch to the °F or °C position. 2. Insert the Temperature Probe into the COM and Temp jacks, making sure to observe the correct polarity. 3. Touch the Temperature Probe head to the part to be measured. Keep the probe touching the part under test until the reading stabilizes. 4. Read the temperature in the display. Note: The temperature probe is fitted with a type K mini connector. A mini connector to banana connector adaptor is supplied for connection to the input banana jacks. 7 MN15A-en-US_1.4 4/15 Maintenance WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the back cover or the battery or fuse covers. WARNING: To avoid electric shock, do not operate your meter until the battery and fuse covers are in place and fastened securely. This MultiMeter is designed to provide years of dependable service, if the following care instructions are performed: 1. 2. KEEP THE METER DRY. If it gets wet, wipe it off.
