IWK-MG300Multimeter with wireless data transmitter

User's Guide Wireless TRMS Multimeter and Insulation Tester Model MG300 2 MG300-EN V2.0 4/11 Introduction Congratulations on your purchase of the MG300 True RMS MultiMeter Insulation Resistance Tester. This meter measures AC/DC Voltage, AC/DC Current, Resistance, Capacitance, Frequency (electrical & electronic), Duty Cycle, Diode Test, Insulation Resistance, and Continuity plus Thermocouple Temperature. The MG300 can store and recall measurement data and features a waterproof, rugged design for heavy duty use. This meter can transmit data wirelessly when linked to a PC. 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. This WARNING symbol indicates a potentially hazardous situation, which if not avoided, could result in death or serious injury. This CAUTION symbol indicates a potentially hazardous situation, which if not avoided, may result damage to the product. 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 (in this case) 1000 VAC or VDC. 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. PER IEC1010 OVERVOLTAGE INSTALLATION CATEGORY OVERVOLTAGE CATEGORY I Equipment of OVERVOLTAGE CATEGORY I is equipment for connection to circuits in which measures are taken to limit the transient overvoltages to an appropriate low level. Note – Examples include protected electronic circuits. OVERVOLTAGE CATEGORY II Equipment of OVERVOLTAGE CATEGORY II is energy-consuming equipment to be supplied from the fixed installation. Note – Examples include household, office, and laboratory appliances. OVERVOLTAGE CATEGORY III Equipment of OVERVOLTAGE CATEGORY III is equipment in fixed installations. Note – Examples include switches in the fixed installation and some equipment for industrial use with permanent connection to the fixed installation. OVERVOLTAGE CATEGORY IV Equipment of OVERVOLTAGE CATEGORY IV is for use at the origin of the installation. Note – Examples include electricity meters and primary over-current protection equipment WARNING CAUTION MAX 1000V 3 MG300-EN V2.0 4/11 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 Maximum Input V DC or V AC 1000VDC/AC rms mA AC/DC 500mA 1000V fast acting fuse A AC/DC 10A 1000V fast acting fuse (20A for 30 seconds max every 15 minutes) Frequency, Resistance, Capacitance, Duty Cycle, Diode Test, Continuity 1000VDC/AC rms Temperature 1000VDC/AC rms Surge Protection: 8kV peak per IEC 61010 2. USE EXTREME CAUTION when working with high voltages. 3. DO NOT measure voltage if the voltage on the "COM" input jack exceeds 1000V above earth ground. 4. 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. 5. ALWAYS discharge filter capacitors in power supplies and disconnect the power when making resistance or diode tests. 6. ALWAYS turn off the power and disconnect the test leads before opening the covers to replace the fuse or batteries. 7. NEVER operate the meter unless the back cover and the battery and fuse covers are in place and fastened securely. 8. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. 4 MG300-EN V2.0 4/11 Controls and Jacks 1. 40,000 count LCD display 2.

High-voltage circuits, both AC and DC, are very dangerous and should be measured with great care. 1. ALWAYS turn the function switch to the OFF position when the meter is not in use. 2. If “OL” appears in the display during a measurement, the value exceeds the range you have selected. Change to a higher range. 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 VDC 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. To…
