Proper use and care of this meter will provide many years of reliable service. Please visit the Extech Instruments website (www.extech.com) to check for the latest version of this User Guide. Extech Instruments is an ISO-9001 certified company.
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.
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 AC/DC, Resistance, Diode Test, Continuity 600 VDC/AC rms μA or mA AC/DC 200mA fused A AC/DC 10A fused 2. USE EXTREME CAUTION when working with high voltages. 3.

Operating Instructions WARNING: Risk of electrocution. High-voltage circuits, both AC and DC, are extremely 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. AC/DC VOLTAGE MEASUREMENTS CAUTION: Do not measure DC voltages if a motor on the circuit is being switched ON or OFF.
RESISTANCE MEASUREMENTS WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any resistance measurements. Remove the batteries and unplug the line cords. 1. Rotate the function switch to the Ω 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 device under test. 4. Read the resistance in the display.
NON-CONTACT INFRARED TEMPERATURE MEASUREMENTS 1. Rotate the function switch to the IR position. The upper right four digit temperature display will switch on. 2. Press the MODE button to select °F or °C. 3. Aim the infrared sensor (top of meter) at the surface to be measured. 4. Press and Hold the IRT button to turn on the IR thermometer and laser pointer. The laser pointer identifies the surface spot to be measured and “SCAN” will flash in the display. 5. Read the temperature in the display. 6.
AUTORANGING/MANUAL RANGE SELECTION When the meter is first switched on, it automatically enters the AutoRanging mode. This automatically selects the best range for the measurements being made and is generally the best mode for most measurements. For measurement situations requiring that a range be manually selected, perform the following: 1. Press the RANGE button. The “AUTO” display indicator will turn off. 2. Press the RANGE key to step through the available ranges until the range desired is selected. 3.
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 the 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 followed: 1. KEEP THE METER DRY. If it gets wet, wipe it off. 2. USE AND STORE THE METER IN NORMAL TEMPERATURES.
