MN26

User’s Manual MiniTecTM Series Model MN26 (Model MN26T includes temperature probe) Mini Autoranging MultiMeter Introduction Congratulations on your purchase of Extech’s MN26 Autoranging Multimeter. This meter measures AC/DC Voltage, AC/DC Current, Resistance, Capacitance, Frequency, Duty Cycle, Temperature, Diode Test and Continuity. Proper use and care of this meter will provide many years of reliable service. Safety International Safety Symbols This symbol, adjacent to another symbol or terminal, indicates the user must refer to the manual for further information. This symbol, adjacent to a terminal, indicates that, under normal use, hazardous voltages may be present Double insulation Safety Precautions 1. Improper use of this meter can cause damage, shock, injury or death. Read and understand this user manual before operating the meter. 2. Make sure any covers or battery doors are properly closed and secured. 3. Always remove the test leads before replacing the battery or fuses. 4. Inspect the condition of the test leads and the meter itself for any damage before operating the meter. Repair any damage before use. 5. Do not exceed the maximum rated input limits. 6. Use great care when making measurements if the voltages are greater than 25VAC rms or 35VDC. These voltages are considered a shock hazard. 7. Always discharge capacitors and remove power from the device under test before performing Capacitance, Diode, Resistance or Continuity tests. 8. Remove the battery from the meter if the meter is to be stored for long periods. 9. To avoid electric shock, do not measure AC current on any circuit whose voltage exceeds 250V AC. 10. Voltage checks on electrical outlets can be difficult and misleading because of the uncertainty of connection to the electrical contacts. Other means should be used to ensure that the terminals are not "live".
