Introduction
Congratulations on your purchase of Extech model MP510, MP520, or MP530 digital multimeter. Properly used, this meter will provide many years of reliable service.
MultiPro™ Meters measure AC/DC Voltage, AC/DC Current, Resistance, Frequency, Capacitance, Diode, and Continuity. The MultiPro™ also offers RS-232 PC Interface data acquisition capabilities as an option. Models MP520 and MP530 are True RMS AC sensing. In addition, the MP530 offers Temperature, Relative, Peak capture and MIN/MAX functions.

Safety Precautions
1.Improper use of this meter can cause damage, shock, injury or death. Read and understand this users 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 or replace 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 for3 long periods.
9.To avoid electric shock, do not measure AC current on any circuit whose voltage exceeds 500V 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".
11.The product is intended only for indoor use
12.If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
13.Pollution degree: 2
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
