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 for

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

3

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
