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

Features

Analog Bargraph display

Visual indication of measurement in the tradition of an analog meter

pointer. The bargraph consists of 52 discrete viewing segments. The

bargraph is useful for detecting faulty contacts, identifying

potentiometer gradations, and viewing signal spikes.

True RMS vs. Average Sensing (AC Measurements)

True RMS meters can accurately measure non-sinusoidal waveforms,

as well as distorted sine waves that contain harmonics. Average

Sensing is a fast, accurate and cost effective method of measuring

pure sine wave signals. However, non-sinusoidal waveforms cannot

accurately be measured using Average-sensing techniques.

NOTE: The MP510 is average sensing; the MP520 and MP530 are

True RMS.

Backlit display

The MultiPro™ series multimeters are equipped with a backlight for

viewing the LCD display in poorly lit areas.

Data Hold

The HOLD function freezes the reading on the display for later

viewing.

Manual and Automatic Ranging

The MultiPro™ series multimeters are Autoranging, with manual

override.

Smart Power Auto Power Off

Smart Power shuts the meter down automatically after approximately

17 minutes of inactivity.

Audible Beeper

To disable the audible meter tones, press and hold the Hz key while

powering the meter.

Automatic Test Lead Resistance Compensation

Automatically compensates for the resistance of the test leads, as well

as the internal protection circuitry automatically, ensuring greater

accuracy of low resistance measurements.

MAX/MIN mode (MP530 only)

MAX/MIN mode stores the minimum and maximum readings in

memory for later viewing.

Relative mode (MP530 only)

Relative mode allows the meter to display the difference between the

actual measurement and a stored reference value.

Zoom mode analog pointer (MP530 only)

The Zoom mode magnifies the regular analog bar graph resolution (up

to 5 times) to show small signal changes

PeakCcapture mode (MP530 only)

PeakC captures voltage or current signal that have durations as short

as 5ms. This mode is available in DCV, ACV, DCA, & ACA functions.
