Introduction 2 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.
3 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.

7 AC Sensing: True RMS on MP520 and MP530 Auto Power Off: After 17 minutes of inactivity with no input signal Safety: The MultiPro™ Series meters are intended for indoor use and protected, against the users, by double insulation per EN61010-1 and IEC61010-1 2nd Edition (2001) to CAT III 1000V & CAT IV 600V. The meter (all versions) also meets UL3111-1(1994)* and CSA C22.2 No. 1010-1-92* to CAT III 1000V. Terminals (to COM) ratings: V: CATEGORY III 1000 VOLTS AC & DC, AND CATEGORY IV* 600 VOLTS AC & DC.
Meter Description (MP530 Shown) 8 1. 5000 count Liquid Crystal display 2. Function push-buttons 3. Rotary function switch 4. 10A input jack 5. V/Hz/Ω/Cap/Temp input jack 6. COM input jack 7. mA/uA current input jack NOTE: RS-232 Optical interface is located on the top rear of the meter. Features Analog Bargraph display Visual indication of measurement in the tradition of an analog meter pointer. The bargraph consists of 52 discrete viewing segments.
9 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.
Operation 10 Measurement Considerations NOTICE: Read and understand all warning and caution statements listed in the safety section of this operation manual prior to using this meter. 1. Always move the rotary function switch to the OFF position when the meter is not in use. This meter has Auto Power OFF that automatically shuts the meter OFF if 17 minutes elapse without activity. 2. If "OL" appears on the display during a measurement, the measurement exceeds the range selected. Change to a higher range.
11 Resistance and Continuity Measurements 1. Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the V/Ω/CAP jack. 2. Set the function switch to the "Ω " position. 3. Press the SELECT key momentarily to select Continuity (if required). 4. Touch the test probe tips across the circuit or part under test. It is best to disconnect one side of the part under test so the rest of the circuit will not interfere with the resistance reading. 5.
12 Frequency Measurements 1. Connect and make the measurement required as described in the previous paragraphs. 2. Press the Hz key to select the Frequency (Hz) function. 3. Read the frequency on the display Notes on sensitivity: Input sensitivity varies automatically with function range selected. The mV function has the highest (300mV) and the 1000V range has the lowest (300V) sensitivity.
13 MAX/MIN (MP530 only) 1. Press the MAX/MIN key to activate the MAX/MIN recording mode. The display annunciators "MAX/MIN" will appear. The meter will beep every time a new maximum or minimum reading is sensed. Auto power off is disabled while in MAX/MIN mode. 2. Press the MAX/MIN key to cycle through the stored MAX (maximum), MIN (minimum) and MAX-MIN (maximum minus minimum) readings. 3. To exit MAX/MIN mode press and hold the MAX/MIN key for 2 seconds. Relative mode (MP530 only) 1.
RS-232 PC Interface 14 This instrument is equipped with an optically isolated interface port (located on the rear of the meter). An optional WindowsTM software (part no. SW800) and interface package is available for data acquisition applications. This optional kit is required to connect the meter to a PC. The software provides digital, analog, and graphical data displays. Refer to the README file in the interface kit for further details.
15 Battery Replacement Loosen the 2 screws from the battery access door of the case bottom. Lift the battery access door and thus the battery compartment up. Replace the battery. Re-fasten the screws. Battery: Standard 9V Alkaline (NEDA1604, JIS006P, IEC6F22) Fuse Replacement 1. Remove the four screws from the case bottom and stand using a Philips head screwdriver. 2. Lift the end of the case bottom nearest the input jacks until it unsnaps from the case top 3. Replace the battery or blown fuse(s) 4.
