3) PRODUCT DESCRIPTION Panel Illustration 1) 5000 count LCD display 2) Push-buttons for special functions & features 3) Selector to turn the Power On or Off and Select a function 4) Input Jack for 10A (20A for 30sec) current function 5) Input Jack for all functions EXCEPT current (μA, mA, A) functions... - Page 5 Analog bar-graph The analog bar graph provides a visual indication of measurement like a traditional analog meter needle. It is excellent for detecting faulty contacts, identifying potentiometer clicks, and indicating signal spikes during adjustments. Average sensing RMS calibrated RMS (Root-Mean-Square) is the term used to describe the effective or equivalent DC value of an AC signal.

Page 6: Operation
CMRR (Common Mode Rejection Ratio) Common mode voltage is voltage present on both the COM and VOLTAGE input terminals of a DMM, with respect to ground. CMRR is the DMM's ability to reject common mode voltage effect that can cause digit rolling or offset in voltage measurements. -
Page 7: Forward Bias
Capacitance, Diode test function Default at . Press SELECT button momentarily to select Diode test function. CAUTION Discharge capacitors before making any measurement. Large value capacitors should be discharged through an appropriate resistance load. Diode Diode Reverse Bias Forward Bias Normal forward voltage drop (forward biased) for a good silicon diode is between 0.400V to 0.900V. - Page 8 Temperature function (Model MP530 only) Press SELECT button momentarily to toggle between °C and °F readings, and the new setting will be saved automatically in the non-volatile memory as power up default. K-temp K-temp Note: Be sure to insert the banana plug K-type temperature bead probe with correct polarities.

- Page 10 μA, mA, and A Current functions Default at DC. Press SELECT button momentarily to select AC. *Note: When measuring a 3-phase system, special attention should be taken to the phase-to-phase voltage which is significantly higher than the phase-to-earth voltage. To avoid exceeding the voltage rating of the protection fuse(s) accidentally, always consider the phase-to-phase voltage as the working voltage for the protection fuse(s).
- Page 11 50ms MAX/MIN at fast 20/s measurement mode (Model MP530 only) Press the MAX/MIN button momentarily to activate MAX/MIN recording mode. The LCD annunciators “MAX MIN” turn on, and the reading update rate will be increased to 20/second. The meter beeps when a new maximum or minimum reading is updated. Press the button momentarily to read throughout the Maximum (MAX), Minimum (MIN), and Maximum minus Minimum (MAX-MIN) readings.
- Page 12 Backlighted display Press the SELECT button for 1 second or more to turn on or off the display backlight function. The backlight will also be turned off automatically after 30 seconds to extend battery life. Hold The hold function freezes the display for later viewing. Press the HOLD button momentarily to activate or to exit the hold function Zoom 5x analog pointer (Model MP530 only)
- Page 13 Relative mode (Model MP530 only) Relative zero allows any reading to be stored as a reference value and all following reading to be reference to that value. Practically all displaying readings can be set as relative reference value including MAX/MIN feature readings. Press the button momentarily to activate and to exit relative zero mode.

Auto Power Off (APO) The Auto Power Off (APO) mode turns the meter off automatically to extend battery life after approximately 17 minutes of no activity. Activities are specified as: 1) Rotary switch or push button operations, and 2) Significant measuring readings of above 10% of range or non-OL Ω... - Page 15 Trouble Shooting If the instrument fails to operate, check battery, fuses, leads, etc., and replace as necessary. Double check operating procedure as described in this user’s manual If the instrument voltage-resistance input terminal is subjected to accidental high voltage transient the series fusible resistors will blow (become high impedance), like standard fuses, to protect the user and the instrument.
