Function Description:
The multimeter supports a variety of basic measurement functions, including:
- DC Voltage (DCV): Measures DC voltage across multiple ranges from 50.000 mV to 1000.0 V, with resolutions as fine as 0.001 mV.
- AC Voltage (ACV): Measures True RMS AC voltage from 500 mV to 750 V across different frequency ranges (20 Hz - 1 kHz).
- DC Current (DCI): Measures DC current from 500 uA to 10 A, with resolutions down to 0.01 uA.
- AC Current (ACI): Measures True RMS AC current from 500 uA to 10 A across different frequency ranges.
- Resistance (2-wire and 4-wire): Measures resistance from 500 Ω to 50 MΩ, with resolutions as fine as 0.01 Ω. The 4-wire resistance measurement offers enhanced accuracy, especially for small resistances, by minimizing the impact of test lead resistance.
- Continuity Test: Checks for continuity with a configurable threshold from 1 Ω to 1000 Ω (default 50 Ω). It provides an audible beeper when continuity is detected below the threshold.
- Diode Test: Measures the forward voltage drop of diodes, with a range of 0 to 3 V. It also includes a beeper function for indicating a forward bias below 0.7 V.
- Capacitance: Measures capacitance from 50 nF to 50 mF, with resolutions down to 0.001 nF.
- Frequency/Period: Measures frequency from 10.000 Hz to 60 MHz and the corresponding period.
- Temperature: Measures temperature using K-type thermocouples or PT100 sensors, with display units in Celsius (°C) or Fahrenheit (°F).

Usage Features:
- Auto and Manual Ranging: The multimeter automatically selects the appropriate range for measurements, or users can manually set the range for higher precision. An "overload" message is displayed if the input signal exceeds the current range.
- User Interface: Intuitive front panel with menu selection keys, operation keys (Save, Record, Run/Stop, Math, Utility, Port), and dedicated measurement function keys (V, A, Ω, continuity, diode, capacitance, frequency, temperature).
- Dual Display: Allows simultaneous viewing of readings from two different measurement functions. The primary and secondary functions can be configured, and the display can be switched between them.
- Data Hold: Freezes the current reading on the display, useful for recording stable values.
- Math Functions: Includes Max/Min/Average, dB, and dBm calculations.
- Max/Min/Average: Calculates the maximum, minimum, and average values over a measurement period.
- dB/dBm: Scales measurements relative to a reference value. dBm represents absolute power relative to 1 mW, calculated as
10 x log10 (reading² / reference resistance / 1 mW). dB represents the relative value of dBm. Reference resistance can be selected from a range of values (e.g., 50 Ω, 600 Ω).
- Relative Value (REL): Subtracts a pre-specified reference value from the actual measurement result, displaying the difference. This is useful for nulling out lead resistance in resistance measurements or comparing against a known standard.
- Data Record Function:
- Manual Record: Saves current readings to internal storage when the Save key is pressed. Up to 1000 points can be stored.
- Auto Record: Automatically records readings at a specified interval (15 ms to 9999.999 s) for a set number of points (up to 1000).
- Port Configuration: Allows setting serial port parameters like baud rate (2400 to 115200), parity (None, Odd, Even), and stop bits (1, 2).
- Utility Menu: Provides access to system settings such as language selection, backlight brightness adjustment, clock settings (date and time), and the option to restore factory defaults.
- Safety Information: Comprehensive safety guidelines including terms and symbols (Warning, Caution, Danger), general safety requirements (proper power cord, grounding, terminal limits, fuse usage, ventilation), and measurement categories (CAT I, CAT II).
Maintenance Features:
- General Care and Cleaning: Instructions for proper storage (avoid direct sunlight) and cleaning (use a wet soft cloth, avoid corrosive agents). Emphasizes disconnecting power and test leads before cleaning.
- Line Fuse Replacement: Detailed steps for replacing the line fuse located on the rear panel. Users are instructed to use the correct fuse type (250 V, F1AL for 90-240 V AC) to prevent damage or injury.
- Troubleshooting: Provides guidance for common issues such as no display (check power, fuse, restart) and current input not changing (check test lead connection, current terminal fuse, DCI/ACI function).
- Accessories: Includes a power cord, test leads, crocodile clips, a quick guide, and a spare fuse.
The MP730424 is designed for reliability and ease of use, making it suitable for a wide range of applications from basic electrical checks to more complex diagnostic tasks in various environments.
