Pin Configuration

Component Name: Original Mastech MS830L Digital Pocket Multimeter with Probes
Pinout Explanation:
The Original Mastech MS830L Digital Pocket Multimeter comes with a set of probes that connect to the multimeter's input terminals. These probes enable users to measure various electrical parameters such as voltage, current, resistance, and continuity. Here's a detailed explanation of the pins, one by one, along with their functions and how to connect them:
Probe Connectors:
The multimeter has three probe connectors: COM, VmA, and mAV.
1. COM (Common) Probe:
Pin Function: Ground/Reference Point
Color: Black
Description: The COM probe is the ground or reference point for the multimeter's measurements. It's used as a common connection for most measurements.
Connection: Connect the COM probe to the negative terminal of the circuit or device being measured.
2. VmA Probe:
Pin Function: Voltage/Resistance/Current Measurement
Color: Red
Description: The VmA probe is used for measuring voltage, resistance, and current. It's connected to the multimeter's positive input terminal.
Connection: Connect the VmA probe to the positive terminal of the circuit or device being measured.
3. mAV Probe:
Pin Function: Current Measurement (mA range)
Color: Red (with a yellow stripe)
Description: The mAV probe is used exclusively for measuring current in the milliampere range (mA). It's connected to the multimeter's positive input terminal.
Connection: Connect the mAV probe to the positive terminal of the circuit or device being measured, but only when measuring current in the mA range.
Connection Structure:
Here's a summary of the connection structure:
COM (Black) probe: Connect to the negative terminal of the circuit or device being measured.
VmA (Red) probe: Connect to the positive terminal of the circuit or device being measured for voltage, resistance, and current measurements.
mAV (Red with Yellow Stripe) probe: Connect to the positive terminal of the circuit or device being measured, but only for current measurements in the mA range.
Important Safety Notes:
Always ensure the multimeter is set to the correct measurement range and function before taking readings.
Never touch the probes to each other or to any metal objects while taking measurements.
Use the correct probe for the measurement type to avoid damage to the multimeter or the circuit being measured.
Follow proper safety precautions when working with electrical circuits, such as wearing protective gear and ensuring the circuit is de-energized when necessary.
