Mastech MS8217 Digital Multimeter - Quick Start Guide
This guide provides essential information for the safe and effective use of the Mastech MS8217 Digital Multimeter.
Safety Precautions
Special attention should be paid when using this test and measurement instrument, as improper usage may cause electric shock and damage the equipment.
- Use proper measurement category (CAT), voltage, and amperage rated probes, test leads, and adapters.
- Do not use or store the device around explosive gas, vapor, or under high temperature and humidity.
- When handling test probes and crocodile clips, keep fingers behind the physical guard.
- Examine test leads before use. If any part of the insulation is deteriorated, replace them with proper functional test leads.
- Connect the common test lead before the live test lead, and remove the live test lead before the common test lead.
- Before measuring current, ensure the instrument fuses are available and disconnect the power supply to the circuit being tested.
- Remove batteries if the device is not used for an extended period or is stored in temperatures above 45°C to prevent battery leakage damage.

Basic Measurement Operations
DC Voltage Measurement:
- Connect the black test lead to the COM terminal and the red test lead to the VΩ terminal.
- Select the DC voltage range (V=).
- Connect the test leads across the component or circuit to be measured.
- Read the voltage on the display.
AC Voltage Measurement:
- Connect the black test lead to the COM terminal and the red test lead to the VΩ terminal.
- Select the AC voltage range (V~).
- Connect the test leads across the component or circuit to be measured.
- Read the voltage on the display.
Current Measurement (DC/AC):
