WINAPEX 189D DMM | Digital Multimeter In Pakistan

The WINAPEX 189D is a digital multimeter that combines a traditional rotary dial with a "smart" automatic function, making it easy to use for both hobbyists and professionals. In addition, it offers a wide range of measurement capabilities, including True RMS, which ensures accurate readings of both AC and DC signals. Furthermore, its intuitive design allows users to switch seamlessly between measurement modes, while maintaining reliability and precision. Therefore, this multimeter is an ideal tool for electronics enthusiasts, technicians, and engineers who need both versatility and accuracy in their daily work.

Key features:

• Display: It features a high-brightness, adjustable color screen with a 6000-count resolution (or 5999 counts, depending on the source), ensuring clear and precise readings even in low-light conditions.
• Rotary dial: The multimeter uses a "smart" rotary dial that allows for both manual range selection and an "AUTO" mode. This makes it more convenient than devices with a purely manual dial or a more complicated interface.
• Measurement functions: The 189D can measure a comprehensive list of electrical parameters, including:
  • DC Voltage: Up to 1000V
  • AC Voltage: Up to 750V (True RMS)
  • DC/AC Current: Up to 20A
  • Resistance: Up to 100MΩ
  • Capacitance: Up to 60mF
  • Frequency: Up to 10MHz
  • Diode and Continuity: Includes a buzzer for quick continuity checks.
• Enhanced diode test: It provides a higher open-circuit voltage (approx. 4.2V) for diode tests than many traditional multimeters, which makes it easier to measure a variety of LEDs.
• Safety features: It includes overload protection and features for live/null wire identification.
• Added functionality:
  • NCV (Non-Contact Voltage): Allows for the detection of live voltage without direct contact.
  • Data Hold: Freezes the current reading on the screen for easy recording.
  • Flashlight: A built-in flashlight assists with working in dark areas.
• Design: The device is compact and lightweight, making it highly portable for on-the-go electrical troubleshooting. 

Considerations:

• Current measurement: While it can measure up to 20A, it can only sustain this measurement for 10 seconds, and this function uses a 20A/250V ceramic fuse for protection.
• NCV performance: One user review noted that the Non-Contact Voltage detection performance was inconsistent, working "sometimes it worked sometimes it didn't".
• No temperature probe: Unlike the 189C model, the 189D does not come with a thermocouple for temperature measurements.
