Analog Multimeter, Hi Sensitivity FET for Measuring Low Capacitance

Sanwa EM7000: High-Sensitivity Analog Multimeter with FET Technology

The Sanwa EM7000 is an advanced FET (Field-Effect Transistor) electronic analog multimeter designed for precise measurements, particularly in low-power circuits and those requiring high sensitivity. Its robust design and comprehensive features make it an indispensable tool for hobbyists, technicians, and engineers alike.

Key Features and Benefits:

• FET Technology for High Sensitivity: Utilizes FET technology, delivering exceptionally high input impedance. This is crucial for accurately measuring voltages in high-resistance circuits without loading the circuit, ensuring reliable readings, especially for lower capacitance values.
• Zero-Deflection Scale (NULL Function): Equipped with a zero-center meter for both DC Voltage and DC Current measurements, the NULL function allows for convenient relative measurements, quickly identifying deviations from a set reference point.
• Wide Measurement Capabilities: Offers extensive ranges for various parameters:
  • DC Voltage (DCV): From 0.3V up to 1000V (with input resistance from 2.5 to 12MΩ), including a ±DCV range for polarity-sensitive measurements.
  • AC Voltage (ACV): Measures RMS values (50/60Hz) from 3V up to 750V (with input resistance from approx. 800KΩ to 10MΩ).
  • Peak-to-Peak (Vp-p) Measurements: Capable of measuring peak-to-peak values of AC waveforms (sine, square, triangular waves with >20% duty cycle), providing valuable insights into signal characteristics.
  • DC Current (DCA): Ranges from 0.12µA up to 6A, ideal for a wide array of current analyses, including a ±DCA range for directional current flow.
  • AC Current (ACA): Measures up to 6A.
  • Resistance: Features an exceptionally wide ohm range, from 0.2Ω up to 200MΩ, allowing for thorough circuit diagnostics and component testing.
• Exceptional Accuracy: Maintains an impressive accuracy of ±3.0% of full scale for most measurements, ensuring dependable results.
• Extended Frequency Response: The AC low voltage ranges (3V and 12V) boast an excellent frequency characteristic of 40Hz to 1MHz for sine wave AC signals, making it suitable for a variety of audio and RF applications.
• Durable and Reliable: Engineered for longevity, the EM7000 is built to withstand demanding environments. It includes built-in fuses for enhanced safety during operation.
• Certified Quality: Each EM7000 comes professionally calibrated by Sanwa with a certificate of calibration, guaranteeing its precision and adherence to international standards.
