The Jaltest JT2003 is a digital multimeter designed for industrial applications. The device features a True RMS measurement function, guaranteeing accurate measurements of both sinusoidal and non-sinusoidal AC waveforms. The enclosure has an IP65 rating, meaning it is completely dust-tight and protected against water jets. Additionally, the multimeter has been tested for drop resistance up to 2 meters, supporting durability in demanding work environments. The instrument can perform measurements for voltage, current, resistance, capacitance, frequency, duty cycle, and continuity.
This multimeter is equipped with various specialized functions. The Low Pass Filter (LPF) function allows precise voltage and frequency measurements on variable frequency drives (VFDs). The LoZ low input impedance mode helps eliminate ghost voltages for more reliable measurements. A specific MOTOR TEST function is available to check the rotation direction of three-phase motors. Furthermore, the JT2003 features a peak detection of 250 µs for capturing transients, a 6000-count display with backlighting that automatically adjusts to ambient light, and the ability to measure both AC and DC components simultaneously.
Application and functionality:
The JT2003 is developed for diagnosis and maintenance in the automotive, industrial, and maritime sectors. The functions are specifically aimed at measuring electrical and electronic systems.
- True RMS measurement: Ensures accurate display of AC voltage and current under complex, non-linear loads.
- IP65 protection rating: The enclosure is fully sealed against dust and resistant to water, enabling use in harsh conditions.
- Drop resistance: Designed to withstand a 2-meter drop, enhancing robustness.
- Low pass filter (LPF): Filters high-frequency noise for stable measurements on variable frequency drives and other noisy electrical environments.
- LoZ voltage measurement: The low input impedance prevents false readings caused by ghost voltages induced by nearby conductors.
- Motor test: Simplifies the check of phase rotation in three-phase motors.
- Peak detection (Peak capture): Captures short voltage and current peaks with a response time of 250 microseconds.
- Automatic backlight: A built-in light sensor automatically adjusts the display brightness, improving readability and extending battery life.
