"Impressive measurement ranges including 0 to 1000A for AC current"

  • Description

    Dilog DL6403 1000A True RMS Clamp Meter

    The Dilog DL6403 1000A True RMS Clamp Meter is a versatile clamp meter that can measure AC current (0.01 to 1000A), AC/DC voltage (0.1mV to 600V), resistance (0.1Ω to 40MΩ), capacitance (0.0001nF to 40mF), frequency (0.001kHz to 4kHz) and temperature (-40˚C to 1000˚C). The True RMS measurement function for AC values improves accuracy to within 3% for current and 2% for voltage whilst the resolution changes depending on the selected measurement range so the user always has a precise picture of circuit performance. Furthermore, continuity and diode testing are available for comprehensive inspections.

    In addition to its impressive measurement ranges and accuracy, the Dilog DL6403 also has several practical features for ease of use. Firstly, the bright, clear, 4000-count LCD screen means that results are clearly visible whilst the measurement rate of 2/sec ensures that the user gets real-time values on screen. Auto power-off helps save the battery. The device features both data hold and peak hold so the minimum and maximum value are saved and the user can freeze a reading on screen which is very useful when a measurement cannot be taken with the screen facing the operator. Data can be presented both digitally and in a bar-graph depending on the user's preference.

    The 30mm 'teardrop' clamp can fit into tight spaces and the device is rated as Cat III up to 600V as well as meeting all applicable safety standards. The Dilog DL6403 comes provided with a thermocouple and test leads as well as a soft carry case for easy transportation. Overall, the impressive measurement ranges over most electrical variables make it a great instrument for inspecting electrical appliances and circuits.
