☆ Calibrating AC Sampling for Real Load (Standard Meter Method)

TD4500 Calibrator For AC Sampling Devices and Transmitters

3PH voltage measuring range: 6 V ~ 456 V; 3PH current measuring range: 0.1 A ~ 6 A.
Current measurement supports two methods: direct input measurement or clamp (optional) measurement.
Application 1 (direct current measurement): calibrate 1PH/3PH voltage source, current source, and power source of class 0.2 and below in the laboratory or on-site.
Application 2 (clamp current measurement): In the past, when testing on-site AC sampling devices, it was usually necessary to wait for power outages for maintenance to disconnect the circuit, connect the standard ammeter in series to the loop for detection, or remove the meter to be tested to the laboratory for detection using the standard source method. When using a clamp meter to detect current, the circuit does not need to be short-circuited. Just clamp the current line into the jaws to perform real-time measurement online. This makes on-site detection faster and more convenient, and can meet the requirements of daily inspection of instrument operation status.
Note: The clamp is an option. If necessary, it should be indicated in the order contract.
