单独一个阶段便携式标准Mter

Features With 3.5 inch 320×240 dot TFT color screen Wide voltage supply range: 50V 420V Wide current testing range: CCT test 500:1 dynamic range Connection with current clamp: standard 100A. From 5A to 500A current as option. Two ways for power supply: external AC power supply or test lead power supplyFunctions Measuring mode: gives the parameters of the line under test: voltage, current, phase angle active power, reactive power, apparent power power factor frequency Waveform: show the wave form of voltage and current Harmonics: make a graphic and numeric analysis of the THD. (2nd 51st) Meters test: Performs the test to the meters. The data field configurable in this function is the serial number, the meter type, the constant, the divisor factor (for HF), the type of test and cycles. CT ratio test: get CT ratio by synchronously testing primary and secondary current of CT Energy accumulating: accumulate active and reactive energy in a setting time, used for meter's dial test Test data storage: can store 1000 data groups. Data include meter type, serial number, constant, error, date, etc Download the testing program: can download 1000pcs testing planning to the equipment, convenient for local useTechnical Specification Accuracy Current clamp: 0.3% (active), 0.5%(reactive) Test voltage range 10V-300V Test current range 5A, 100A, 500A, 1000A, 2000A (current clamp) Phase measurement 0°-360° Frequency measurement 45Hz-65Hz Harmonic measurement 2nd -51st Power supply 50V-420V Power consumption <3W Dimension(W×H×D) 190mm×140mm×50mm Weight 0.7kg
