Product Description:
Varistor tester is an intelligent testing instrument specially designed for varistor sorting equipment. It is mainly used for measuring voltage limiting volt-ampere characteristic devices (varistor, zinc oxide arrester, voltage regulator, etc.)
The pressure sensitive voltage (UN) (or DC reference voltage), nonlinear index a and leakage current (IL) were measured. The design of the instrument conforms to the technical standards GB/T10193,GJB1782. It can also be used as a general direct current
Voltage source, current source is used, so it is a multifunctional, multi-purpose laboratory instrument. The instrument has high precision, fast speed, easy operation, visual disy, and all parameters are automatically measured and processed by the instrument. The instrument is pressure-sensitive
Resistance for two-way measurement, so that the quality of the product is more reliable
The instrument has two trigger modes: single and continuous. No trigger signal is needed for continuous time, and trigger measurement can only be carried out by trigger signal or trigger key on the panel for single time, and the sorting result can be output through PLC interface only for single test
The output voltage of the instrument can be set arbitrarily. If the appropriate output voltage is selected, the contact arc can be effectively eliminated during the test. Instrument panel with a key operation output voltage on and off function to prevent electric shock
This instrument is used for measuring and sorting U0.1mA voltage and leakage current of varistor (including SMDS and silver and lead products). Where U0.1mA and nonlinear index can be selected through the panel disy; There are two ways to measure leakage current:
Constant voltage measurement and U0.1mA XX.Xpercent voltage measurement, can be selected through the panel, constant voltage can be set arbitrarily,XX.Xpercent voltage can be set arbitrarily between 00.0Xpercent and 99.9percent; Or select by knob: Automatic,75percent,83percent constant voltage (adjusted by potentiometer).
Unidirectional or bidirectional measurement: fixed range and automatic range measurement of current and voltage can be selected respectively; Automatic sorting and filing instructions, optional sorting machine interface. Bidirectional measurement of 6 measurement data, through 6 groups of 4 green LED digital tube disy
The measurement results.
