The scope of application of the surge peak meter is the NA23 surge peak voltage meter, which is used to measure and store the peak values of surge voltage, surge current, and other single pulse peaks. An internal computing unit can directly display the peak value of the high-voltage side of the voltage divider in KV units. The display range is from 0.1kV to 16000KV, and this device is specifically designed for use in high-voltage laboratories. Special wiring, shielding, filtering, and overvoltage protection circuits are used to highly attenuate electromagnetic interference.

Measurement range of impact peak meter

By measuring the cable, the device is connected to the low voltage arm or high current shunt of the impulse voltage divider (anode or capacitor type device). For measuring voltage dividers (splitters), the surge peak voltmeter will introduce a 2MQ39pf load. If necessary, such as in the case of a resistive impulse divider, a matching resistor of 75Q (or 500) can be added to one of the two input terminals of the meter. The maximum peak value of the pulse voltage allowed for input by this device is 1600V. The measured value is displayed directly as a 5-digit number in kV. The unique feature of this device compared to commonly used impulse peak meters is that the measurement voltage range does not require manual switching, but is automatically switched by the device. The positive and negative polarities are automatically displayed on the screen,

The performance characteristics of the NA23 peak voltage meter are that it uses an industrial grade color touch display panel, and the operating interface has been improved to display in both Chinese and English (switchable) for user use; The measurement results can display waveform positive and negative peak values, or display positive peak values separately or negative peak values separately. When displaying positive and negative peak values separately, the font should be large for easy reading. The magnification can be set, and the peak voltage or current can be read directly. When the reading is greater than 999, the decimal point will be automatically adjusted in KA or KV units. The maximum sampling rate is 40MSPS, and a 12 bit A/D converter is used for high measurement accuracy.

This instrument uses multiple anti-interference measures, and its performance is stable and accurate in strong high-voltage electromagnetic environments. Screen high-performance devices to ensure long-term stability and precision of the instrument, and have RS232 interface that can communicate with computers or connect to micro printers. The instrument can automatically identify whether the component is broken or damaged, and if it is broken, it can output a switch signal.
