Varistor tester FC-2G

for lightning arrestorstubefor varistor

The FC-2G lightning protection components tester is designed to measure DC parameters of zinc oxide arresters (varistors), cermet two- and three-electrode discharge tubes and other surge-protection components. It also functions as a regulated power supply and a constant-current source for test setups.

Key features:

• Applicable to DC parameter testing of ZnO arresters (voltage-dependent resistors), cermet 2-/3-electrode discharge tubes, vacuum lightning tubes and similar overvoltage protection components.
• Operates as a regulated power supply and as a constant-current source.
• High-voltage (HV) short-circuit protection and over-current protection; HV preset and range adjustment functions; HV self-discharge time < 0.5 s.
• Built-in self-calibration function.
• LCD display providing precise readings and reliable operation.
• Pre-set measurement range with audible alarm when measured value exceeds the set range.
• Continuous measurement mode for batch testing and production control.
• Simple front-panel operation; lightweight and portable (dimensions and weight below).
