Q: What is the alarm voltage?
A:1.1 to 1.2 times the test voltage
Q:Unable to reach the rated test voltage?
A: Adjust the series/parallel configuration of the reactors, add compensation capacitors, shorten the high-voltage wiring (≤5 m; equalizing leads are preferred), and dry any damp test specimens. If these measures are ineffective, contact the manufacturer.
Q: What situations are not covered by the free warranty?
A: Unauthorized disassembly or modification, operation beyond rated voltage or current limits, improper use in damp or explosive environments, or damage caused by wiring errors or human error will require paid repairs.
