【FAQ】

Q1: What is the maximum insulation resistance that the CA6541 can measure?
A1: The CA6541 can measure insulation resistance up to 4 TΩ using test voltages between 50 V and 1000 V DC.

Q2: Can this tester calculate PI and DAR automatically?
A2: Yes. It includes built-in functions to automatically compute both the Polarisation Index (PI) and Dielectric Absorption Ratio (DAR), useful indicators of insulation quality and aging.

Q3: Is the device safe to use on energized circuits or in wet/harsh environments?
A3: It is rated IEC 61010 CAT III, 600 V; with IP54 protection for field conditions. There’s also a safety feature: if the object under test has a residual voltage above ~25 V, measurement is automatically inhibited.

Q4: What power supply does it use, and what is the battery life?
A4: It uses 8 LR14 batteries, providing up to approximately 21,000 insulation tests of 5 seconds each when fully powered.

Q5: Can it record test duration and generate R(t) curves?
A5: Yes. The CA6541 supports programmable test durations and automatically samples and stores up to 20 insulation resistance values during a test for plotting the R(t) curve.
