How can the 3665 measure LAN cable length?
QHow is cord length measured?
A
There’s a difference between the measured value and the inverter’s display value.
QI measured the secondary side of an inverter with a 3285 (3284), but the measured value differs from the value displayed on the inverter.
A
New standard for test probes
QI heard that the IEC 61010 international safety standard for measuring instruments has been revised. What has changed?
A
Please tell me about the internal resistance of analog testers.
QThe specifications of the HiTester 3030-10 and Multi Tester 3008 indicate an internal resistance of 20 kΩ/V. Please tell me about the effects of the tester’s internal resistance.
A
Inability to start a withstanding test
QWhen I try to start the test, measurement does not start.
A
Current dependency and voltage dependency
QWhat can you tell me about sample current and voltage dependency?
A
Loss due to the instrument connection method
QDo measured values vary with the power meter connection?
A
Differences between the 3390 and 3390-10
QHow do the functions of the 3390 and 3390-10 differ?
A
I’m unable to use USB communications with the LR8431.
QI purchased an LR8431, installed the Logger Utility, and connected the instrument to my computer with a USB cable, but the computer won’t recognize the LR8431.
