ESR (Equivalent Series Resistance) measurement of high capacitance EDLC (Electric Double Layer Capacitor)
QCan I measure the ESR of 3F EDLC at 100Hz and 1kHz using the IM3536 LCR Meter?
A
Conditions required for safe measurement of voltage exceeding 1000V DC [ DMMs, Clamp on meters ]
QThe 1500V range of my CM4374 is CAT IV 600V/CAT III 1000V. Is there any requirement for safe measurement?
A
Negative resistance value on a DMM
QMy DT4253 displays "-40 ohm" in resistance measurement. Why does this happen?
A
Timer calibration of withstanding voltage tester
QI would like to calibrate the timer of the 3153. When I set the timer to 1s, it takes about 1.3s to confirm the output voltage. Is the unit defective?
A
Can I use the heat flow sensor with the LR8515?
QCan I use the Z2013 Heat Flow Sensor with the LR8515?
A
Difference between the LR8431 and LR8432
QIs there any difference between the LR8431 and LR8432 other than heat flow measurement?
A
Measuring current using the DT4281 and 9010-50 (clamp)
QI would like to measure current using the DT4281 with the 9010-50 Clamp On Probe. How should I set the DT4281?
A
Cannot install the LR5000 Utility (Windows 10)
QI cannot install the LR5000 Utility on my Windows10 PC. The .NET Framework 4.7 is already installed, but ".NET Framework 2.0 is necessary." appears.
