| Please help, FLUKE 8920A Multimeter Repair |
| << < (15/45) > >> |
| Harry_22:
Please measure the leakage by multimeter. |
| daisizhou:
Is this how it is measured? I tested the multimeter wire resistance |
| Harry_22:
Seems it's Ok. Now you need to wait and check the further behavior of 8920a... wait and check. It's such a malfunction. |
| daisizhou:
Ok, I'm going to keep testing this for a while. Frankly,The old red tantalum capacitor has a better series equivalent resistance than the new yellow tantalum capacitor.6.197 ohm(YELLOW), 2.532 ohm(RED) |
| Harry_22:
Don't be guided by this resistance. Not everything is so simple. Please see the measurement of 1.5uF capacitor and 9.8k resistor in parallel. PS You had no bias on tantalum during measurements. May be this is a reason of high Rs. |
