Fluke 87 Continuos Beeping Problem Fixed - Page 1 - EEVblog
2015年7月24日 · My Fluke 87 started beeping when I tried to use it again after leaving it sitting under the house on an aircon external unit hot and vibrating. Solder joints look fine. Small amount of debris in the receptacles. Probably just enough in the groove in the bottom corner to short the halves of the terminals.

The Durahells leak still, just they tend to dump that lovely caustic product into the terminal area after a few weeks, and then it migrates up into the battery holder contacts, and, if it is the clip type, it corrodes up the wires, or if ...
F87 error Fluke 87-v? - Page 1 - EEVblog
2018年8月17日 · BUT I have a Fluke 87-V and I left it running while I was doing a min-max using that feature. I took it off the ranging feature and left it at my bench turns out it was on, but it turned off after 30 Minutes like it's supposed too. However now, every time I flip the dial on I see F87 and the high voltage warning on the side you usually get when ...
Buying used Fluke 87 V, how to know if it's ruined - Page 1
2018年10月2日 · Waiting to buy a Fluke 87V for $30-$50 is unrealistic when they are around $400 new. You make it sound like everyone is selling broken multimeters out there. Just to get any hint of fanboyism out of the way, for years Fluke was my brand of choice. I used 8020, 8060a, original 87, 87 III, 87 V, 73 II, Scopemeter 97.
Fluke 87V displaying "Lead" and sounding beeper when nothing
2012年7月15日 · Re: Fluke 87V displaying "Lead" and sounding beeper when nothing is plugged in. There is also one other thing to look at when you have a unit with this issue. After taking the unit apart have the board face you like normal. To the right and just above the (+) input terminal is a white ceramic resistor network.

2021年8月15日 · my Fluke 87 won't read resistors under 6 ohms,shorting the leads. shows about 6 ohms where before it was less then 1. probing the ma. input in ohms reads 1005 ohms and 6 at the 10a input. I recently checked. a car batteries voltage while in ohms mode. everything else seems ok. its an older model 87 before they had battery doors.
Fluke 87-V stuck on BATT and never turning off - Page 1 - EEVblog
2019年9月17日 · Re: Fluke 87-V stuff on BATT and never turning off. It seems the rotary switch is passing a voltage from a voltage divider to select modes. I had failed devices which use the same scheme. Problem is if one resistor is bad, the whole thing behaves weird. Check the resistor divider network on page 41 B8/7.
Fluke 87-V "Err EEpr" MCU (MSP430F448) Programming - Page 1
2024年7月24日 · It's possible that the internal EEPROM on the MSP has a hardware fault which would require replacing the MSP of course (and obtaining the firmware to program). Still most likely to me would be "only" corrupt data in the EEPROM (values that are out of range or data structure makes no sense so firmware throws an error).
