    Anyone know how to take apart a Fluke T100 Voltage Tester without damaging it?

    See attached picture. I have a Fluke T100 Voltage Tester that the resistance and diode measurement isn't working (it's not the batteries (as I have already checked them and put decent Duracell 1.5V AAA batteries inside it).
    I have looked on the web for any information and on youtube without any results for this model.
    There are no screws visible or anything obvious. So I am hoping someone here has the solution to take it apart?
    The only way I can see is underneath the yellow rubber handle area, however I don't wish to damage it if it isn't the case!

    What is inside this hole? Maybe a screw. I can't tell what it looks like, add pic with the battery compartment open.
    Fluke T150 has covers over the screws like in these pics I found.

      Looks like only two screws in the back.

        That is the different model T150 that has two hidden screws in the back. OP's T100 is different, has a hinge for the battery compartment but need to see inside that.
        First the yellow clamshell comes apart I think, then the red end gets freed up.

          I agree the yellow plastic part needs to come apart from the main red part. I have looked carefully inside the battery compartment to see if there are any screws that would allow removal, unfortunately nothing obvious as you can see!
          I have also removed the black cap on the front of the unit to see if there was any screws under that. No joy there either.
          The whole you refer to is only a plastic cutout to allow the black probe to be stored inside as pictured in the last couple of images. There are no screw holes there either or blanking pieces!

            I think you'll have to take one for the team, I can't find any Fluke T100/T120/T140 teardowns or repairs.
            My money it's gonna be the black round button pads on the side, screw hidden underneath them. But you say nothing is there? Look harder maybe.
            Next would be prying along the sizes using a spudger. You can squeeze it and see how it flexes.

            Your red probe is cracked and at some point it won't be so safe to use at say 600V. Kinda in rough shape.
            Usually the black wire breaks at the end and goes open-circuit.

              maybe the part with the grips peels off first . it looks like the seam doesn't go all the way through that part .

                I decided it wasn't worth the time to crack this open as it was in pretty poor shape to start with! I believe the softer yellow plastic rubber type material on the grip is the way to go as nothing else is obvious.

                  Pop up that black knob. After that you can pull red part off.

                      I don't have the model now it was sold on ebay a while back! I cannot see what you say would work as I did remove the black plastic cover and did try to pull apart the unit, it didn't budge under a lot of pressure. The only way I would see it working was if you were to push a metal or strong pin into the hole possibly releasing the red plastic somehow. Too late to try now.

                        Trying to troubleshoot DDR4 SODIMM slot with slot tester
                        by Lifeisfun
                        Hi folks!
                        I have some kind of memory problem on Lenovo laptop. I was initially able to install windows after several tries since the laptop did freeze in middle of those attempts.
                        Eventually I discovered that it was related to moving the laptop.
                        Later on it even stopped booting unless I pressed around the memory slot. (no keyboard LEDs only power button responds)
                        If I remove the RAM I get the beeps that RAM is missing. Inserting the RAM there is silence and it will not boot most of the time. No picture.

                        I removed the board got one of those memory slot testers...

                        Reverse engineering of 18650 4-channel tester
                        by spleenharvester
                        Hi friends

                        I have reverse engineered this tester, schematic is attached and is complete except for capacitor values. These testers annoyingly have no model number but they are the ones you find on the first page of just about any website if you type in "18650 4-channel tester". There is also a 2-channel variant and a newer 8-channel variant. They are very cheap (about £15) and can measure voltage, current, internal resistance and capacity. They have a multicolour display for all these statistics. They also have terminal blocks so that if you want to use a breakout board...

                        I got this device yesterday and did some testing on some tabbing and some incandescent light bulbs and it seems to work very well from what I can tell but how do I know how accurate the m-ohms section is what can I use to verify it accurately I also tested some li-ion battery cells and this seems to be fairly accurate because I have another tester and they seem to agree with each other

                        I also checked some capacitors with it that were brand new and seem to show about what I expected to see with my blue capacitor tester so I think it...

                        Fluke 123 no image on the screen
                        by Khoja
                        Hello experts,

                        I recently purchased a used Fluke 123 Industrial Scopemeter from an online Japanese auction site (jauce.com). It has now been delivered. Unfortunately, I overlooked the fact that the seller neither guarantees its working condition nor accepts returns.

                        When I power it on, the backlight comes on, but there is no image on the screen. After opening the device, I noticed clear signs of previous soldering in several areas (photos attached). It seems someone attempted repairs before.

                        At this point, I'll have to try and fix it myself. Has anyone here...

                        Modification done to a EBC-A40L 5volts Battery Capacity Tester 40A for less noise when charging / discharging cycles
                        by sam_sam_sam
                        When I first turned this battery testing machine the fan for the switching power supply was a little bit noisy but once I recapped the switching power supply board it quiet down considerably then I put a temperature controlled fan that does the mosfets control board was really noisy but now that it is cooled with temperature controlled fan that sensor was moved from the fan to the heat sink so now that the fan is controlled this way the fan runs according to the temperature of the heat sink

                        This switching power supply was really fun to recap the quality of the board was very good...
