How do I replace battery on a mitutoyo 500-130 digital caliper?

I also have a Mitutoyo 500-422 Caliper. But mine is strictly solar powered. There is no battery for it. So long as you have 60 lux of illumination on it, it will work fine. Its not suited for darker environments, as it will lose its measurement when the light falls below 60 lux.

Try your fixya search again spelling it mitutoyo.

Find the little battery compartment on the back. Slide it open, tap lightly against your hand to drop the battery out. Insert a correctly-rated new replacement battery in the same orientation as the original battery. Slide the cover back on. They make it about as simple as possible.

The Mitutoyo 500-115 caliper does not have an off button. It automatically shuts off after two hours of non use. Very frustrating since after just a few times of using the calipers 6+ hours of time has been used on the battery and consequently it doesn't last long. I am in the middle of adding a switched battery holder to my calipers. I have already milled a channel for the wires and tomorrow I do some soldering and two sided 3M tape to mount it to the back. The switched holder is Adafruit 12mm Coin Cell Breakout w/On-Off Switch [ADA1867]. The battery you should use is 1.55V Number 390 (Energizer). We'll see how this turns out. Sick of putting batteries in it. Go figure total cost of all of this is around $15 which includes a new 390 cell from the hardware store. That's about 5 years worth of batteries. Maybe it's the principle of it. At lease now if/when I do replace the battery, no disassembly required.

The battery is just under a slide cover. You can zero it but to recalibrate you would have to send to a standards lab. The lab calibration would cost more than a new caliper so you really need to justify it. Basically if it is out of calibration just replace it, they are not really worth the money to recalibrate.

Sounds like the new battery you installed is no good. Is the display also dim? When the battery is low that is one of the results on the Mitutoyo. Do you have another battery to try in it?

The battery compartment is on the front of the instrument. The cover is round and has some symbols that resemble arrows pointing down. Slide the round cover down to access the battery.

There should be a battery cover on the back of the case that will have a small release catch on it that will open the compartment up. Mine has 2 batteries in it. Hope this helps you.
