Hi, Tim,
Thanks for the reply. I am using mine for constant recording with ‘No Wait’. Good, brand new batteries last about 3 days. I have recently been looking at LFP (LiFePO4) batteries as they have a 3.2 volt output, so no voltage regulation would be required.

Phil,
I have not seen this problem with mine, as long as the card was fully seated. However, you could notch the case where the card is. The only reason the card isn’t exposed is to meet a safety requirement due to the 600 volt capability of the meter. There would be no danger, as long as you didn’t poke something in around the circuit board while the probes are plugged in and measuring dangerous voltage. I have never liked the fact that it is necessary to take the meter apart to access the card or reset, but Mooshim announced early on that they were forced to close those off due to the above mentioned safety requirement.

Bernard,
Also be aware that the meter will use UTC for the file date as well. This can result in the file date being 1 day past the actual data.

Bernard,
Be aware that the first column in the data file will be the date-time in UTC format with time base of Jan 1, 1970.

Bernard,
If you can find one at a decent price + shipping, let me know. The best was on Amazon, but they are out of stock. I want a second so I can watch both 120 VAC legs at the mains.

Bernard,
I am currently using my Mooshimeter for exactly this purpose. It will depend on the duration of the peaks. With a setting of ‘No Wait’ I get data at about 3Hz. 24 hrs results in a data file of about 18 Mb. You can put a 32 Gb micro SD in your meter. This will give an amazing amount of recording time. Unless my math is way off, this says you should be able to get about 5 years worth of data. Of course, your batteries will not last quite that long. When the batteries get low, the blue tooth will cease functioning and you won’t be able to tell the meter to stop logging. I am not sure if this will result in a corrupted data file. I can’t tell you how soon this will occur as it depends on too many factors (type and condition of batteries, etc.). I momentarily stop logging, check battery and swap SD cards every 24 hours. I ground out the access port for the SD card with small drills and files so I don’t have to continually take the meter apart.
I hope this long-winded reply helps.
