	Good day Could any one tell for how long (maximum time) FLUKE 435 with 8GB SD card can record data before downloading.

	I suspect this all depends on how one configures the instrument to capture data. Configuring it to capture a brief time interval (30 sec?) of "good" power quality once but then the same time interval before and after a preset anomaly trigger level will allow this to be monitoring until its batteries die. __________________ "Don't disturb my circles." translation of Archimedes last words

	What redfred said. Sample rate must be considered, size of data file, etc, etc. Too many vairables to say. Get a 32 GB sd card.

	Depends on several things. Are you planning on capturing wave events/transients that exceed certain limits? Those capture events are at 200 kS/s. You are able to capture up to 9,999 waveform events. Depending on how you set your limits, you may get a lot or very few waveform captures. Logging data of course uses a lot less memory. And that will depend on how you set your averaging time. The default is a 1 second averaging time. The range of logging intervals is 0.25s to 2 hours. If you log data every 2 hours, you will be dead long before you fill up an 8 gig card. The best thing to do, is to set up the instrument with your configuration and let it run for an hour. That will give you a yardstick to estimate the duration that an 8G card will collect data.

	It tells you on the start page menu how much time you have according to the sample rate you've chosen.... __________________ All living things seek to control their own destiny....this is the purpose of life

	Yes. The equipment manufacturer will be happy to help over one of those under-utilised facilities these days - the telephone call. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856
