In what form nist calibration certificate will look like, is it in paper form or a sticker? also can i leave it on for a couple hours at time?

Hello, The calibration certification comes in paper form. We do not recommend leaving the device running for more than 8 hrs as this will fill up the memory space and may cause the data to become corrupted.

Can the software that comse with this unit complete a Time Weighted Average exposure?

Software did not come with it and downloading the software has been nothing but an issue.

A**R

Great instrument, did not meet my needs. I give 5 stars to the supplier.

The instrument was easy to use. Unfortunately the instrument could not record the very low sound levels that I needed to record. ( I am talking db level not frequency.) I wrote email to supplier explaining the problem. They authorized me to return the instrument. They fully refunded and paid shipping. They were very prompt. I give 5 star rating to the supplier for customer service.
