Click on the departments below for their list of FAQS:


Looking to order equipment that is not listed on our website?
Advanced Test Equipment Corp has relationships with a vast network of test equipment sources, both domestically and world-wide. Let us know your requirements.
Has the equipment I ordered from Advanced Test Equipment Corp been tested?
Equipment will typically be quoted and assumed as ‘Functionally Verified’. We find that the majority of our customers either have their own trusted third-party lab or their own internal calibration lab, and prefer the equipment be calibrated through these channels.  Most appreciate not paying for the additional overhead that would have to be applied to each unit if Advanced Test Equipment Corp calibrated each piece in our inventory.

For those customers that need the equipment calibrated, Advanced Test Equipment Corp will certainly accommodate you. There is typically an additional charge and extra lead-time for this service.
Can I purchase items from Advanced Test Equipment Corp even though I am not located in the United States?
Yes. We are a worldwide supplier of quality test equipment.
What is the lead-time to ship my equipment after my order has been placed?
At Advanced Test Equipment Corp we understand our customers’ need to have their equipment shipped quickly and on-time. Lead-times generally vary from one day to two weeks and are noted on our quotation to you. Please be sure to discuss your more urgent requirements with your sales representative so we can be sure to meet your expectations.
Can you provide international packing and shipping?
Yes. We have experience with the changing and ever more stringent intricacies of international export laws. Our shipping department securely packs your instruments so they arrive at their destination safely and ready for use.
Do you offer local delivery?

Why did I receive an invoice?  I returned the equipment.
If the equipment is not returned at the end of the billing period, the customer will be billed at the beginning of the next billing period.  If the equipment is returned during the next billing period, a credit memo will be generated based on the return date, prorated by the return date. The credit will be applied to the final invoice. The net balance will be due.
I am not sure of what I am being charged. Can you help me understand my bill?

Prepay via Master Card, Visa, American Express, Discover or Wire Transfer. Net 30 terms may be granted upon credit approval. Net 30 terms require an ATEC credit application to be completed and submitted for approval.
Do I pay for shipping charges?
