Frequently Asked Questions
What kinds of certificates can I/will I receive?
Included with the calibration costs you will receive: In and Out of Tolerance, Before & After Readings, and Traceability. If Test Uncertainty is required, that is available for $25 per certificate.
Can you email certificates?
Yes. ISL can email .pdf certificates if the customer requests that format. If you prefer this service, please let us know when you set up your account with us.
How do I set up an account?
When you contact us to set up an account, we will request certain information. Please refer to our New Customer Documents. We will need a contact name, mailing/shipping address, type of cert requested, form of payment, and any other information pertinent to your calibration needs.
Is a purchase order required?
We highly recommend that our customers provide a purchase order with each order. If that is not possible, the customer must complete the ISL-Customer-Credit-Application and submit it with the instrument for calibration.
Is an RMA required?
No. We track instruments via our issued test number and your purchase order.
How do I obtain a quote? What information do I need to provide?
You can get a quote by contacting us by phone at (317) 787-6578, by email, or by filling out our online quote form. To get the most timely and accurate quote, we ask that the customer supply us with the Manufacturer, Model Number, and Nomenclature. If a manufacturer or model number is not available, we ask that you at least provide the range and tolerance of the instrument.
If you are asking for a quote for on-site service, technician time is included in the quote. For further information, please contact us.
What is your standard turnaround time? Are there expediting options?
By appointment only. Call (317) 787-6578 or email to arrange an appointment. If you have an emergency, by all means let us know, and we will make every effort to accommodate your needs. There are expediting options available. There is a 3-day turnaround option available for a 50% charge on top of the original calibration cost, and a 1-day turnaround option for a 100% charge. To make sure things go as smoothly as possible, rush jobs are to be made by appointment only. We also recommend that any expediting be specified on the customer’s purchase order.
What are your shipping capabilities?
Customers have several shipping options:
- ISL can receive and ship by UPS and FedEx
- Local instruments can be shipped via a local courier (at additional cost)
- Customers can drop off and pick up at our location
What happens if my instrument fails?
When an instrument fails, the customer is charged for the time used to perform the calibration. This will come with a before & after readings failed certificate. If your instrument fails, we will contact you to discuss further options for replacing the item/repairing it, or sending it back to you.
How do I establish the appropriate calibration interval?
Initial calibration intervals are established by using the recommendations of the customer’s quality department, the equipment manufacturer, the METRL publication for all M&TE and measurement standards, or an otherwise reasonable interval based on engineering evaluation.
Do you send a reminder for when a calibration is due?
Yes. ISL sends out a recall notice to customers at the beginning of each month listing each instrument due for calibration in the next two months and each instrument’s due date.
What are the ISL capabilities for on-site calibrations?
These capabilities are specified on our On-site Services page. For a more detailed list, check our Scope of Accreditation and look for the parameters marked with a note 1.
How do I schedule an on-site calibration?
Please fill out our Online Quotation Form or contact us by phone. Be prepared to provide us with as much detailed information on your instruments as possible, including manufacturer, model number, nomenclature, tolerance, and/or range. We will use that information to provide a quote and schedule your on-site calibration. Due to volume, we schedule on-site appointments at least two to three weeks in advance. However, we will try our best to accommodate emergency work.
