How To Guide

Getting Started

This is a quick 3 minute read on how to register, download, and get started.



Click on "Register" in the navigation bar above. Decide account type. A user account is for a single user who may eventually use and or make limited purchases. A manager account is for a person who may manage many user accounts and or make many purchases of 1 or more copies. If you register as a user, you can switch to a manager with a simple e-mail request. If you are a technician calibrating in a lab and decide to use Power Freq, you have the option to join your manager’s group. If left unchecked it is very easy to join a group at a later date. Fill out all the necessary information and you will receive an email with your registration code.

Download & Install

Once registered and logged on, click on "My Account >> Downloads >> Power Freq". Your download will take place instantly. After it finishes click the setup.exe file, and follow all the prompts, to install. Once installed it will show on your desktop. Click "Offline" and enter your Username and Registration Code from your email or the Download section from My Account. That’s it! It takes typically about 5 min or less to get up and running!

Transfer License(s)

If you have made any purchases click "My Account >> Transfers", you will be able to see how many copies of license(s) you have and the number of transfers available per license. In the tab directly above, "Managed Accounts" is a layout of the users in your group and the license(s) in their group. Lets say you have an account with 2 users Tom & Jerry. You have made a purchase for the 8845A & 8846A. You decide to issue them both to Tom. Select your username from the "From:" dropdown and select Tom from the "To:" dropdown, increment 8845A & 8846A and click "Transfer". For Tom to receive his new licenses he must open the Power Freq desktop app and click "Offline >> User >> Check for Updates" and follow the prompts. If you decide to transfer those same licenses from Tom to Jerry, follow the same procedure "To:" goes to Jerry "From:" goes to Tom. To finish the process Tom must initiate Check for Updates first in Power Freq, then Jerry does the same in his desktop app. Any additional purchases made may be transferred to any user within your group at any time. All transfers reset every year from the date of purchase. A single license purchased (Ex. 34470A) has 1 transfer per year. A series license purchased (Ex. 344xxA Series) all instruments in that series can be transferred up to 3x per year.

Transfer Users(s)

If you are a manager and have users you wish to join your group, the easiest way is when they initially register their new user account click on the join your manager’s group box and fill in the manager’s username. If not, to transfer an active user click "My Account >> Add Users", fill out the necessary information, click "Send Request". They will receive an email, and follow the instructions, which are to login to their account and enter the transaction code they received. Once done they are added to your group. Click "My Account >> Managed Accounts" to see users in your group and the license(s) they hold.
