Proper energy meter configuration is essential to maximizing data accuracy and overall project success. At Accuenergy, we are committed to helping you set up your Acuvim II + AXM-WEB2 as quickly as possible so we’ve created a How To Video Series where we break down the setup process into easy-to-follow sections. Our short walkthroughs will teach you to efficiently navigate our web interface and get the most out of your metering devices.

Acuvim II + AXM-WEB2: How to Configure Time Using the Built-In Web Interface

The Acuvim II Series power meters include a real-time clock so that all events and logged data can be accurately time stamped. In this guide, we will walk through the steps to configuring the time settings for the meter’s internal clock using the built-in web interface.

To complete these steps, you will need an Acuvim II meter with the AXM-WEB2 module powered up and connected to an internal network or the Internet plus the IP address of the device.

Step 1

Enter the IP address of the AXM-WEB2 module in your web browser. This will take you to the Accuenergy Login screen which prompts you for an Access Level and Password. Select “Admin” for the Access Level and enter the case-sensitive password for your module (default password: admin). Click the “Sign In”

Step 2

Upon logging in, you will be taken to the Dashboard screen. Click the “ Settings” button in the upper-right corner of the page.

Step 3

Once in the Settings screen, click on the “Communications” tab at the top of the page.

Step 4

From the Communications screen, select the “Time/Date” tab.

Step 5

The module’s clock can be set manually or synchronized with an NTP (Network Time Protocol) or SNTP (Simple Network Time Protocol) server, which will automatically update the module’s clock to match a time server.

Set Manually: To manually update the module’s clock, ensure that the “Disable” radio button is selected under “NTP Enable.” Then, click on the “Device Clock” dropdown menu to choose the correct date and time. Next, select the correct time zone from the dropdown menu. Or simply click on the world map to select the right time zone.

Set Automatically: To automatically synchronize the module’s clock with an NTP time server, select “Enable” under “NTP Enable.” Next, select the NTP Type by selecting the “NTP” or “SNTP” radio button. Important: Select “SNTP” to maintain IEC61850 protocol compliance.

Once enabled, the clock will be automatically synchronized with the NTP server every 5 minutes. You may also synchronize the time immediately by clicking the “Force Update” button.

The module can synchronize with up to three different time servers. If a time server happens to be down, the module will attempt to synchronize with the alternative servers selected. Enter server preferences in the “NTP Server 1,” “NTP Server 2,” and “NTP Server 3” text fields. To find a list of NTP servers based on region, visit

Next, click on the “Device Clock” dropdown menu. Click the Star icon in the lower left corner of the dropdown menu to directly set the day and time.

Step 6

Once the day and time settings are correct, click the green “Save” button at the bottom of the page. For the settings to take effect, the module must be rebooted. You will be prompted to either “Reboot Now” or “Reboot Later.” If “Reboot Later” is selected, the module must be rebooted from the “Management” page.

Step 7

If “Reboot Now” is selected, the module will begin the reboot process right away. Click the “OK” button to log out from the web interface.

Step 8

The reboot process takes 1-2 minutes. Once the process is complete, you may log back in again to confirm the settings have taken effect. Follow the same login process outlined in Step 1, then click Settings > Communications > Time/Date to review the settings.

Step 9

Click the “Management” tab at the top and scroll down to Device Clock. Ensure the time and time zone are correct. If NTP is enabled, wait for the NTP interval to check whether the time successfully synchronized.

Step 10

After the settings are confirmed, you may log out again. This completes the Time Configuration process.
