CAT III For measurements performed in the building installation.
CAT II For measurements performed on circuits directly connected to the low--voltage installation.
CAT I For measurements performed on circuits not directly connected to

Overvoltage Category II (as defined in IEC61010-1)
A measure of the contaminates that could occur in the environment around and within a product. Typically the internal environment inside a product is considered to be the same as the external. Products should be used only in the environment for which they are rated.
Pollution Degree 1 No pollution or only dry, nonconductive pollution occurs.
Products in this category are generally encapsulated, hermetically sealed, or located in clean rooms.
Pollution Degree 2 Normally only dry, nonconductive pollution occurs.
Occasionally a temporary conductivity that is caused by condensation must be expected. This location is a typical office/home environment. Temporary condensation occurs only when the product is out of service.
Pollution Degree 3 Conductive pollution, or dry, nonconductive pollution that becomes conductive due to condensation. These are sheltered locations where neither temperature nor humidity is controlled. The area is protected from direct sunshine, rain, or direct wind.
Pollution Degree 4 Pollution that generates persistent conductivity through conductive dust, rain, or snow. Typical outdoor locations.
Pollution Degree 2 (as defined in IEC61010-1). Rated for indoor use only.

Performance Verification
To verify that the MTM400A monitor is operating correctly, perform the following procedure.
Requirements
The MTM400A monitor must be connected to a network and have a valid
IP address as described in the MTM400A Quick Start User Manual .
The client PC must satisfy the requirements listed in Table 1--1 on page 1--1.
Procedure
1.
Connect the MTM400A monitor to an Ethernet network.
2.
Power up the MTM400A monitor and wait for the instrument initialization to complete.
3.
On a client PC (connected to the same network and subnet mask as the
MTM400A monitor), launch the Microsoft Internet Explorer Web browser.
NOTE
. This procedure describes how to access the the MTM400A monitor RUI using the Microsoft Internet Explorer Web browser. The RUI can also be accessed using the Tektronix Web Monitoring Systems Manager (WebMSM). This is described in the WebMSM User Manual, Tektronix part number 071-1239-xx.
MTM400A Specifications and Performance Verification 2- 1
Performance Verification
4.
In the Web browser address bar, enter the network identity or the IP address of the MTM400A monitor, for example: http://TSMonitor01 or http://111.222.333.444.
5.
Press Enter . A Java applet is downloaded from the MTM400A monitor and launched. The file size is approximately 1.5 MB; the download time will depend on the network speed and traffic.
CAUTION.
The Java applet will not run unless a temp directory is properly configured on the PC. A temp directory is set up by default in the Windows XP operating system; previous operating systems may require operator action.
The Java applet will not run unless the Sun Java Virtual Machine is installed.
Type java -version at the command prompt to verify that it is installed and that the version is 1.6.0_03 or greater. If it is not installed, you can download the latest version from the Sun Web site, www.java.com\getjava.
If you have to update the Java version on the PC, you will need to restart this procedure at step 3.
6.
In the Connect to MTM Device dialog box, select the Login Type from the drop-down list, Administrator or User.
7.
Enter the password for the Login Type you selected in step 6. The default password for Administrator is tek; there is no default password for User.
8.
Click Connect to start the connection process.
9.
Read the End User License Agreement if it appears, and then click I Accept .
10.
When the MTM400A monitor RUI opens, click Device in the button bar to display the Device Information view (see Figure 2--1).
11.
In the Device Information view, verify that the Application Firmware
Version is 3.0 or greater.
12.
If the MTM400A monitor connects and presents the RUI, and displays the correct application firmware version in the Device Information window, then the instrument is operating normally.
