Do not apply voltages that differ more than V from earth ground to any input when measuring in a CAT II environment. Do not apply voltages that differ more than V from each other to the isolated inputs when measuring in a CAT II environment. Use caution when using test leads because the probe tip voltage will be directly transmitted to the test tool.
They represent. V ac rms Hz for ac sinewave applications and as V dc for dc applications. Overvoltage Category III refers to distribution level and fixed installation circuits inside a building.
Overvoltage Category II refers to local level, which is applicable for appliances and portable equipment. This chapter provides a step-by-step introduction to the scope functions of the test tool. The introduction does not cover all of the capabilities of the scope functions but gives basic examples to show how to use the menus and perform basic operations.
Follow the procedure steps 1 through 3 in Figure 2 to power the test tool from a standard ac outlet. Subsequently follow steps 1 through 4 to open the scope menu and to choose an item. To display menus or key labels, press one of the yellow menu keys, e.
Look at the top of the test tool. The test tool has four signal inputs: two safety BNC jack inputs red input A and gray input B and two safety 4-mm banana jack inputs red and black. Use the two BNC jack inputs for scope measurements, and the two banana jack inputs for meter measurements. Isolated input architecture allows independent floating measurements with each input. To make dual input scope measurements, connect the red voltage probe to input A, and the gray voltage probe to input B.
Connect the short ground leads of each voltage probe to its own reference potential. See Figure 6. The Connect-and-View feature lets the test tool display complex, unknown signals automatically. This function optimizes the position, range, time base, and triggering and assures a stable display of virtually any waveform. If the signal changes, the setup is automatically adjusted to maintain the best display result. This feature is especially useful for quickly checking several signals.
The waveform identifier A is visible on the bottom right side of the screen, as shown in Figure 7. The input A zero icon - at the left side of the screen identifies the ground level of the waveform. The test tool offers a wide range of automatic scope measurements. These readings are selectable independently, and the measurements can be done on the input A or input B waveform. Observe that the top left of the screen displays the Hz measurement. See Figure 8. To choose also a Peak-Peak measurement for Input B as second reading, do the following:.
Figure 8 shows an example of the screen. Note that the Peak-Peak reading for input B appears next to the input A frequency reading at the top of the screen. You can use the average functions to suppress random or uncorrelated noise in the waveform without loss of bandwidth.
Waveform samples with and without smoothing are shown in Figure 9. When persistence is selected, the test tool displays the upper and lower boundaries of dynamic waveforms.
Persistence , then select Infinite. Observe that the fluctuating portion of the waveform appears in gray on the screen. See Figure You can use persistence to observe variations in time or amplitude of input waveforms over time. You can use this function to display events glitches or other asynchronous waveforms of 50 ns nanoseconds or wider, or you can display HF modulated waveforms.
Switching Display Glitches to No will suppress the high frequency noise on a waveform. Averaging will suppress the noise even more.
Glitch capture and average do not affect bandwidth. Further noise suppression is possible with bandwidth limiting filters. After a reset, the test tool is dc-coupled so that ac and dc voltages appear on the screen. Use ac-coupling when you wish to observe a small ac signal that rides on a dc signal. To select ac-coupling, do the following:. Observe that the bottom left of the screen displays the ac-coupling icon:. For example, a negative-going waveform is displayed as positive-going waveform which may provide a more meaningful view.
An inverted display is identified by an inversed trace identifier at the right of the waveform. To suppress high frequency noise on waveforms, you can limit the working bandwidth to 10 kHz or 20 MHz. This function smoothes the displayed waveform.
For the same reason, it improves triggering on the waveform. A versus B provides a plot with input A on the vertical axis and input B on the horizontal axis.
The Mathematics functions perform a point-to-point operation on waveforms A and B. To suppress noise without loss of bandwidth, use the average function or turn off Display Glitches. The sensitivity range of the mathematical result is equal to the sensitivity range of the least sensitive input divided by the scale factor. The introduction gives basic examples to show how to use the menus and perform basic operations.
Use the two 4-mm safety red and black COM banana jack inputs for the Meter functions. The screen displays the numeric readings of the measurements on the meter input. The resistor value is displayed in ohms.
Observe also that the bargraph is displayed. You can measure current in both Scope mode and Meter mode. Scope mode has the advantage of two waveforms being displayed while you perform measurements. Ensure that the red and black probe connectors correspond to the red and black banana jack inputs.
When in auto ranging, the bargraph sensitivity and decimal point are automatically adjusted while checking different signals. A relative measurement displays the present measurement result relative to a defined reference value. The following example shows how to perform a relative voltage measurement. First obtain a reference value:. ON is. This stores the reference value as reference for subsequent measurements.
Observe that the main reading is displayed as variations from the reference value. The actual reading with its bargraph is displayed beneath these readings.
You can use this feature when, for example, you need to monitor input activity voltage, resistance, temperature in relation to a known good value. This chapter provides a step-by-step introduction to the recorder functions of the test tool. The introduction gives examples to show how to use the menus and perform basic operations. First choose a measurement in scope or meter mode. Now you can choose the recorder functions from the recorder main menu.
