This Conformity is indicated by the symbol , i. Specific warning and caution statements, where they apply, appear throughout the manual. The following international symbols are used on the test tool and in this manual:. Since the adapter is isolated, the line cord does not need to be equipped with a terminal for connection to protective ground.
Since line cords with a protective grounding terminal are more commonly available you might consider using these anyhow. To avoid electrical shock or fire if a test tool input is connected to more than 42 V peak 30 Vrms or on circuits of more than VA:. 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. The following example shows how to use the test tool's menus to select a function. Subsequently follow steps 1 through 4 to open the scope menu and to choose an item. This toggling enables you to check the labels without affecting your settings. 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.
Select On When you select Envelope: On , the test tool displays the. 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 Glitch Detect to Off will suppress the high frequency noise on a waveform.
Averaging will suppress the noise even more. Select Glitch Detect: Off , then. 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.
The variable input sensitivity allows you to adjust the sensitivity continuously, for example to set the amplitude of a reference signal to exactly 6 divisions. The input sensitivity of a range can be increased up to 2.
An Auto Set will turn off the variable input sensitivity. You can now select the required input range. Actually I think it could be a candidate in that ugly repair thread which is going at the moment Free Electron also suggested checking a small switching transistor V if it wasn't charging, I'm pretty sure its the one I've marked in the last photo and a quick check with a DMM on diode mode indicates its still OK.
I think I'm The next issue is souring a replacement connector, I'm in Australia and Fluke don't sell spare parts direct you have to buy via the Australian repair agent. On further thought this is probably why the previous owner did the bodge repair instead of just replacing it in the first place.
I'm not sure if Fluke parts are just expensive because they are Fluke or I'm paying a special privilege because I live in Australia and have to buy through a distributor. Before I succumb to buying one locally can anyone in the US check what the Fluke price is for this part for me?
Thanks for your help if possible. NZ Siglent Distributor. What's the diameter of the DC plug? Will Jaycar PS work? RS or Element14 should be able to help with this. Thanks for the comments Tautech, the power plug is about 5mm dia with a 2mm bore but slightly different from your run of the mill DC power plug as per the attached photo.
Today I decided to remove the connector so I could take some better photos of it for comparison with others that are available. I'm pretty certain that the Fluke part is going to be the only thing that fits properly as its made so that it keys onto the board and also has some pins on it which hold a sealing gasket in place to seal it up to the top casing of the meter as well.
Once I had taken the connector off the board the bodge wire came free straight away and I could see that it was clipped together. So I decided to pull it apart to see if there was a way I could just replace the centre pin of the connector. I found there's a sealing O-ring inside the connector to seal the plug part from the back which in conjunction with the other gasket is to maintain the IP rating of the meter and I guess is part of the reason they want to charge so much money for a new one I then tried to put a bit of heat onto the end of the pin which has broken with the aim of trying to melt the solder and see if I could get a bit of wire into the back of the pin.
However I ended up separating the pin from the plastic end of the connector which is not the end of the world as I pushed it outwards opposite to the way the plug will normally push on it but it means I can hold the pin in a pair of pliers now. I tried heating it and doing the bang on the desk trick but couldn't get the broken bit of wire out but at least I can see that the pin is hollow at that end.
So my latest plan is to get some micro drill bits tomorrow from a hobby shop and try to drill out some of the broken wire in the end of the pin so that I can insert my own bodge wire into the broken pin. Then hopefully I can reassemble the connector may need a bit of superglue to retain the pin back in the small plastic bit and just refit the repaired connector.

Calls attention to a potential danger that requires correct procedures or practices to prevent personal injury. The following symbols are used on the test tool, in the Users Manual, in this Service Manual, or on spare parts for this test tool. Whenever it is likely that safety has been impaired, the test tool must be turned off and disconnected from line power.
