Fluke PM3082 Oscilloscope 4 Channels 100mhz No Cable
All circuit boards removed from the instrument must be gluke protected against damage, and all normal precautions regarding the use of tools must be observed. A second input signal ZT determines the intensity Z component of the text information. Page The horizontal MTB deflection coefficients can be varied in steps such as done in 6. There is a certain instability in the starting point, the so called jitter, of the DTB.
Verify that the delay difference between the two displayed signals is less than 0. The sections partly make use of the same components: ATCAL can supply several accurate voltages that are used for vertical calibrations.
PM User Manual – PM Oscilloscope from Fluke
Its function is identical to that of the other amplifier half. Remove all superfluous soldering material. For installation, reverse the sequence. These names make it easier to trace a signal going from one circuit diagram to another.
Error Calibration step Input Control signal Output Printed circuit board lay-out of external trigger unit Comments to this Manuals Your Name.
Otherwise the component is located on the side with small components. Table Of Contents 6. Apply a video signal to input CH1 with an amplitude of about 1V synchronization pulse Press the CAL key for a few seconds to start the autocal procedure.
Page – Z-MOD pm308 Properties expressed in numerical values without tolerances, ranges or limits stated, represent the characteristics of an average instrument. The output signals are measured ppm3082 the X-deflection plates of the CRT. This gives a time-linear voltage across the capacitor; the so- called sawtooth or sweep signal.
The error code lists are a usefull help in faultfinding; in many cases a displayed error code will point to the pm30822 circuit part. This is present on all 4 channels. As alternative you may use the fast-rise output of the square-wave calibration generator. If not present install 2 penlight Flke back up batteries in the holder at the rear panel of the oscilloscope.
The display part and power supply must be OK.

Synchronization is achieved via SCL. Before soldering, bend the wires through the holes of the solder leads, or wrap the wires around the leads in the form of an open U, or, maintain wiring ridigity by cable clamps or cable lacing. Servicing described in this manual is to be done only by qualified service personnel.
To reduce the rise of electric shock donot perform any servicing other than that contained in the operating Page Page – Horizontal deflection; X deflection coef Turn on the oscilloscope under test. Impedance converter This active stage consists of three sections with different frequency ranges. This eliminates calibration inaccuracies due to temperature changes.
On the power supply unit there are many parts that carry dangerous high voltages.
