FLUKE PM , PM , PM, PM ANALOG OSCILLOSCOPE SERVICE MANUAL. Find great deals for Fluke PM Oscilloscope 4 Channels mhz No Cable. Shop with confidence on eBay!.
Use desolder braided wire; ordering code: Here, the accuracy of this range is checked. Check that the leads of the replacement part are clean and pre-tinned on the soldering places. For instruments with switchable input impedance it is recommended to make use of this feature. Table of Contents Add ppm3082 my manuals Add.
PM 3082 Oscilloscope
CHIP The IEEE p3m082 is located at the rear panel of the oscilloscope. It controls all oscilloscope functions and receives input signals from the following sources: Circuit diagram of external trigger unit This procedure is intended to: Over and under-voltage protection To protect the oscilloscope circuitry against over-voltage and the supply circuits against overload, the power supply is provided with a protection circuit.
Error Calibration step Input Control signal P3m082 Then take care that its screen is pressed tight to the front side of the chassis. Each data block sent by the microprocessor is preceeded by an address on which the device can respond.
If working on the unit under live condition cannot be avoided, it must be done by a qualified technician who is aware of the dangers involved. The maximum allowed jitter is checked in this test. A range of much finer steps can also be selected. Use the internal termination when avaialble. Synchronization is achieved via SCL. Page bcc U p BCC: This takes approximately one minute. The error code lists are a usefull help in faultfinding; in many cases a displayed error code will point to the defective circuit part.
Adjust the input signal to an amplitude of exactly 6 divisions. Rough handling or scratching can cause the CRT to implode. Page The linearity of the vertical amplifier is checked by moving a signal with a fixed amplitude vertically over the entire screen area. Impaired Safety-protection Components which are important for the safety of the fluek may only be replaced by components obtained through your local FLUKE organisation.
Page The oscilloscope must be capable of displaying signal amplitudes that are larger than the screen. Some of these voltages remain some time after disconnecting the instrument from the mains. These names pm30082 it easier to trace a signal going from one circuit diagram to another. The trigger sensitivity depends on the amplitude and frequency of the trigger signal. Recommended Test Equipment Note: The linearity of flukke vertical amplifier is checked by moving a signal with a fixed amplitude vertically over the entire screen area.
PM User Manual – PM Oscilloscope from Fluke
Page Verify that the deviation from the ideal straight line does not exceed 0. In this test, the values of frequency and voltage are checked. Its function is identical to that of the other amplifier half. Set CH1 to 0. Refer to section 8. The output signal from the delay line is applied to the input pins 6 and 9 of amplifier IC D Sensitivity MHz 1.
The balanced input signal for triggering on vertical channels 1,2, 3 or 4 is applied to pin 7 and 8. Within 2 minutes the instrument automatically does its main calibrations. Signal Delay Note 3: The driver transistors are V and V Apparatus should be properly grounded through the protective ground conductor of the power cord.
The HF section for frequencies above 5 kHz. Verify that the deviation from the ideal straight line does not exceed 0. The output signal is voltage and is applied to the vertical deflection plates of the Pj3082. Input Characteristics Note 1: Apply a video signal to input CH1 with an amplitude of about 1V synchronization pulse CHIP C Location of options Y-out and external trigger Manual calibration data are protected by a keyword and a seal and must be changed by qualified personnel only.
