Manual calibration data are protected by a keyword and a seal and must be changed by qualified personnel only. The unit A1 description is split into the following chapters: If not present install 2 penlight LR6 back up batteries in the holder at the rear panel of the oscilloscope. Item Ordering code Description Mains input connector Fuse 5×20 1,6AT Contact spring single Battery compartment cover Page bcc U p Flukf The linearity of the vertical pm30822 is checked by moving a signal with a fixed amplitude vertically over the entire screen area.
All instruments have four vertical channels. Apparatus should be properly grounded through the protective ground conductor of the power cord.
The communication from front unit A4 to unit A3 occurs via buffer D A second input signal ZT determines the intensity Z component of the text information. Page 3 – Use terminations. Page 34 – Description Page – Probe Adjust signal; frequency and outpu This diagram fljke the Y-output amplifier. Theseservicing instructions are for use by qualified personnel only.
PM 3082 Oscilloscope
This diagram shows the final intensity Z and focusing amplifiers. This delay is verified in the following test. Probe Adjust signal is distortion-free and has equal intensity. Rough handling or scratching can cause the CRT to implode.
Verify that the jitter of the DTB is not more than 0. Adjust the input signal to an amplitude of exactly 6 divisions. Don’t show me this message again. CHIP C Page Probe Adjust signal is distortion-free and has equal intensity. Comments to this Manuals Your Name.
The input circuit is formed by IC D Its function is identical to that of the other amplifier half. Set CH1 to 0. 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. As alternative you may use the fast-rise output of the square-wave calibration generator.

The display part and power supply must be OK. Use the internal termination when available. Handle the CRT and its side connections carefully.
On the XYZ unit there are parts that carry high voltages. Main Time Base Description.
Use the internal termination when avaialble. Page The oscilloscope must be capable of displaying signal amplitudes that are larger than the screen.
Oscilloscope MHz PM Equipment Fluke; Eindhoven
Synchronization is achieved via SCL. The sections partly make use of the same components: For the MHz version the corresponding circuit diagram should be used. ATCAL can supply several accurate voltages that are used for vertical calibrations.
At 10 MHz; input to deselected channel equivalent to 8 div. Also the vertical CRT text signal is applied to D pin 15 and Repeat the above settings and procedure for CH3 and CH4.
