This suffix corresponds to an integrated circuit pin of the particular gate or function. The circuits 88100a in these paragraphs correspond to the associated detailed schematic diagrams included at the end of this manual.
In my opinion it is in very solid physical condition with no major damages to describe. This common mode potential can be caused by voltage differences in the ground lines or currents induced in them. Kl-4, ‘ Q T 3IT, 41 ,11 Offset Voltage Correction Resistors Coarse Note the fluek voltmeter reading at both settings.
DC Linearity Check California Industro T ransistor Corp. As indicated by the table in Figure the buffer gain is 1 unity for the 2 Kfl through 20 Mfl ranges and 10 for the range.
Co Brooklyn, New York Snelgrove. The compare signal can be checked at TP 17 using the following procedure. If requested, an estimate will be provided to the customer before any repair work is begun on instruments that are beyond the warranty period.
Keep in mind, however, that a 8810s within one functional area may affect the operation of another. Apply a kfl standard resistance to the input. City of Industry, California Vernitron Corp.

Box Pa ramus. Chatsworth, California General Electric Co. Use the following procedure to test the opera- tion and accuracy of the dc voltage function and its ranges: Select the range, The A front panel controls, indicators, and 810a are shown in Figureand described in Table This list presumes an availability of common electronic fluie at the maintenance site. Table lists the five dc voltage ranges and the components that control the circuit configuration to produce the proper gain for each range.

Refer to Table and apply each of the positive and negative input levels shown. The ms time designated B is the read period w’hen the reference in this case, -I volt is applied to the integrator. The buffer output passes through Q39 to an integrator, the output of which is determined by the level of input applied.
This controlled interaction between the two units ensures an accurate and expeditious transfer of data. 881a0
Specifications for the DOU are presented in Section 1 of this manual. It offers convenient operation plus optimum accuracy and resolution when frequent range changes are required.

The output code representing each range is presented in Table A calibration interval of 90 days is recommended to insure instrument operation within the 90 day specifications. For observation of the control signals on the pins of Ull or logic control gates U13, U14, and U15 the oscilloscope return can be connected to TP8, the volt supply.
The AC Converter circuitry creates an offset voltage that, if not compensated for, would create an error in the displayed value of the ac input voltage. Set dc calibrator output to 0V dc and connect its output to the input of the resistive divider. B C V5C 3H3 The deluxe test lead kit, shown in Figurecontains two test leads with probes red and black and five pairs of universal probe tips.
The A employs a system of shields and guards that function, when properly f,uke, to minimize common mode to normal mode signal conversion. Secure the brackets and retainers to the handle mounting bosses using the handle mounting screws. Phone Litho in. Remove the line-power cord from the unit. Yes, my password is:
