This volt- age directly corresponds to the readout dials digit value for the particular reference supply voltage being used. Califmnia Barnes Corp. The John Fluke Mfg.

Remove the upper and lower dust covers from the instrument. Personally, I found this argument questionable. If the com- mon mode voltage is greater than 50 volts, the meas- urement vluke be made several minutes after the equipment connections for best accuracy due to the time required to charge the stray capacitance through the extremely high leakage resistance to ground. The Model A is a portable unit, half-rack in width, with a tilt-down carrying handle.

Instruction

The lamp DSl functions as a ballast to limit charging current at an optimum value for rapid charging of BTl. A Use Code column is provided to identify cer- tain parts tliat have been added, deleted, or modified during production of the Model A and AR, Each part for which a use code has been assigned may be identified with a particular instrument serial number by consulting the Use Code Effectivity List below.

Wlien performing these checks it may become necessary to replace component parts in order to ob- tain the desired results.

The input power trans- former primary is composed of two windings which, when connected in parallel, allows the instrument to be operated from a volt ac power line or, when the windings are connected in series, allows the instru- ment to be operated from a volt ac power line.

This fuse is located on the rear panel assembly of the instrument in a bayonet fuseholder. Email to friends Share on Facebook – opens in a new window or tluke Share on Twitter – opens in a new window or tab Share on Pinterest flkue opens in a new window or tab.

Continuous division of the reference supply voltages, while presenting a constant load to the reference supply, is accomplished with a Kelvin-Variey divider. The common-emitter stages of Q2, Q4, Q5, and Q7 provide the necessary voltage gain of the ac s: Ratings and Reviews Write a review. See other items More The remaining circuitry operates similar to the dc differential mode with the only dif- ference being the absence of the polarity reversal switching.

For DBM measurements above one volt ac, multiply the voltages listed in Figure by ten for each range and then add 20 DBM for each range.

Left or right meter deflection during dc measure- ments corresponds to a negative or positive polar- ity of the measured dc voltage. Return shipping is the responsibility of the buyer in all situations unless prearranged or otherwise described within the individual 89a.

In order to filter out the high voltage 983a ripple, large electrolytic capacitors were attached across the rectified DC node. In order to filter out the high voltage output ripple, large electrolytic capacitors were attached across the rectified DC node.

Nim 36 SiiKlii Clara. When flhke results of these checks agree with the information given, the Recorder Output Option circuitry is functioning properly and the test equipment can be disconnected from the instrument. All material in the container should be checked against the enclosed packing list. These often included switchmode boost PFC power factor correction circuits that created a roughly v DC voltage from the input v wall plug AC.

These options can be installed at the factory, upon request, or in the field. Remove the nuts from the front panel binding posts and remove the terminal clips from the binding posts.

The reference divider junction provides a sample of the and volt dc reference voltage to the dc to dc converter comparison amplifier which controls the input dc voltage to the dc to dc converter.

A resistive divider comprised of R9 through Rll provides a load for the 893z doubler when this reference voltage is not being used and func- tions as a bleeder when power is removed from the circuit.
