Their obligation under this Warranty is limited to servicing or adjusting an instrument returned to the factory for that purpose, and to making good at the factory any part or parts thereof; except tubes, fuses, choppers and batteries, which shali, within one year after making delivery to the original purchaser, be returned by the original purchaser with transportation charges prepaid, and which upon their examination shall dis- close To their satisfaction to have been thus defective, f the fault has been caused by misuse or abnormal conditions of operations, repairs wiii be billed at a nominal cost, in this case, an estimate will be submitted before work is started, if requested.
So it’s probably around 40 years old. In the case of optional sub- assemblies, plug ins, etc.

AC DC Differential Voltmeter A Equipment Fluke, John, Mfg
The resistive network of R17 through R19 form a divider across the output of the zener current regulator and provides a sample of its output voltage to the base of Q9. At the end of this period, the volt- ages across the transformer windings are reversed fljke the collapsing lines of flux, driving transistor Ql into cut-off and Q2 into saturation, thus establishing the second half-cycle of the 3 kHz signal.
See the picture below. I Model serial number thru These often included switchmode boost PFC power factor correction circuits that created a roughly v DC voltage from the input v wall plug AC. DC Input Divider Sabah East Malaysia P.
Ratings and Reviews Write a review. Paterson, NJ Tei. A personnel hazard does not exist as the source resistance is 90 megohms on the ono A and volt ranges, however, this potential can damage high input impedance semiconductor devices such as field effect transistors.
Report item – opens in a new window or tab. Adjust A2R35 for an indication of 1. The output of the differential connected comparison amplifier controls the conduction of the series-pass transistor Q7 and determines the output voltage of the zener current reg- ulator.
These often included switchmode boost PFC power factor correction circuits that created a roughly v DC voltage from the input v wall plug AC. To calibrate the AC Converter, apply ac power to the instrument and proceed as follows: Rotary switch S6 89a the first order division of flukee reference flluke ply voltage. This item may be a floor model or store return that has been used.
The manufacturer will not be responsible for shortages against the packing sheet unless notified immediately, If the instrument fails to operate properly, or is damaged in any way. In general the reference designations are listed under each as- sembly in alpha-numeric order. My purpose-built lab circuit probably had a higher impedance than this. Conduction of Q3 and Q4 is con- trolled by the 3 kHz drive signal applied to terminal 4. Virrey del Pino 1 Buenos Aires.
The meter pointer should deflect above and below the minus 1 indication. Standard components have been used wherever possible. A graph of these apparent off-null input re- sistances is contained in Figure Burbank, CA Tei.
Note that the electromechanical nulling meter will tend to average out AC ripple the needle can’t move instantaneously.
For example, it could be that the two capacitors used in my t. The meter pointer should deflect in the opposite direction by approximately the same a- mount observed in step b. The iiput circuit erf the AC Converter is conposed of R12 and a capaetty conpen- sator which maintains a high input inpedance erf cxie meg- ohm shunted by less than 20 pf for all ac ranges. Co X6 f in it! The manufacturer will not be responsible for shortages against the packing sheet unless notified immediately.

You can insure prompt and efficient handling of your order to the John Fluke Mfg. Puerto Rico Q Tel. For replacement, order Reference Divider Resistor Set, part number Transistor Q2 is the series- pass element whose conduction is controlled by the series-pass driver Ql and the two differentially con- nected conqjarison amplifiers of Q3, Q5 and Q6. Box Seoul, Koree Tet. Resistor R14 provides adjust- ment of this reference voltage. Adjustment of this compensator will affect high frequency calibration of all other ac ranges.

Subassemblies of minor proportions are sometimes listed with the assembly of which they are a part. J Netherlands Tol. Misadjustment of this control will produce null detector open circuit offsets particularly notieable on the. Left or right meter deflection during dc measure- ments corresponds to a negative or positive polar- ity of the measured vluke voltage.
