If necessary, adjust the associated adjust- ment to obtain the specified meter indication. The reading on the Philips meter is 9. Model AR serial number thru O Model serial number thru This answer pretty much drove me crazy.

A potential difference often exists between dif- ferent points of power system grounds. There is a meter mechanical zero. Ciditornia Adviiiiced Mediimica! Since writing this page I received a very generous email from a reader “W5JG” pointing out the following information: AC Converter Block Diagram 3- 4.

Our items are described as accurately as possible, however, should an item arrive dluke or incorrectly described, we will do our best to work with you to resolve the situation. A4R5 Adjusts the null detector gain to compensate for variations in the carrier amplifier gain, full-scale meter sensitivity, and feedback resistor tolerances. For replacement, order Zener-Resistor Set, part number 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.

This item will ship to United Statesbut the seller has not specified shipping options. These voltages are used on the and voltage ranges of the instrument.

The instrument case is connected to the round pin of the three-prong connector located on the power cord.

The voltmeter’s own impedance typically 10 Megohms may be much lower than the capacitor’s resistance.

Somewhat to my surprise, the voltage actually did divide down to extremely close to half the total applied voltage within a few volts! Refer to eBay Return policy for more details. Below is a picture of it measuring the voltage output of a new 9v battery.

Dluke the Readout dials to. To utilize the recorder output voltage, proceed as follows: TVM Range Checks If a substitute container is used, the instrument should be wrapped in fluks and surrounded with at least four inches of excelsior or similar shock-absorbing material.

Cluke reading on the Philips meter is 9. Itlinoh I’irie Teeli. Adjust A3R14 for an indication of volts dc on the dc differential voltmeter. Conventional TVM Mode 8993a the com- mon mode voltage is greater than 50 volts, the meas- urement should 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.

AC DC Differential Voltmeter 893A

But v electrolytic capacitors were not really practical they either didn’t exist or were so expensive that they could never be used. This volt- age directly corresponds to the readout dials digit value for the particular reference supply voltage being used.

Here’s the point though; if I had just remembered that I had a high input impedance voltage bridge meter which I DIDN’T remember then I might have used my Fluke A bridge to measure these capacitors’ voltages, instead of making my own bridge circuit to do the same thing. Remove the left and right front panel attaching screws and slide the front panel for- ward until free of the instrument.

All of the controls, terminals, and indicators for the Model A and the Model AR are illustrated and described in Figure and Figure This signal is used to cancel out the null detector open-circuit offset effects produced by the gate to drain capacitance of Ql.
