The process effectively takes the square root of the squared input signal and presents it to the input of the integrator amplifier. Allow the A to stabilize at ambient temperature for at least one-half of an hour. Virrey del Pino Buenos Aires. Remove the handle disc decal and handle from the A. If re- placement is necessary, use an AGC Vi ampere fuse for either 1 15 or V ac line power, Response Time — k! Proceed to the paragraphs that provide the troubleshoot- ing information for the problem area indicated by the fault area isolation procedure.

Kisko, New York Pawtucket. Westlake, Ohio Aerovox Corp. The display should indicate 0. Free Run allows the DOU output to be automatically updated at the end of each measurement cycle. A rugged, fast-responding 8810q with a V dc standoff makes the 80T one of the most versatile and easy-to-use temperature probes available.

Box Horreya Hehopoiis. Each flue is uniquely identified by page and paragraph numbering that relates to the accessories or a particular option. Signal requirements and characteristics are defined in the following descrip- tions. Straighten both ends of the currently installed Lockout Strip.

The basic A is capable of making only dc voltage measurements. The performance test is designed to compare the A performance with the accuracy specifications given in Section 1 of this manual.

Freeport, Illinois Miller Electric Co.

Therefore, the current no longer flows through the input lead to create the normal mode error voltage. The slope of the integrator output voltage during the integrate period is proportional to the input applied to the instrument.

During the integrate time period the DE -R. For this reason, the performance test given earlier in this section is suggested as the first step in troubleshooting.

Use Code is provided to identify certain parts that have been added, deleted or modified during production of the instrument. This common mode potential can be caused by voltage differences in the ground lines or currents induced in them. Short pins 3 and 4 of U17 together.

Chundrigar Road P O. Its function is to accept ac input signals, scale them to the selected range, and convert them to fouke dc level proportional to the true rms value of the input signal.


The following procedure is used to gain access to the interior of the A: The waveform at TP I can indicate several possible problems in the circuitry. Since U is held high, unless the K.

The following paragraphs describe various conditions which should be considered before attempt- ing to operate the A. Do not adjust R Williamantic, Connecticut Nytronics Inc. Kenilworth, New Jersey P R. The Busy flags are cleared from the DOU output and the data can be read.

Fluke F15B Digital Multimeter Remove the case retaining screws from the A rear of the case and remove the instrument from the case. Select the 20 VDC range on the A. This provides access to the calibration adjust- ments.

If reshipment becomes necessary, the instru- ment should be repackaged in the original container. However, its measurement capacity can be expanded through the use of field installable options to include resistance and ac voltage measurements.
