FLUKE 7250A PDF

Option package consists of a board in the A, a ribbon cable and a board for the Fluke A IEEE Translator. The 1 A must be used to interface A. Fluke A Benchtop Timer/Counter. A broadband continuously variable, x, analog attenuator lets you add just enough attenuation to minimize the input. Here you will find a large selection of new and used Fluke A listed at special prices. Although some items match several categories, all of them are listed.

In the front, press down on the BNC input vluke, while gently pulling up on the case top lip. In the A, both channel inputs are therefore ac-coupled. Nestle top and bottom instruments together. With F41ow, U 1 goes high to enable U An Instruction Manual and any accessories ordered will be included with the instrument.

Set front panel controls to: The Static Sensitive S. The result is displayed without measurement units annunciation.

As frequency increases, accuracy increases. Each block performs the following operations: Compensation Effects Table Period Average Test Disconnect the power cord and any other connection e. The display should remain unchanged. During event timing functions, an internal oscillator frequency is counted for a period determined by the input signal. Low Battery Voltage Relay Circuit This function enables the Main Gate at a rate determined by Control Logic.

Showing Results for Fluke 7250A

Figure illustrates clocking logic. The one count ambiguity, inherent in any gate and counter type of frequency meter, results from an out-of- phase relationship between the input signal and the internal oscillator signal.

Apply power to the counter and allow. A complete list of these service centers is included in Section 7 of this manual. The number of pulses of the Channel A Signal counted during the fulke gate enable is then displayed without measurement unit. The operator should be aware of all facets of the 72250a sources and exercise discretion in using the instrument to make precise measurements.

If the instrument is damaged in anyway, a claim should be filed with thecarrier immediately. When using these guidelines, the operator must exercise discretion. These figures apply when in 0.

As the input is reduced through 10 mV rms, the display should remain stable. When reinstalling the Flukke Conditioners or the Front Panel Assembly, care should be taken not to bend the connector pins.

Y Instrument Cable, 5 ft. Refer to Figure for the following block description.

Vary the input level between lOmVrmsand IV rms; check for a proper display at all levels. The A is contained in a molded instrument case with non-marring feet, a tilt-down bail, and a latching arrangement. Counts per Minute measurement is shown on a functional level in Figure The battery charge will automatically resume when the battery has cooled enough.

The Time Base Accuracy Test can be used as an initial accuracy determination. Set the input level to mV rms; verify a stable and correct readout.

Self Check Test 750a interval, known as the gate time, may be 0. There are three status annunciators. Refer to Section 5 for ordering information.

The measurement cycle rate time between successive measurements is determined by an exterior RC network connected to pin CR. This entry indicates the recommended number of spare parts necessary to support one to five instruments for a period of two years. For either Channel, the input signal is amplified, filtered, and shaped to provide an output at ECL logic levels.

Model Y mounts a single “C” case in a panel arrangement. As illustrated in Figurea large dc component can shift an input signal away from the hysteresis levels necessary for proper triggering.
