The uncalibrated version requires the operator to load the matching probe data file into the cable PROM directly from the Model front panel. The small nonlinearities present in each individual device can be measured and subtracted from the field reading. Normal Reading — the display configured to show the RMS field value and frequency, and the probe temperature. A signal is said to be properly sampled if the original signal can be exactly reconstructed from the digital information. We also offer other probes.

Does not include probe error, unless otherwise specified Input type: In many cases, gaussmetef provides the functionality of two or more instruments in a field measurement system.
In this case, analog output 1 should be used to monitor the signal. The relays can also be controlled manually for other system needs. Keeping probes and their extensions from getting mixed up can become a problem when more than one probe is in use. Those signals are then sent to the digital signal processing DSP circuitry where the signal processing is done and the readings are filtered.
Signal quality degrades at high frequency because of the sampling rate. Lake Shore Cryotronics, Inc. This voltage is corrected for lahview nominal sensitivity of the probe and provides the widest bandwidth of the three voltage outputs. One of the built-in analog voltage outputs drives the program input of the power supply for either bipolar or unipolar operation. This is ideal for most magnetizers and other fast pulse applications.

Max Peak Hold On — the display configured to both show the positive and negative Peak readings. The Model offers a variety of features to enhance the usability and convenience of the gaussmeter. LED annunciator, beeper, and relays Relays Number: Signal quality degrades at high frequency because of the sampling rate.
Indicated by digit number in above table Max reading rate: The uncalibrated version requires the operator to load the matching probe data file into the cable PROM directly from the Model front panel.
This differs from the faster peak capture feature that operates on broadband, unprocessed field reading information. We also offer other probes beginning on page In wideband AC mode, the signal can be viewed on an oscilloscope to observe the shape of AC fields.
Trigger in and trigger out A TTL-level hardware trigger into the instrument can be used to initiate the data log sequence.
This is ideal for most magnetizers and other fast pulse applications. Other Hall probes are available. Lake Shore Cryotronics, Inc.
Gauussmeter wide band AC mode, the signal can be viewed on an oscilloscope to observe the shape of AC fields. The relays can also be controlled manually for other system needs. The Model has a two line by 20 character vacuum fluorescent display.
Recalibration requires a computer interface and precision low resistance standards of known value. Follows alarm or operated manually Connector: Probe temperature effects can be measured and subtracted out of field readings.
Normal reading—the display configured to show the RMS field value and frequency, and the probe temperature Max DC hold on—the display configured to show both the Maximum and Minimum DC field values Max peak hold on—the display configured to both show the positive and negative Peak readings Field control on—the display configured to show the field control setpoint and current field gaussmdter, when field control is active Keypad The instrument has a position keypad with individual keys assigned to frequently used features.

The keypad can be locked out to prevent unintended changes of instrument setup. Although temperature effects contribute only a small fraction of the overall probe measurement accuracy, temperature compensation will often improve measurement and control stability.
This reduces interface overhead, enabling real-time reading rates up to new readings per second. Relative feature calculates 457 difference between a live reading and the relative setpoint to highlight deviation from a known field point. Hall effect devices show a slight change in sensitivity and offset with temperature. Data buffer Internal memory provides storage for field readings in a data buffer.
