Linearity compensation, temperature compensation, auto probe zero, and hot swap Measurement features: The gaussmeter reads the probe information on power up or any time the probe is changed to allow hot swapping of probes. This differs from the faster peak capture feature that operates on broadband, unprocessed field reading information. Recalibrations are always available from Lake Shore, but the Model allows users to field calibrate the instrument if necessary. The relays can also be controlled manually for other system needs.

Peak measurement mode Pulsed fields are measured in Peak mode, which is a natural extension of the highspeed data acquisition necessary for DSP operation.
High and low alarms are included in the instrument.
Model | Overview | Lake Shore Cryotronics, Inc.
The second voltage output provides a voltage proportional to measured field with the benefits of some signal processing. Model probes are calibrated in this way to provide the most accurate DC readings. In this case, analog output 1 should be used to monitor the signal. Analog Output 2 is corrected for nominal probe sensitivity and probe zero offset.
Users can program nominal sensitivity and serial number into an optional MCBL-6 blank connector to provide all gaussmeter functions except field and temperature compensation. The relays can also be controlled manually for other system needs. Frontend amplification specifically designed to complement DSP data acquisition provides high stability and repeatability. Autorange works in DC and AC measurement modes.
Allows the user to zero all ranges for the selected measurement mode with the push of a key.
Keeping probes and their extensions from getting mixed up can become a problem when more llabview one probe is in use. Calibrated or uncalibrated probe extension cables with an EEPROM are available from 10 ft to ft — More information on Extension cable compatibility Lake Shore calibrated extension cables maintain the same accuracy as the Model probe. The Model alleviates most of the hassle by allowing users to match probes to extensions in the field.
The Model alleviates most of the hassle by allowing users to match probes to extensions in the field. In wideband AC mode, the signal can be viewed on an oscilloscope to observe the shape of AC fields. Menus are reserved for less frequently used setup operations. One of the built-in analog voltage outputs drives the program input of the power supply for either bipolar labveiw unipolar operation.

In analog processing, the components used have different values from component to component and are temperature dependent.
Mode complex nature of Hall effect measurements make it necessary to match extension cables to the probe when longer cables are needed. The Model will operate with a discrete Hall effect generator when a suitable probe is not available.
The exclusive DSP algorithms free the Model from the limitations of conventional RMS conversion hardware and provide for an excellent dynamic range, resolution, and frequency response.
The sampling and filtering in the Model can allow realizable resolutions of 20 bits, which is in the noise floor of the instrument. The Model has several capabilities that allow the best possible measurements with Lake Shore probes. This differs from the faster peak capture feature that operates on broadband, unprocessed field reading information.
An IEEE software-based trigger can be used like the hardware trigger in. Indicated by number of digits in above table Max reading rate: Typically, the resolution is high enough and enough averaging is done that it does not present a problem.

Hardware trigger to begin data log sequence Alarm Settings: Following are three examples of the various display configurations: The small nonlinearities present in each individual device can be measured and subtracted from the field reading. The operator can also control display brightness. A TTL-level hardware trigger into the instrument can be used to initiate the data log sequence. Follows alarm or operated manually Connector:
