| | The “Cypher” is an advanced survey instrument. It is very user friendly and uses digital technology to greatly enhance its operation. It works with most GM, proportional, and scintillator probes and displays the information on a backlit alphanumeric LCD. The display has a moving pointer bargraph that closely approximates a meter movement. It is smooth, easy to read and accurate. The digital level and the bargraph scale are also shown on the display.
The instrument has many different modes including rate, integrate, and scaler. Each mode is independently programmable and may be turned off. It can be set up as a simple ratemeter with only one mode or it can be set up for all 6 modes. Thus it can be easily adjusted to suit your application. If that application changes it is easy to reconfigure for a new one. This instrument helps you get the readings you want. It is difficult to misread the data with the units and range information shown right on the display.
The 4 soft-key buttons on the front panel operate the instrument. The two on the right are user defined. One user may want to use them for light and beeper while another may want to use them for range hold and reset. The soft-keys also help to simplify the operation of the instrument. There is only one level of display; you are never lost in a maze of menus.
The digital nature of the instrument means that setup, calibration and maintenance are greatly simplified. Many of the operational and calibration functions can be controlled or set from either the front panel or the inside panel or both. The accuracy of the data is assured by a crystal controlled timebase and the switchable deadtime correction extends the linear range of most probes.
The “Cypher” survey instrument is small, rugged, and light. It is simple to operate, loaded with features and programmable for either simple or advanced uses. It is the perfect all around instrument.
