the “cypher” is an advanced survey instrument. it is very user friendly【敏感词】uses digital technology to greatly enhance its operation. it works with most gm, proportional,【敏感词】scintillator probes【敏感词】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【敏感词】accurate. the digital level【敏感词】the bargraph scale are also shown on the display.
the instrument has many different modes including rate, integrate,【敏感词】scaler. each mode is independently programmable【敏感词】may be turned off. it can be【敏感词】up as a simple ratemeter with only one mode【敏感词】it can be【敏感词】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【敏感词】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【敏感词】beeper while another may want to use them for range hold【敏感词】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【敏感词】maintenance are greatly simplified. many of the operational【敏感词】calibration functions can be controlled【敏感词】set from either the front panel【敏感词】the inside panel【敏感词】both. the accuracy of the data is assured by a crystal controlled timebase【敏感词】the switchable deadtime correction extends the linear range of most probes.
the “cypher” survey instrument is small, rugged,【敏感词】light. it is simple to operate, loaded with features【敏感词】programmable for either simple【敏感词】advanced uses. it is the perfect all around instrument.
