SMOOTH MOVING POINTER BARGRAPH
W/ RANGE HOLD
AND INTEGRATE MODES
KEYS, UNITS, & RANGES
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
