Operators Manual
3-4
We recommend that the probe be secured to the
mating probe adapter receptacle using heat shrink
tubing
.
4. Secure the Philips screw located on the top panel of the adapter.
3.6 Power
The Model 190 is powered using four 9-volt alkaline batteries. The batteries (four) are housed in a
separate compartment accessed from the instrument back panel. All four 9-volt alkaline batteries are
required to operate the unit for approximately 200 hours. Visual and audible low battery indications are
provided whenever battery power is low (four minute intervals for the audible and continuous for the visual
after a battery test).
3.7 Readout
Measurement results are indicated on the front panel LCD. The display includes an analog bargraph,
scale multiplier, detector range bargraph, and a 16 character alphanumeric display (refer to Figure 3-3).
Each of the 51 elements in the bargraph represents 2% of the scale span. The analog bar graph is
divided into 5 sections with scale notations of 0, 2, 4, 6, 8, and 10. The scale sections are marked by
longer bars. The bars are arranged in an arc with a radius of 3.75 inches (9.5 cm.). Scale length is 2
inches (5 cm.).
The 51 element analog bargraph, located near the top of the display, provides real time response. It is
designed to emulate an analog meter movement, making it especially useful in survey applications. The
16 character alphanumeric display at the bottom of the LCD displays units, an average digitized value of
the reading, error messages, integrated value (with elapsed time), operational parameters (e.g., response
time), low battery indication, probe type and serial number, and data logging information.
A scale multiplier, located below the bargraph relates the analog bargraph full scale to the units displayed.
The detector range bargraph consists of five horizontal bars that indicate the decade of the dynamic
range in cpm of the detector in use. Most detectors will cover a dynamic counting range of five decades.
A few detectors (e.g., those with short dead times) can reach the sixth decade of operation. The sixth
decade is indicated by all five bars being lit.
The bargraph may be disabled using the Model
190-1A Communicator.
In the Alarm condition, the entire display blinks on and off with a period of two seconds
