Chapter 1. Definitions
Automatic
The following parameters can be set to automatic or manual
mode: In the automatic mode the value is calculated using a for-
mula. Enter -1 to enable the automatic mode. The inverted C in
the top row indicates whether a parameter has been set to auto-
matic.
Cassette
Case (7 TE) into which the evaluation unit LB 4710 is installed, so
it can be used in any 19“ rack
Count rate
Value of counts relative to one second.
cps
Count rate unit: c ounts p er s econd.
Edit
Change value
Edit mode
In this mode, a value can be changed. Not every parameter can
be changed since some parameters are only used as display val-
ues. Editable Parameters can be set to the edit mode with the
"Enter" button. In the edit mode the cursor positioned over a digit
is flashing.
Empty
Level below monitoring height
Empty count rate
Count rate with empty container
EVU
Ev aluation U nit
Operating unit with electronics. Parameters are set and the meas-
urement is calibrated on the EVU. Typically, the EVU is accommo-
dated in the switch room or in a wall housing on site.
Factory setting
All parameters have been preset by the manufacturer using
standard values. In most cases this simplifies calibration of the
instrument significantly. Despite factory setting, calibration always
has to be performed.
Fixed value
Some parameters can be set automatically or manually (see page
14). To set a parameter to manual, you have to enter a fixed val-
ue or a value >0.
FSK detector
Detector with digital communication
(FSK =
F requency S hift K eying)
FSK detectors are intelligent detectors with self-diagnosis. Infor-
mation to and from the evaluation unit is transferred via serial
data protocols.
All NaI and Super-Sens detectors are FSK detectors
Type designation: LB 54XX and LB 44XX. See also hardware man-
ual.
