POSITION A
:
NOT USED
POSITION B
: LCD Backlight
ON TIME
is the amount of time that the LCD
backlight will stay on after pressing the front-panel switch labeled
LIGHT
.
This value is stored in EEPROM.
Available values are:
5 seconds
30 seconds
60, 90 seconds
180, 240 seconds.
POSITION C
:
SET MINIMUM DISPLAY
sets the ratemeter minimum
displayable reading. Depressing the
RESET
button displays the minimum
ratemeter units. The readout will auto-range up to the maximum
displayable but will display zero for ratemeter readings below the user-
programmed minimum variable.
Minimum displayable values are:
00.0 µ, 000 µ, 0.00 m, 00.0 m, 000 m, 0.00, 00.0, 000
R/hr
.000 µ, 000 µ, 00.0 m, 000 m, 0.00, 00.0, 000 Sv/h
0.00, 00.0, 000, 0.00 k, 00.0 k, 000 kcpm, or cps
POSITION D
: RS-232
DATA DUMP MODE
allows the RS-232 port to
dump ratemeter data every two seconds. The Model 2241-2 is fully
functional during RS-232 data dump with the exception of the audio
function. The LCD will alternate between display of the ratemeter and
the word “
dUP
” (representing "dump").
POSITION E
: RS-232
DETECTOR PARAMETERS SETUP MODE
allows the
RS-232 port to accept/send a string of parameters corresponding to the
current detector setup values.
POSITION F
: BAUD RATE configures the RS-232 port for the
following baud: 150, 300, 600, 1200, 2400, 4800, 9600, and 19200. The
data is eight data bits, one stop bit with no parity bit. This value is stored
in EEPROM. The baud rate can only be programmed through the
switch board.
