Note: BEEP mode only
works with CUMULATIVE
data and for Sample Times
greater or equal to 6
seconds.
• BEEP - In this mode, the instrument is pre-configured to beep
according to the alarm threshold set in Alarm Configuration and the
instrument’s sample time if the instrument is set to collect
cumulative data. Counting starts one second after the START
button is pressed and will continue until the STOP button is
pressed.
If no channel is set for alarming and BEEP mode is selected, the
smallest channel size will be automatically selected and its alarm
threshold will be used to trigger the alarm.
Note:
BEEP mode only
works with CUMULATIVE
data.
If alarming is enabled on more than one channel size, only the
smallest channel size will be used to trigger the alarm in BEEP
mode. Larger channel sizes will be ignored.
Note:
If BEEP mode is
set to one count, the beeps
may not be for every single
count.
The data will be recorded based on the set sample time and hold
time and can be viewed in the View Buffer and on the printouts.
There will be no indication on the record, however, that the data
was saved while the instrument was in BEEP mode.
Geiger Counter Mode
While in BEEP mode the instrument can be set to beep 1 to 4 beeps per
second depending on the number of particles the instrument has
counted per second.
To set up the instrument for Geiger Counter Mode:
1. Enable BEEP Mode.
2. Set the smallest particle channel to 1.
In Geiger Counter Mode the instrument will beep from 1 beep up to 4
beeps per second if it counts from 1 particle up to 4 particles per
second. The maximum beeps per second the instrument can emit are 4
per second even if the instrument counts 100 particles per second.
The value set in the smallest particle channel’s alarm is the trigger for a
single beep per second. If the smallest particle channel is set to 2, the
instrument will beep once every second for every 2 particles the
instrument counts per second.
