alpha/beta measurement one can select the view in three vari-
ants: Alpha and beta values as large display, alpha values large
and beta values on the info bar, beta values large and alpha
values on the info bar.
Store measured values Up to 2,400 individual measured values can be stored and
transferred to a PC or a memory stick via USB interface. The
important parameters are saved with the stored values. This
depends on the measurement mode.
The memory can be used as a memory with fixed length or as a
FIFO. With FIFO there is a write and a read pointer. If FIFO is
full, everything starts again from scratch and the oldest value is
overwritten. The FIFO can be read out and edited via the USB
interface using special commands. In a fixed-length memory
storing ends when it is full and an error message is displayed; a
status bit is set.
The following data is stored for each measurement: Date/time,
status, measuring time, measured value 1 (alpha), measured
value 2 (beta), unit, integral value 1, integral value 2, unit inte-
gral value, integral time (h).
The status includes: Probe type, detector failure, alarm 1, alarm
2, integral alarm 1, integral alarm 2, measurement active, FIFO
75% full, memory full, measuring range OVR1, measuring
range OVR2, beta channel invalid. A total of 12 ASCII HEX
characters.
