1.5 Control Keys/Functions
1.5.1 Turning the Device ON/OFF
ON/OFF key: push for 2 s to activate.
1.5.2 Starting and Stopping a Measurement
(START/STOP)
The START/STOP key initiates and stops a meas-
urement, even if no radiation is present.
The device has an Autostart feature. With Autostart,
a measurement begins as soon as radiation is de-
tected.
The timer measurement is disabled.
1.5.3 RESET Key
RESET sets all parameter readings back to zero.
RESET can also be used to clear an overload mes-
sage “OL”. After activation of the RESET key,
DIADOS E is in the Autostart mode.
An automatic zero adjustment process can be
aborted with the RESET key.
A measurement initiated with Autostart can also be
aborted with RESET. All parameter readings will be
reset to zero.
1.5.4 Zero Adjustment (
ZERO
)
The keys
ALT
+ RESET will cause DIADOS E to
perform a zero adjustment. For the zero adjust-
ment, the detector and the extension cable used for
the measurement must be connected. During this
process, avoid moving or irradiating the detector
and the cable. Perform the zero adjustment after
setup and immediately before performing a meas-
urement. During zero adjustment the message “Ze-
roing” appears on the display, and the remaining
time in seconds is displayed.
The zero adjustment process can be aborted with
the RESET key. In this case the previous device
settings will be retained.
The zero adjustment should be repeated for follow-
ing cases:
after changing the detector or
after performing a reset the displayed value for
dose rate climbs up without radiation.
