We shall now discuss in detail the particular states, including the action of the on/off key and the signal
Dose rate indication looks as follows:
The right-hand example shows how the type of the external probe is indicated as »ext xy« in the upper
left corner, and that for pulse probes the unit s
will be selected. The probe code »xy« below the »ext«
symbol may take one of the following values:
for the Gamma Probe 6150AD-15,
for the Gamma Probe 6150AD-18,
for the Alpha-Beta-Gamma Probe 6150AD-17,
for the Liquid-Sample Probe 6150AD-19,
for the Teletector Probe 6150AD-t (low range tube),
for the Teletector Probe 6150AD-t (high range tube),,
for any pulse probe with straight pulse rate indication, e.g. 6150AD-k,
for the Scintillator Probe 6150AD-b (only with a 6150AD5/6 as a meter).
The digital dose rate indication always comprises three digits. Section 6.1 describes the format in detail.
The loudspeaker symbol in the upper right corner indicates whether audible single pulse detection is
enabled. In case of dose rate alarm, the symbol flashes (with /E models, the analog scale divisions
The signal key clears the dose rate warning tone (the flashing loudspeaker symbol will remain). If the
dose rate warning tone is off, the signal key switches audible single pulse detection alternately on and
In the dose rate indication state (and only in this state) you may switch off the 6150AD3/4/5/6 by
pressing the on/off key twice within three seconds.
external probe, e.g. 6150AD-17:
