| Modes: |
| Integrate mode: |
Operates continuously 30 seconds after the
instrument has been turned on. Integration is performed even if the
instrument is displaying in mR/h or R/h |
| Freeze mode: |
Will place a tick mark on the bar graph display
to hold on the peak displayed value. The unit will continue to read and
display current radiation values |

LCD analog/digital with backlight |
| Analog: |
100 element bar graph 6.4 cm long. Bar graph is
divided into 5 major segments, each labeled with the appropriate value
for the range of the instrument |
| Digital: |
2.5 digit display is followed by a significant
zero digit depending on the operating range of the instrument. The units
of measurement are indicated on the display at all times. Digits are
0.25 in (6.4 mm) high. Low battery and freeze indicators are also
provided on the display |
