le to use
when operating solely from the 9-Volt battery inside the PRM Instrument. The current
Power Setting will be displayed. Press
to change.
The power settings are outlined in the table below. The factory default for battery opera-
tion is Lowest. In this setting the LCD will be turned off after 60 seconds of inactivity.
While continuing to measure nuclear radiation, the unit will enter a sleep mode in order
to conserve battery power. Once any key is pressed the LCD will resume normal opera-
tion. In the Lowest setting the backlight will be turned off after 15 seconds.
8.8 External Power Management Setting (Ex-Pwr:)
This setting allows the user to specify what battery power management pro
fi
le to use
when operating from an external power source connected to the power connector of the
PRM Instrument. The current Power Setting will be displayed. Press
to change.
The power settings are outlined in the table below. The factory default for external power
operation is High. In this setting the LCD and backlight will remain on. The unit detects
when external power at the proper voltage is present and will activate the external power
management setting. Similarly, the unit senses the removal of the external source and
will resume the battery power setting.
External power management is very useful for remote, long-term application of the PRM
Instrument where the device is powered by large external batteries or alternative sources
such as solar cells.
