SURVEY SENSOR: ZERO ADJUST
A zero adjustment is needed either when prompted by the instrument or when the dose rate appears too high even
if no radiation is present. You can initiate a zero adjustment by pressing the >0< button. You will then get the
option to either adjust, or to reset to the factory zero.
ADJUST
A new zero adjustment will vary between 30 and 90 seconds, depending on environmental factors, such as
temperature. If the zero adjustment fails, try again. Make sure that the temperature is stable and that the sensor is
not irradiated during the process.
RESET
The factory zero is a generic zero adjustment performed when the sensor was produced. It is designed to be valid
for most measurement occasions. You can reset to the factory zero at any time by pressing >0< and then Reset.
This can be useful for example in an environment without possibility to shield the sensor from radiation, which is
needed to get a proper result from a zero adjustment.
NOTE! The zero adjustment is saved in the base unit.
