Appendix 2

Generic TelePole Calibration

1. It is possible to set/change all the factors outside the radiation chamber.

2. When the radiation field is lower than 10 mR/h, it is possible to change all the factors.

3. When in the calibration mode and the external radiation field is lower than 10 mR/h,

pressing the MODE push-button can switch between the different factors.

4. Suggested procedure:

4.1 Turn the internal switch to the calibration position.

4.2 Press the MODE push-button twice to enter the calibration mode.

4.3 Expose the TelePole to a radiation field of 50 mR/h ±20mR/h. The meter will be

automatically set to factor F1. Now the factor can be changed either by pressing the

RESET or LIGHT push-button or taking the meter outside the radiation chamber and

adjust the factor F1.

Place the TelePole back inside the radiation chamber and expose it to a radiation field

of 50 mR/h. Check that the meter's reading and the radiation field are equal.

4.4 Expose the TelePole to a radiation field of 350 mR/h ±50mR/h. The meter will be

automatically set to factor F2. Now the factor can be changed either by pressing the

RESET or LIGHT push-button or taking the meter outside the radiation chamber, the

radiation field should be lower than 10 mR/h. Notice if the current displayed radiation

factor is F2. If the factor is not F2 press the MODE push-button to switch to F2.

Adjust F2 by pressing the RESET or LIGHT push-button.

Place the TelePole back inside the radiation chamber and expose it to a radiation field

of 350 mR/h. Check that the meter's reading and the radiation field are equal.

4.5 Expose the TelePole to a radiation field of 10 R/h ±2 R/h. The meter will be

automatically set to factor F3. Now the factor can be changed either by pressing the

RESET or LIGHT push-button or taking the meter outside the radiation chamber, the

radiation field should be lower than 10 mR/h. Notice if the current displayed radiation

factor is F3. If the factor is not F3 press the MODE push-button to switch to F3.

Adjust F3 by pressing the RESET or LIGHT push-button.

Place the TelePole back inside the radiation chamber and expose it to a radiation field

of 10 R/h. Check that the meter's reading and the radiation field are equal.

4.6 Expose the TelePole to a radiation field of 350 R/h ±50 R/h. The meter will be

automatically set to factor F4. Now the factor can be changed either by pressing the

RESET or LIGHT push-button or taking the meter outside the radiation chamber, the

radiation field shold be lower than 10 mR/h. Notice if the current displayed radiation

factor is F4. If the factor is not F4 press the MODE push-button to switch to F4.

Adjust F4 by pressing the RESET or LIGHT push-button.

Place the TelePole back inside the radiation chamber and expose it to a radiation field

of 350 R/h. Check that the meter's reading and the radiation field are equal.
