EXTERNAL CALIBRATION SUMMARY
1. Connect the peripheral equipment to be included in the calibration. (See Figure 6.1
for an example of how to connect an Isoamp to the calibration circuit for referenced
CR measurements.)
2. Set the frequency to the lowest frequency to be used in your survey. (e.g. 0.125 Hz)
3. Set cycles to 16.
4. Set the notch filter to be used for this Survey Program.
5. Press the
function key.
6. Press
to “Create new calibrate records”.
7. Press
Enter
to proceed.
8. Press for “External” voltage source.
9. Press
Enter
to select the default calibrate voltage (Cal=1.000V).
10. Press
Enter
. The program now sets all gains to 1, and pauses to enable the operator
to change gains and attenuator settings.
11. Press
Enter
to automatically gather calibration data from the starting frequency to
the highest frequency available in the selected program.
12. To limit the calibration to a particular frequency range, press
Escape
at the
appropriate frequency. If you halt the calibration routine, you must answer the
question: “Exit auto-cal mode? (1 - yes, 2 - no)”. Press
to change the frequency, number of cycles, or calibration voltage, and then proceed
with the calibration. The calibration data is stored in the corresponding calibration
cache, and in the main field data cache.
13. To terminate the calibration before it completes its cycle for all frequencies, press
Escape
and then to exit the autocal mode [“Exit autocal mode? (1
- yes, 2 - no)”].
14. When the calibration is complete, a system check is recommended.
