CALIBRATION

Due to the natural performance drift of electronic components,
regular calibration is essential for high-precision measurement in
a long run use to remove deviations for reliable results. The recom-
mended calibration interval for the
The ADMX3652 adopts three point correction: zero, positive full
scale, and negative full scale. In principle, zero calibration removes
offset, and positive full scale and negative full scale calibration
remove gain errors.
Note that, if the board is soldered onto the board of the user, it is
assumed that the suggested circuitry in the
section was added on the board for simple access.

functionality. Use a high-precision calibrator, such as the Fluke
5720A, and the EVAL-ADMX3652-INT interface board as a carry
board to build a calibration system by taking the following steps:
1. Mount the ADMX3652 to EVAL-ADMX3652-INT interface board.
Connect the EVAL-ADMX3652-INT interface board to the host
computer and calibrator.
2. Power on and warm up the ADMX3652 for at least 30 minutes,
and then connect the Channel 1 (CH1) port to the calibrator via
a coaxial cable. Set the NPLC of both channels to 100 in the
ADMX3652 Evaluation GUI Software, and Channel 1 is ready
to calibrate.
3. In ADMX3652 Evaluation GUI Software interface, click Cali-
brate and the ADMX3652 Evaluation GUI Software switches
to the calibration interface.

5. Set the calibrator to output 0 V, type 0 in the input box, and click
Calibrate: 0 V to complete the zero calibration for the 0.2 V
range. The background of Calibrate: 0 V is reversed after being
clicked.

6. Set the calibrator to output 0.2 V (the positive full scale of the
calibration range), then type 0.2 in the input box, and click
Calibrate: 0.2V to complete the positive full-scale calibration for
the 0.2 V range.
7. Set the calibrator to output −0.2 V (the negative full scale of
the calibration range), then type −0.2 in the input box, and click
Calibrate: -0.2V to complete the negative full-scale calibration
for the 0.2 V range.
8. Repeat Step 4 to Step 7 to complete calibration for the 2 V
range and 20 V range.
9. Change hardware to feed the calibrator to Channel 2, and
repeat Step 4 to Step 8 to complete calibration for Channel 2.
10. Select the Date and click Save Calibration Date and Data to
load and activate the new calibration data.
Note that it is not recommended to manually change the date
as the GUI reads the date automatically, unless the user inten-
tionally selects a different date.
